Ways to Set Up a Wireless Access Point

Ways to Set Up a Wireless Access Point

For broadcasting or extending the range of a wireless network or allowing a wired network to broadcast wirelessly, one piece of networking equipment is used and that is a wireless access point or WAP. Below is an in-depth explanation on setting up a wireless access point for your home network.

How to Install a Wireless Access Point

Steps on how to set up a wireless access point are:

Network information
Your WAP acts as a go-between device, between your router and computers trying to connect to your home network. Hence, the wireless settings of your router should be inputed onto your WAP, so that the wireless access point picks up and broadcasts the correct signal. Before doing anything with the access point, you will need the following information from your router:

LAN:

  • Router’s IP address
  • DHCP address range
  • Wireless:
  • Wireless network name or SSID
  • Wireless channel being used
  • Security mode being used (WEP, WPA etc.)
  • Password or security key (copy all the settings, such as number of keys, encryption type etc. to be safe)

Please write down the above data correctly. A slight change in the settings and nothing will work. To obtain such information, you will need to log onto your router’s setup page. If you are familiar with the process or know the settings, skip the following steps:

I. Use any computer that is hard wired to your router. Do not connect to your router’s page wirelessly.

II. On that computer, open the Command Prompt and in the black screen, type the command ipconfig.

III. Look for the field Default Gateway. An example of what it may look like: “192.168.1.1”. Write this down, this is your router’s IP address.

IV. Close the command prompt and open any web browser. Delete any URL in the Address bar and type in your router’s IP address. Press Enter.

V. A dialog box will appear asking for your router’s username and password (not related at all to your wireless network). If you have enabled any, please enter it now. The default login information for most routers is a blank username and password: admin. Click on Ok.

VI. At the main setup screen, look for DHCP Range and DHCP start and end addresses. Write this down.

VII. Now look for a tab at the top of the screen, that says Wireless or Wireless Settings. Click on said tab, there may be sub tabs like basic, security and advanced. Look for the wireless information details mentioned above (SSID, security etc.) and write them down.

VIII. Check if you have enabled broadcasting of your network name, i.e. your network name is seen and you connect by selecting it. This option is usually termed as SSID broadcast and is found in the wireless settings page.

Connecting the WAP

1. Now it’s time to deal with the access point. Connect an Ethernet cable to the port on the WAP and the other end of the wire to the Ethernet port on your computer, such that the WAP and a computer are hard-wired together. Turn on the access point.

2. Open the Command Prompt and type ipconfig/renew. Then type ipconfig. Look for the Default Gateway address, this is currently your WAP’s address, which needs to be changed.

3. Open a web browser and type this address in the Address bar. Log in to the page, (username blank, password:admin) and now you are on the WAP’s setup page.

4. The default mode for functioning is Access Point in most routers. If there is any such specification on the WAP’s setup page, make sure this mode is set to Access Point only.

5. First the router’s IP address needs to be assigned. Look for the term IP address and there should be four number filled boxes beside it.

6. To help understand what the access point’s address should be, here’s an example:
Suppose your router’s IP address is 192.168.1.1 and the DHCP starting address is 192.168.1.10 and ending address is 192.168.1.15

7. Since the DHCP range is 10-15, the access point’s address should NOT be any of these numbers but should be something different. An ideal address for your access point is 192.168.1.2. So, it is within the router’s subnet range but not within the DHCP range. Type this in the IP address box. Do not type in the Default Gateway boxes.

8. Look for any option termed DHCP enabled and a possible checkbox or “yes/no”. Turn off the DHCP. With this address change, the web browser might try to refresh or a message might be shown. Close all windows.

Setting Up the Wireless Network

(i). On establishing the WAP’s address, now the physical connections have to be changed. Connect one of your router’s LAN or Ethernet ports to the port on the WAP. Connect another wire between the computer and the router’s port. Power on the access point. Now both your computer and the WAP are connected but not to each other, instead to the router.

(ii). Now on the computer, open a web browser and type in the WAP’s IP address, which was just assigned (in this scenario, 192.168.1.2) and logon to the setup page. Look for a main tab that says Wireless.

(iii). Under this tab, enter SSID and wireless channel. Look for a sub-tab that says Wireless Security and click on it. Under this, select the correct security type and type in the password or key, that is used for your network. This step is inputting the wireless settings of your router onto your access point. Once done, close the browser.

(iv). The LED’s on your access point should be lit up. Check the WAP’s manual to see if they are lit up correctly. The WAP has been set up. If you are connecting it to a wired router, leave the present connections as they are. If you have a wireless router, then you can disconnect the WAP from the router and position it in a location, such that it picks up the router’s signal and broadcasts it properly. This process is slightly “trial and error” in nature, as you need to check the signal strength for placing the wireless access point in the optimum location.

The above mentioned WAP installation procedure may seem very tedious, but you just need to be patient and read the step carefully before doing anything. Bear in mind that your access point is now configured according to your router’s wireless settings, so if you change them on the router, you have to change them on your access point.

Setting Up a Wireless Repeater Tips

Setting Up a Wireless Repeater Tips

The need for seamless, uninterrupted and reliable communication is one of the top priorities of every house. The wide access to some really useful information base, for every kind of user makes it extremely important to set up a device which delivers high-performance. There are a range of products available in the market that perform the same function. The customer is in a tizzy over the right product to be purchased. And once the purchasing is done, the next big question is to set it up.

What are Wireless Repeaters?

They are networking devices that increase the reach of the existing wireless network. Very often, it happens that a device has to be connected to an existing wireless network, but it is away in a remote place in the house or a building, where the signal strength is too low or unreachable. A wireless repeater is used in such cases to boost the signal strength or simply repeat the signal so that the said computer comes under the coverage area.

How to Set Up the Repeater?

Once the repeater is chosen as per one’s needs, the next step is to set it up. A brief idea of the steps to be followed are provided below:

  • The foremost thing is get a standard ‘cat5e’ cable, that has to be connected from the PC to the repeater.
  • Once this has been done, verify the connection made from the routers to the PC and the repeaters, to avoid problems in reception of signals.
  • Then follow the instructions on the configuration interface.
  • Next is to set the Service Set Identifier (SSID’s) that is generally same as the network settings. This relates to the subscriber identity, the network name and also the password for accessing the network.
  • Check the compatibility of the device with the computer.
  • After checking for the compatibility requirements, the MAC (Media Access Control) address used or configured for the repeater should be exactly same as that of the router setup available. This is the most frequently encountered problem while setting up a wireless repeater.
  • Perform a reset operation, a power cycle procedure and then switch on the connections.

Troubleshooting

In case, the system is not able to give satisfactory signal strength, following the mentioned troubleshooting details will help to improve it.

  • Antenna Direction: The antenna of the router is generally omnidirectional and in case it is close to a wall or a partition, much of the signal is wasted. This happens because, the signal is transferred in all directions and part of it going towards the wall is wasted. Hence, place the antenna or the router in a preferably central place or use an antenna which propagates the signal in the required direction.
  • Try Other Channels: It is always a good practice to have the USB network adapter in the machine one is using. Try to use different channels to get hooked on to the network.
  • Interference: Other devices in the vicinity of the repeater, such as mobile phones may affect the signal quality. Therefore, try to reduce the interference of wireless access by different devices.
  • Upgradation: The firmware and the device should be of decent quality and frequently checked or upgraded, for maintaining good signal strength.
  • Brand Quality: If all the network equipment is from a single seller or vendor, it is relatively easy to get service quickly and issues related to working can be addressed as soon as possible. Therefore, choosing one brand and sticking to it will give better signal strength.

Computer and communications setup can be very tricky to deal with. Despite all the efforts, if the signal strength cannot be restored or improved, seek assistance from the service provider or the device company. Adhering to the guidelines is the best way to amplify the signal strength and enjoy boundless coverage on wireless networking devices.

Ways to Detect and Stop an Outside User from Stealing Your Wi-Fi

Ways to Detect and Stop an Outside User from Stealing Your Wi-Fi

An outsider who knows how to get into your Wi-Fi can not only use it for himself, but he can also hack the data on your computer. This is very dangerous as your computer’s security is compromised. The hacker can be doing something illegal and the police would catch your IP instead. Detecting the user can be easy, but it is quite difficult to ascertain the identity, especially if all you have are the history records of his/her usage, and no addresses. Once you know if your Wi-Fi is being leached, there are some steps that you can take to prevent it from happening again. The thing is, they connect to your Wi-Fi the same way as you do, so it pays to have some figurative walls around your Wi-Fi signals.
Basics of a Wi-Fi Connection
If you don’t know much about the components (both hardware and software) in your Wi-Fi system, it would be good to know the basics of what they are, to work on them.

  • The signal for your broadband Internet connection is brought to your house through a cable or satellite modem, or a digital subscriber line (DSL).
  • The wireless router is attached to the modem, which transmits the signal through your house to give you the Wi-Fi connection in your house.
  • Your router will have a dynamic host client protocol (DCHP). Your DCHP tells your router who is allowed to access the Wi-Fi connection and who isn’t.
  • Every machine is given an Internet Protocol address or IP address. The IP address tells the router who has accessed the Wi-Fi. The IP addresses are assigned to each computer with the help of a media access control address, or a MAC address.

Detecting an Internet Thief and Stopping the Thief
Detecting an Intruder
You know someone is stealing your Wi-Fi if:

  • Your network service is slower than usual.
  • Your network service keeps breaking down intermittently.
  • Your network speed is lowered at the same times everyday.
  • Your router is ‘on’ and ‘blinking’ even if your PC is off.

You can make sure whether your Internet service is accessed by an unknown user by doing the following things:

  • You can check your router logs. This changes from router to router; you can access the ‘Help’ section to figure out where the log is stored.
  • You can see any attached devices on the router admin page. You can access the page by typing your IP address in the browser (default gateway IP retrieval explained later).
  • Check out the MAC addresses of all the attached devices (MAC addresses are unique to all devices). If any of the addresses don’t match the ones you already know, then it’s an external unknown device.

Stopping the Intruder
Once you know that there’s an unwelcome user, you can strengthen your defenses against them.

  • Since the router gives all connected devices an IP address, your main computer’s IP address should be a default address like 192.168.0.1 or 192.168.1.1 . This is the default gateway IP address of your computer. To find it out, press Start → Type “Run” → Type “cmd” in the Run tab → Type “ipconfig” in the new window that opens. You’ll get a list of things. Find the default gateway IP in there and note it down.
  • Once you get that address, type it in the browser, where you’ll get to set the router address and password. If it’s default, you don’t need to put in the password every time you access it. Which means that if the setting is default, anyone can access your router to get free Internet (you pay the bill, after all). Again, the default address and passwords are different for different brands of routers. You can get the default values from the respective brand’s site. If you are using the defaults, change the address and passwords to something secure, something totally unique, long and which only you and your family can figure out. So every time someone logs in, they have to put in the password to access the Internet.
  • If you still feel you need more security, click on the “Wireless” tab in the router folder, go to “Security” and enable the WEP encryption. You’ll have to give a WEP key for encryption. Be sure to note down this key before pressing “Accept”. All your data is now encrypted using this key. The thing is, the person stealing your Internet probably knows a thing or two about hacking and will eventually find out the key too. You can also use WPA or WPA2 encryption, it’s a little harder to hack into. It works the same as WEP and you’ll need the key to decrypt the data.
  • You can get additional security through your firewall. Turn it ‘on’ if it isn’t on already. Enable the MAC filter in the firewall setting. Add in all the MAC addresses of the computers that you want to be allowed to use the Internet, the firewall will ban the rest.

Note that all the steps mentioned are more for slowing down rather than stopping, depending on the skill of the unknown user. Also, since the range of your Wi-Fi is so small, you may also be able to see who is using the Internet. If you’re not really confident about messing with your computer settings, you can use a software like ‘Who Is On My Wi-Fi’ to find out who is using it. Once you figure out, you can successfully report the thief to the authorities.

Guide to Make a Wi-Fi Antenna

Guide to Make a Wi-Fi Antenna

Commercial Wi-Fi receptors cost you a bomb. There are alternate ways to make a Wi-Fi antenna at home that will not only increase the range of your network, but will also be very inexpensive. An antenna is nothing but a directional waveguide device that converts electrical power to radio signals, and vice-versa. Hence, pretty much any material that is capable, or can be made capable, of this function can be used as a Wi-Fi antenna.

A ‘cantenna’ is a directional wavelength reception device for long-range Wi-Fi. Ideally, a cantenna’s periphery is not strong enough to receive signals all by itself. Hence, cantennas are mostly used to extend a wireless network’s range or to improve reception over a distorted signal path. A cantenna can also amplify signals from 5 – 22 dB. While a ‘Pringles’ can is widely used for such setups, it is important to note that these cans are narrow in diameter and inappropriate for 2.4Ghz. Hence, for such a project, always use a can about 3.5 to 4 inches in diameter and approximately 6 or more inches in length.

Building a Homemade Wi-Fi Antenna using a Can

Materials and Tools
~ Can (about 3.5 inches in diameter)
~ Solder paste
~ 1.5 to 2 inches length thin copper wire strand
~ N-female chassis mount connector
~ Pigtail cable
~ Duct tape
~ Tripod stand
~ Drill machine
~ Soldering iron

Drill a hole in the can about a couple of inches from its base. Widen the hole according to the connector’s diameter.

The connector should just fit in; the hole should not be too small to get the connector in, nor too big so the connector falls off.

Set the adapter in the hole firmly.

Make sure it is set like how it is displayed in this image.

To the connector’s inside end (inside the can), solder a copper wire strand.

Be very careful when you solder the copper wire strand. This is how it must look like.

Plug in a pigtail cable into the connector outside the can.

Connect the other end of the pigtail cable to the Wi-Fi device/card. This will work only if you have a compatible Wi-Fi adapter. Hence, before proceeding, check the connector and adapter compatibility.

Mount the can on the tripod using duct tape, facing the Wi-Fi adapter. Once mounted and steadfastly in place, rotate the cantenna on its axis slightly, and adjust its tilt to work out the position in which it receives the strongest signal. This antenna has linear polarization, i.e., its rotation affects signal strength, positively or negatively. The tilt, though, is required in only very rare cases, and should be done carefully and only if necessary.

Once you shift the cantenna’s position to gain optimum signal strength, you can use your homemade Wi-Fi antenna!
Building a Homemade Wi-Fi Antenna using a Strainer

Materials
~ Strainer
~ USB Wi-Fi adapter
~ USB extension cable (at least 15 feet in length)
~ Duct tape
~ Wooden stick
~ Tripod stand

Using the USB extension cable, connect the Wi-Fi adapter to your computer. The cable’s female connector goes in your computer and the Wi-Fi adapter is inserted in the cable’s male port. If you haven’t found an extension cable long enough to position the antenna where you need, connect multiple cables together.

Using duct tape, attach the USB adapter to the handle of the strainer. If the strainer does not have a handle, attach a wooden stick to it using duct tape, and tape your adapter to the wooden stick.

Make sure your dongle is at a point where you receive signals at maximum strength. Temporarily place the dongle on the handle of the strainer and shift its place around the handle to find the hot spot.

Aim the strainer towards the Wi-Fi transmitter in a straight line and straddle a little to the left or right depending on where you are getting the best signals. Once you have figured out the exact spot which generates best strength of the Wi-Fi signal, mount the strainer on a tripod stand and get ready to use your strainer Wi-Fi antenna!
As compared to expensive Wi-Fi antennas, homemade antennas can be made and setup in almost half the price. A cantenna in fact, will not take your total expenses above $15 – $20! A strainer antenna too wouldn’t cost you more than $25. So get the materials, ready your tools and save some money!

Wireless Internet Access Through Mobile Internet Service

Wireless Internet Access Through Mobile Internet Service

Mobile Internet is about connecting to the Internet with mobile devices like cell phones, PDAs, game consoles, laptops, and other portables. Which means that you get to stay connected wherever you are and even on the move; you don’t have to be near a Wi-Fi spot to be able to access the Internet.

This has come about as a boon for everyone, from backpackers and businessmen to commuters and curmudgeons. If you want to blog about your travels, you don’t have to clamber down the steep hill you’ve just hiked up, you can simply write your blog using your mobile phone. If you want to conduct a business transaction or check the stock market, you can do it on your cell phone, your PDA, or your laptop. You can also make plane, train, car, or hotel reservations, or search for directions on interactive maps if you happen to lose your way. You can email or chat with your family and friends on the go. You can stop grumbling about being ‘stuck’ in the office, classroom, or your home, and go do your work in your favorite coffeehouse or park. So in a sense, mobile Internet can lighten up your life, if you will let it, that is, and don’t ponder too much about the dark aspects of staying perpetually connected.

Accessing the Internet over a cell phone or a PDA is not going to be the same experience as surfing the net on your regular computer. Some of the drawbacks of mobile Internet are:

  • The screen display sizes of cell phones and PDAs are very small and it can be problematic viewing text and graphics meant for standard computer screens. In this regard, PDAs are a better bet than cell phones, and laptops, of course, don’t face this issue.
  • You can’t view regular webpages in the format they are meant to be viewed.
  • You can view only one window at a time on cell phones and PDAs, and scroll just up and down.
  • You may find it troublesome or impossible to view PDFs, Flash sites, and video sites.
  • Typing out large entries using small keypads is an inconvenient process. Getting keyboards that fold open may be helpful here. But then again there may be a character limit on the messages you can send.
  • The mobile Internet connection may be very slow.

Mobile Internet Service

WAP
WAP is short for Wireless Access Protocol. WAP enables Internet access through your mobile devices, and makes it possible to use interactive data applications on them. So, it’s a breeze to check cricket scores, browse the news, download music, and see what’s happening on the stock market.

i-Mod
i-Mod is a wireless data protocol system from Japan that is slowly and steadily becoming a good competition for WAP.

GSM
GSM is an acronym for Global System for Mobile communication. GSM technology compresses information and transfers it through a single channel. Users can use GPRS (General Packet Radio Service) for WAP access, SMS, MMS, email, and surfing.

CDMA
CDMA stands for Code Division Multiple Access. With CDMA technology, information is transferred through different channels, not just one like with GSM.

EDGE
EDGE stands for Enhanced Data rates for GSM Evolution. It is also known as Enhanced GPRS or EGPRS. EDGE has better data transmission rates than GPRS and the data transmission reliability is higher too. This is a better choice for multimedia applications.

The usability and interoperability issues with mobile Internet are likely to get ironed out over the next few years, and perhaps all devices, whether fixed or mobile, will operate on wireless IP technologies. This might play a big role in narrowing the digital divide. Cell phones, after all, are much less expensive than PCs―or, for that matter, than PDAs and laptops―and nowadays have become a must-have accessory with a growing percentage of the world’s population. Getting connected to the Internet can be the key to more and better educational and business opportunities, aside from the just better social interaction factor.

Guide to Set Up Wi-Fi

Guide to Set Up Wi-Fi

If you are thinking of how to set up Wi-Fi Internet network at home, you need not necessarily call a computer technician. The task may seem confusing, but it is actually not. If you have the right equipment and some simple instructions, you can easily do the task yourself. There are some things that you would need for setting up wireless Internet at home. These things include a desktop or a laptop computer, a DSL modem, a wireless router, two ethernet cables, and internet access.

The first step is to make proper connections between the devices. Switch on the computer and the router. With the ethernet cable that comes in the router pack, connect the internet port situated behind the router to the modem. Take another ethernet cable, and insert its one end in the LAN port on your notebook computer or PC. The other end of this cable should go in the WAN or WLAN port on the router.

The router pack will also include a software CD, which you need to install on your computer system. Follow the installation guidelines as they come on the computer monitor. The next step is to configure the router. This is supposed to be done by typing the router’s IP address in the URL field, and hit ‘Enter’. The appropriate IP address would generally come along with the router. However, if you do not find it, you can enter ‘192.168.1.1’ as the default address for a majority of routers.

You would be required to key in the user ID and the password for your particular router model. This information will also be available in the router manual. But if you cannot find these login credentials, you can visit ‘routerpasswords.com’, enter in your router’s model number, and get the details. Make sure that the wireless connection button on your laptop or desktop computer is switched on.

You now need to configure the Service Set Identifier (SSID), which does the job of recognizing your wireless network. The next step is to set a WEP or WPA password, which you need to use during logging into the wireless Internet network. Also, set up an administrative password that will prevent other users from tampering with the settings of the router. After this is done, click on save settings and ‘Apply’. You will be able to gain access to the wireless network after you restart the computer system. After rebooting the computer; click on the ‘Start’ icon, ‘Connect To’, and then the ‘Show All Connections’. If you have a wireless network set, its name will be included in the list at the top.

On the iPhone?

If you own an Apple iPhone and want to use Wi-Fi internet on it, you would need to do some settings. The first step is to go to the home screen and select the ‘Settings’ option. On the settings page, choose the Wi-Fi option. After doing so, it would take you to a page where you need to turn it on. You may select from the available networks in the list or choose another network.

If you want to choose another network, select the ‘Other Network’ option. When on the ‘Other Network’ page, a keypad will be displayed at the bottom of the screen, which you have to use to enter in the name of the wireless network that you want to join. If you want to assign a password to the new wireless network, you need to select ‘Security’ from the ‘Other Network’ page, and then ‘WPA2 Enterprise’. Tap on the ‘Accept’ button that comes thereafter. You can now put in the username and password on the ‘Other Network’ page. After all the configuration is done and all is set, on the upper left hand corner of the home screen, you will be able to see a Wi-Fi network signal indicator.

On the BlackBerry

The setup process in a BlackBerry mobile phone is somewhat similar to that in an iPhone. If you have a Wi-Fi compatible BlackBerry, select the ‘Manage Connections’ icon on the home screen. Then select the ‘Set Up Wi-Fi Network’ option, and click next. You would have two options, like ‘Scan for Networks’ or ‘Manually Add Network’. For an easy configuration, it is better to choose ‘Scan for Networks’. Choose from any of the available networks found, and enter security credentials if needed. After you select the ‘Connect’ option, the setup will be complete, and you will be able to use the selected wireless network.

On the Smartphone

Setting up a Wi-Fi on your smartphone (or connecting your smartphone to your already existing connection) is very simple. It gives you access to the internet without using your data plan. Remember to have the name of the network and the password. Then, switch on the Wi-Fi on your smartphone. From the wireless connection settings of your phone, search for the network name of the connection. After this, enter the password to connect to the network.

I hope after reading this article, you have understood how to set up Wi-Fi in your home, on an iPhone, on a BlackBerry PDA, or any smartphone.

Long Range Wi-Fi Adapter Ideas

Long Range Wi-Fi Adapter Ideas

Making use of a Wi-Fi adapter can solve many of your connectivity problems if you are unable to get a good signal from a Wi-Fi hotspot nearby. These come in handy when the hotspot is nearby, but for some reason you cannot move in a bit closer. With the help of an adapter you can get a stronger signal for wireless Internet access, and this is something that is both helpful and beneficial in many different ways.

Setting up such an adapter is as simple as it gets for you. All you need to do is buy one. You will get an installation CD, and this will contain all the software and drivers that you will need to make the device work for you. All you will then need to do is install the software and the drivers on your machine, connect it to the USB port, and it will be ready for use.

Product Review

Wi-Fire is said to be one of the best long-range adapters around today, and this can increase your signal strength significantly. Not only will it give you greater range while connecting to a hot spot, it will also increase the number of available hot spots that you can connect to. The routers that require passwords will ask you for the same, whereas unsecured ones will simply connect automatically. Needless to say, this will be highly beneficial for you.

Additionally, the wire connecting the device and the USB port can range up to 50 feet, and this adapter can then be placed anywhere you like. You can either attach it on the top of your PC, or you can place it near a window or any other place. This will give you greater room to maneuver. It is claimed that this device will increase your signal strength by at least 200%, and will also provide you with 3 to 5 times more wireless network connections than you would see without it.

You must strongly consider using these long-range adapters if you are facing connectivity issues while carrying out wireless networking. The advantages that these will give you, make it a very valuable and essential product.

Ways to Boost Wi-Fi Signal on Laptop

Ways to Boost Wi-Fi Signal on Laptop

unduhan-9We live in an unplugged world today; thanks to the developments in radio communication technology. Wired Internet seems like a thing of the distant past, as most of us increasingly prefer opting for wireless Internet access. Modern wireless networking systems are easy to set up and manage. One of the major problems encountered by most wireless Internet users is a weak Wi-Fi signal which reduces data transmission speeds, causing connectivity problems. In this article, I share some tips on how to boost Wi-Fi signal on laptop computers.

The Wi-Fi signal is a radio wave, which gets weaker with increasing distance of travel. The wireless router is the transreceiver, that is the source of the Wi-Fi signal and your laptop’s wireless adapter is its receiver. The reception of the Wi-Fi signal is therefore dependent on the initial output power at the router’s end and the distance between the router and the adapter. Let us see how to boost your laptop Wi-Fi signal by tweaking certain settings and adding some new equipment.

How to Boost Wi-Fi Signal on Laptop Computers?

I faced a problem with my wireless network some years ago as despite a high bandwidth and state-of-the-art router installed, I used to receive a very weak signal on my laptop. I decided to look into the problem and study ways in which the Wi-Fi signal can be boosted. With some modifications that I learned about through my research, I was able to boost the Wi-Fi signal beyond its existing limits. Whatever I learned about how to boost Wi-Fi signal for laptop, I share in the following lines.

Upgrade Router Firmware
One of the first things that you need to do is check to see if your wireless router’s firmware is the latest one. If you find that it’s outdated, get the latest version Updating the router firmware can take care of some of the software issues that can bring down strength of the Wi-Fi signal. For boosting Wi-Fi signal for laptop, make sure that you install the latest driver for your wireless adapter.

Increase Wi-Fi Router Output Power
One way of boosting the Wi-Fi signal is increasing the output power of the wireless router. Refer to the router manual to determine the procedure for increasing the power output of the router. When the power of router’s output signal is enhanced, the Wi-Fi signal reception on your laptop will automatically improve. If you ask me how to boost Wi-Fi signal on laptop, most economically, increasing router output power is the best choice.

Use a Wi-Fi Signal Booster Antenna
You can install a Wi-Fi signal receiver booster antenna to the laptop, which will certainly improve the signal reception and your download speed will certainly be boosted. Check out antennas which offer a high gain and reduced noise levels.

Change Position of Wireless Router
Simply changing the position of your wireless router can boost the Wi-Fi signal reception of your laptop. Physical constraints like walls can damp out the Wi-Fi signal. So position it in such way that the signal is least obstructed by such physical barriers. A change in installed position will certainly boost the Wi-Fi signal strength.

Use a Wi-Fi Signal Repeater
If you need the Wi-Fi signal to be receivable over large distances, you need to have a Wi-Fi signal repeater installed. These devices receive the original signal from the router, amplify its strength and then retransmit it over longer distances. Use of long range Wi-Fi repeaters will certainly help in improving Wi-Fi reception.

Attach a Wi-Fi Range Extender Antenna to the Router
Another simple way of enhancing reception of your router is by attaching a Wi-Fi signal booster. Once you attach an external wireless signal booster, the coverage range of the router will certainly increase, providing better wireless Internet access. Signals boosters for Wi-Fi are available in all the major electronics stores.

Buy a New Router
Wi-Fi antennas and signal boosters can substantially increase the range of your wireless network. The last option of course is to buy a good router, which provides greater signal strength and high transmission speeds. The latest 802.11n based routers offer dual band transmission and transmission speeds in excess of 450 Mbps, which can certainly boost your laptop’s Wi-Fi reception.

Hope these tips on how to boost Wi-Fi signal on laptop computers help you improve your wireless Internet access experience. If you use a home wireless networking system, I suggest that you go for the best 802.11n router, which will not only provide you with longer range, but it will also enhance the data transmission speeds over the network. Make sure that you follow all the steps to secure a wireless network, as enhanced range makes your network vulnerable to external hacking attacks.

Ideas to Clean a Dirty Cell Phone

Ideas to Clean a Dirty Cell Phone

unduhan-8Right from the moment we wake up, to the moment we fall asleep at the end of the day, we continuously use our cell phones! Which is a lot of usage for any gadget. If you pay attention to the way you handle your cell phone throughout the day, you will be amazed. The amount and variety of surfaces that we touch before touching our cell phones without washing our hands every time, is cause for party for the bacteria breeding on the surface of our extremely unhygienic and disgusting phones.

The cell phone, I’m sure you have noticed, heats up if you use it for too long. And then we put it to our ears and have hour-long conversations. If you cast back your mind to school, you may vaguely remember being taught that certain conditions are very conducive for breeding of bacteria, heat being one of the major factors. So as you gossip and giggle with your phone stuck to your ears, the bacteria are multiplying, and fast. When we are done, we wipe the sweat off the phone and put it away. Gross! You may seriously want to clean your cell phones. I’ll tell you how to do it, if you don’t already know.

Cleaning Your Cell Phone

Here is a simple step-by-step process for the best way to clean your cell phone.

Step 1: Switch off your cell phone, and disassemble it. This makes the cleaning work much easier. Separate the case, keypad, battery, faceplate, and whatever else you can, without damaging the phone or breaking it.

Step 2: Make sure that your battery has been removed before any moisture comes in contact with the cell phone. If the moisture leaves any mark in the area marked by dotted lines where the battery is supposed to be, then your complaint will be dismissed as water damage, even if this happens within the warranty period. The warranty doesn’t cover water damage, besides which it cannot be rectified. So make sure that you keep the area that is supposed to be dry, really dry.

Step 3: Take a cotton swab, microfiber cloth or some wireless wipes, distilled water and some rubbing alcohol. Dip the swab/ cloth in the alcohol and wipe the different parts of your disassembled cell phone. The swabs are used for cleaning the keypad, and the microfiber cloth and the wireless wipes are used to clean the screen of the cell phone. Rubbing alcohol is useful for old hard plastic screen phones, whereas the distilled water is useful for the newer screens and metal trims on the phone, as well as the camera lens.

Step 4: Make sure that you wipe the camera lens off with a dry swab immediately, so that the water drying on it doesn’t leave a residue on the lens. This works great for smartphones and blackberry phones. The disinfectants/ cleaning chemicals found around your house are too harsh for these phones, so do not use any of those chemicals. Do not spray any chemical directly on the screen of your phone, else that will be the demise of your screen. You will have to replace it with a new one, which can be very expensive.

Step 5: Rub lightly so that the coating is not affected, and keep a little space from the edges so that the alcohol or distilled water doesn’t seep inside the phone and damage it. When cleaning the inside, make use of dry swabs, and in case of stubborn, dried-on dirt, wet the swab very slightly and wipe. Dry with a dry swab pronto, to make sure the moisture doesn’t go where it isn’t supposed to. If the moisture seeps in, it will short circuit your cell phone.

Step 6: If your screen is cracked, leave the screen protector on, lest the water seeps in through any crack that has formed. Also, do not go overboard when one swab comes away black, and keep scrubbing vigorously till you hear squeaking sounds. You will end up scratching your phone and removing the clear coating or oleo phobic coating which is present on a few models of smartphones.

Step 7: Replace the screen guard with another one as soon as the screen dries, if you had to remove it while cleaning. Once you are done with the phone, make sure that you clean your phone case in a similar manner. Use the rubbing alcohol and clean till the swabs come out almost clean. Leather cases have their own special cleaners which will clean and moisturize the leather.

Step 8: Clean the USB connectors (places where the charger, headphones, etc., are connected to the handset) with a brush dipped in rubbing alcohol. Not soaked in it, just slightly dipped. Let the phone dry thoroughly before you reassemble it, especially the areas near the location of the battery. Use another dry swab if you think some moisture is left in the phone. This is how to clean your cell phone. Once you are sure that the phone is really dry, then reassemble it and switch it on.

Make sure that the isopropyl alcohol you use is as close to 100% as possible. If you do not get 100%, try to get 98% or 97%, which is more easily available and is the best for cleaning.

UV Cell Phone Sanitizer

The UV cell phone sanitizer is a new cell phone cleaning gizmo, that can be used for cleaning almost all types of cell phones. It claims to clean 99.9% germs off your cell phone, making it safe and clean for use, in under a minute. All you have to do is, keep your cell phone inside the device and it will do its work. It bombards the cell phone with extremely powerful, shortwave UV radiations, which kill almost all the harmful viruses and bacteria thriving and breeding on the phone. You don’t have to do anything. But till the time you lay your hands on this very useful device, clean your cell phone manually, as per the instructions given above. You may end up doing yourself a favor, and save yourself from harmful diseases caused by the viruses and bacteria found on cell phones.

How would the idea of continuously rubbing your face against the toilet seat, while having a conversation with someone, appeal to you? What you are doing right now while talking with the phone glued to your ears, is more harmful and gross. It’s really not very difficult or time-consuming to clean your cell phone every few days. 15 minutes every week will give you a cleaner and safer phone, so why not invest this time? If you do, there is no need to imagine a toilet seat when you are talking on the phone. A very useful tip would be to try to use the handsfree as much as possible, instead of placing the phone on your ear and cheek. This will prove beneficial in the long term, if you are a regular user of the cell phone. You also get ready-made cell phone cleaning kits in the market, and you can just buy one. Do what you can, to get your cell phone clean. You will thank yourself later. Next time someone asks you how often do you clean your cell phone, you better have a good answer!
