Why is my wireless signal strength so low?
If a wireless network has a low signal strength, the transfer of information across the network could be slow or you might not be able to access certain parts of the network. Here are solutions to some common problems with low wireless signal strength:
-
Your computer is too far from the wireless router or access point.
Move your computer closer to the router or access point. If your computer is portable, try moving it around to determine the range of the wireless signal and the best place to use the computer.
If you can't get closer to the router or access point, consider buying and installing an external antenna for your wireless network adapter. Many wireless network adapters are set up so that you can attach an external antenna to them, which provides better reception than the built-in antenna. Check the information that came with your wireless network adapter to see if you can install an additional antenna.
-
The wireless router or access point is turned off or isn't working properly.
There are two things to try:
Make sure the router or access point is turned on and that the wireless signal light is illuminated.
Reset the router or access point by turning it off, waiting at least 10 seconds, and then turning it back on.
If you don't own the access point or don't manage the network, contact the network administrator.
-
There is interference from other devices.
If you have 802.11b or 802.11g network hardware, it uses the 2.4 gigahertz (GHz) frequency. Other devices that use this frequency include microwave ovens and cordless phones. If you have 802.11a network hardware, it uses the 5 GHz frequency. Some cordless phones also use this frequency. These devices can cause interference between your computer and the network.
There are two things you can try in this situation:
If any devices like these are near your computer, turn them off temporarily or move them farther away.
Change the router or access point settings to use a different wireless channel, or set the channel to be selected automatically if it's set to a fixed channel number. Sometimes one wireless channel is clearer than others. In the United States and Canada, you can use channels 1, 6, and 11. Check the information that came with your access point or router for instructions about setting the wireless signal channel.
-
The network you're looking for is set to not broadcast its network name (SSID).
Wireless routers and access points can be set up so that they don't broadcast the network name. In this case, you can't detect that the network is in range (in order to connect to it) unless you've previously connected to the network or you manually connect to the network using the service set identifier (SSID). To connect to a network that's not broadcasting, follow these steps:
Open Connect to a Network by clicking the network icon (
or
) in the notification area.
Click Unnamed Network, and then type the network information.
The network will be added to your list of networks and will be available to connect to in the future when your computer is in range of the network.
8 Ways to Fix a Weak WiFi Signal
In just a decade, WiFi signal has become almost as essential as food, water, and shelter. A weak signal can be a modern day nightmare. Poor loading times and lost connections can test your patience while browsing the internet. This guide will help you understand why your WiFi signal can become weak and how to improve it cheaply.
Get a Modern Router I just moved and recently got cable. The Internet installer laughed, pointed, and mocked my wireless B router. I had no idea I was using caveman technology. Apparently WiFi speeds are much slower on wireless A, B, and G routers. Wireless N is all the rage when you want the fastest speeds possible. You will need both an N router and an N card in your computer for maximum speed.
Check for Router Updates While not as annoyingly frequent as app updates, router manufactures sometimes issue stability resolutions via driver updates. Go to the manufactures website to download all new maintenance updates and changes.
Don’t Hide Your Router Routers can be disgusting looking things and your first instinct is to hide it behind your television or in a box. Resist that urge as a wide open router, clear of obstructions and with antennas pointed upwards, will perform better. Make sure the router is relatively close to where you’ll be using the WiFi.
Change WiFi Channel Wireless routers broadcast on numerous different channels, similar to radio stations. It can cause buildup and static if a lot of people are on the same channel. Newest routers feature automatic channel selection. If you have an older model, test and try another channel to see if you experience less interference.
Use the free Wifi Analyzer Android app to pick the best channel for your router. The app works great by scanning immediate channels and helping you find a less crowded channel. Move the router around the house to maybe find an even better channel.
For iPhone users, check out the $4 WiFi Explorer app to help find the right channel. Quickly identify channel conflicts, signal overlapping or configuration problems that may be affecting the connectivity and performance of your home or office wireless network. Get an insight into network details like name (SSID), MAC address (BSSID), device manufacturer, signal strength (RSSI), noise, channel, band, security configuration, supported data rates and much more.
Use Two Routers Even if you have a fast connection, too many electronics can often overwhelm your WiFi. Using two routers can be very beneficial. Take advantage of the free (or cheap) router your cable provider gave you and use it as an access point. This is useful for a home entertainment system or a game console that can be constantly plugged in via Ethernet cables, leaving the WiFi for your smart phones and laptops.
Kick Your Neighbors Offline Your freeloading neighbors will now have to search elsewhere. WPA encryption is much harder to hack than WEP, so go with WPA for your password. You can check if someone other than you is using your WiFi. Make sure your network, gaming console, and everything else using the Internet is turned off. Look to see if the wireless light is still blinking. If so, you may have a leech (or worse, a potential hacker) to deal with.
Use a program like MoocherHunter, which is used by police in some countries, to find real-time users of your wireless network.
Buy a Range Extender If your WiFi is having trouble reaching all ends of your house or large office, consider buying a range extender. A basic $50 extender should do the trick. This probably won’t make your WiFi any faster, but at least you’ll have Internet access in the basement and attic. You can also create a DIY extender, but I am certainly no expert on that.
Do a Speed Test If you have followed most of these steps, and still don’t see an improvement, check out what kind of speeds you are getting at Speedtest.net. If the speed is significantly lower than what you are paying for, discuss this matter with your cable provider. Sometimes cable providers throttle down your Internet performance so they can hit you with a bandwidth usage fee. Research your provider and consider switching to a company who doesn’t limit your Internet speeds.
There’s plenty of more tricks and tips for faster WiFi speeds, like using a beer can. Do you have any WiFi hacks to share with the class?
How to resolve poor or no signal from a wireless router
Resolving poor wireless signal
There are a few factors why your wireless device is getting low or poor signal from the router. This article will guide you on how to resolve these issues.
Low or poor signal is mainly caused by six (6) major factors:
• Distance problems• Physical obstructions
• Wireless interferences
• Transmit rate on the wireless router
• Outdated firmware on the router
• Power outage
Distance problems
Wireless devices have limitations when it comes to their signal range. For devices running on 2.4 GHz, the range can go up to 100-150 feet (30-46 meters). If your wireless network devices are too far from each other, consider relocating the devices. Remember that distance is directly proportional to signal strength. The farther you are from the access point, the weaker the signal.
To check if you’re getting a stable connection, perform a continuous ping. If you’re getting replies most of the time, this means the connection is stable. If time outs are occurring frequently, the connection is not that stable. For instructions on how to perform a continuous ping on your computer, see the article below:
Pinging the Linksys router

To get the best connection, you may need to find ways to move your computer closer to the center of the router’s range. When choosing an area where the router will be placed, ensure that it is well ventilated.
Physical obstructions
Wireless networks are also susceptible to obstructions that may lead to low signal. Oftentimes, the signal gets reflected, refracted, or absorbed by the obstruction.
Common obstructions are:
• Cabinets or drawers
• Mirrors, Glasses
• Metal Objects
• Thick walls and ceilings
• Aquariums
If you have any of these objects between your wireless adapter and access point, consider relocating your access point somewhere high to get around the obstruction.

Routers have a default broadcast range that is dependent on their wireless networking standard (Wireless -B, -A, -G, -N, -AC draft) and the wireless signals broadcasted by the router may not be able to completely penetrate thick walls and other common obstructions.
Also, you may use a Linksys range extender or Powerline to boost the signal of your router if you have a big area and there are a lot of obstructions between your router and the wireless device. For more information about how to expand your network using Powerline adapters, click here.
Wireless interferences
Common sources of interference are:
• Neighboring wireless networks
• Microwave ovens
• 2.4 GHz cordless telephones
• Bluetooth® devices
• Wireless baby monitors
To solve the problem, change the channel and SSID on your access point. Preferred channels to use are 1, 6, 9 and 11 since they’re considered as non-overlapping channels.
The 802.11b/a/g/n standards use the 2.4 Gigahertz (GHz) band. With this frequency, 802.11b/a/g/n equipment may encounter interference from microwave ovens, cordless telephones, Bluetooth® devices, and other appliances using the same band. To learn how to change your wireless router’s channel, see the article below:
Changing the wireless channel on a Linksys router
You can also select the 40 MHz channel width on your 2.4 GHz network to improve the performance of your Wireless-N network. However, this is only advisable if you are in a location less crowded with wireless networks. It is also important to note that in order for your wireless devices to connect to the network, they need to have a Wireless-N network adapter that is compatible with the 40 MHz wireless channel. The latest versions of Linksys Wireless-N adapters can connect to a 2.4 GHz network with 40 MHz radio band.
QUICK TIP: The Linksys Smart Wi-Fi Routers have the 40 and 80 MHz Channel widths in the 5.0 GHz network.
If you are not sure about the settings, it is best to leave it at its default settings. The channel width is set to Auto by default. This automatically defines the best wireless channel for your wireless network.
Transmit rate on the wireless router
Changing the Transmit Rate on the router allows the device to work at a specific speed for wireless transmissions. The default Transmit Rate is Auto with a range of 1 to 54 Mbps.
The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds or keep the default setting, Auto. This will allow the router to automatically use the fastest possible data rate and enable the Auto-Fallback feature, which will negotiate the best possible connection speed between the router and a wireless client.
NOTE: If the transmit rate on the router or the adapter is not set to Auto, the Auto-Fallback feature will be disabled. If the Auto-Fallback is disabled, you will not be able to experience the maximum range of the wireless router as it will not be able to adapt to the environment’s condition.
Linksys does NOT recommend changing the transmit rate of the router other than the default value since it will shorten the range of the wireless network as shown in the sample diagram below.

If you can't get connected into your router after changing the transmit rate to AUTO, try to change the transmit rate manually by using the router’s web-based setup page. You can do this by accessing the router’s web-based setup page, then click on Wireless > Advanced Wireless Settings. You can set your preferred rate on the Transmission Rate drop-down.
Outdated firmware on the router
Outdated firmware on the router can sometimes cause connection issues in your network. To fix this, you need to upgrade the firmware of your router. To properly do this, click here. For a video on how to upgrade the router’s firmware, click here.
Power outage
One factor that may also trigger the poor performance or loss of wireless signals coming from the router would be power/electricity interruptions. If you are not able to acquire any wireless signal after a power outage, you may powercycle the router by unplugging and re-plugging the power cord from the power outlet for 10 seconds.
However, if the powercycle still does not resolve the problem, you may need to reconfigure the wireless settings of your router. Refer to the links below for more information:

How Can I Make My Computer and Phone More Friendly to Use at Night?
The thing that makes your eyes hurt so much (and keeps you awake at night) is the blue light coming out of your screen.
Just like wearing orange goggles when you go skiing, the best way to alleviate the pain of nighttime screen usage is not just to dim the brightness, but to lower the color temperature.
Our favorite way of doing this is to use an app called F.lux, which will automatically detect when it's nighttime, and adjust the temperature of your screen accordingly. You can choose from one of four settings that tweak how heavily it tweaks, the highest setting being a slight orange tint and the lowest setting looking like you're wearing rose-colored glasses.
F.lux is available for Windows, Mac, Linux, and jailbroken iPhones and iPads, so you can use it on nearly any device. If you're an Android user, some custom ROMs (like CyanogenMod) come with built-in filters that let you accomplish the same thing, though without as much control (and you'll need to root your phone before you can install them).

Top 10 Hidden Features in windows 7
Windows 7: The Top 10 Hidden Features
1. God Mode It may be hyperbolically named, but Windows 7's God Mode is indeed omnipresent. It conveniently puts hundreds of settings from all around the operating system all in one place.
To turn on God Mode,
create a new folder on your desktop--or anywhere you'd like--and name it:
GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}.
Don't include the final period. The resulting folder will contain 270 items, representing virtually every configurable option in Windows 7.
What is the importance of God Mode in Windows XP?
God Mode is a Windows OS feature that further enhances the ‘ease of use’ characteristic for all Windows XP users. God Mode is a folder that collects a comprehensive list of customization settings allowing you to change all your settings from one place. It is very simple to be enabled and pretty useful too, provided you tweak around things to suit your requirements. As you may have already guessed from its name, the mention of the God Mode actually creates a lot of anticipation for a user, and you actually start expecting grander features to explore. To meet up to your expectations, Microsoft has set this hidden feature, the ‘God Mode’, with a facility to access all of the operating system’s control panels from within a single folder. By creating the new folder in Windows XP and by renaming it with a certain text string at the end, you will be able to have a single spot to take care of multiple things including changing the look of the mouse pointer and creating a new hard-drive partition.
Following are the important roles of the God Mode in Windows XP:
Better multitasking
Avoids issues from cropping up
Frees up memory space
Better multitasking
Multitasking is the process of executing more than one task at a time. The God Mode in Windows XP helps you to multitask. Since you can do multiple things in one go, you save time, efforts and also increase your productivity. After you have enabled this mode, you will be able to access all the different settings from one place, this one common folder. You don’t require accessing the different folders every time you require a file stored in them. You reach this one place and you get everything here, neatly organized and settled.
Avoid issues from cropping up
The God Mode in Windows XP helps you to avoid the chances of issues cropping up in the system. Since this folder contains all the security options in the Control Panel, you could access all of them from this single folder. In the event of a situation wherein you are prevented from accessing particular files, folders, or an application, you can easily access this folder and reach the required files and folders.
Frees up memory space
Since this folder contains all the settings in the system, you could free up memory space by deleting the settings from its other locations. You don’t need to store all those settings in separate folders; easy access to just one folder will definitely do the trick here. You will further be able to speed up the system by organizing files in a single place. The processor does not need to access those settings from separate folders and thereby uses up less memory space.
How to enable the God Mode in Windows XP
To enter the ‘God Mode’, you will need to create a new folder and then rename the folder as: God Mode.{ED7BA470-8E54-465E-825C-99712043E01C}. Once that is done, the folder’s icon will change to look like a control panel and will contain all the control options that you generally require! That’s it.Isn’t this hidden Windows XP feature impressive? Enable your own God Mode in Windows XP today and see how you increase your productivity instantly. Dial our toll free number to let iYogi tech experts set up the God Mode in your Windows XP PC. We are available 24x7 and you can contact us as per your convenience?
2. Enhanced Calculator
Windows' built-in calculator hasn't really changed much over the years, but Windows 7's calculator has a few extra tricks up its sleeve, which you'll find under the View menu.
It can do myriad kinds of unit conversion (temperature, weight, area, and eight others), interesting date calculations, and even has worksheets to calculate a mortgage payment or a car's fuel mileage. It maintains a history of your previous calculations as long as the program is open.
3. WordPad's File Support
The built-in WordPad word processor in Vista is of limited usefulness because it only supports RTF (Rich Text Format) and plain text (TXT) files. In Windows 7, on the other hand, WordPad isn't quite as restricted.
Although Windows 7's WordPad still doesn't work with .doc files from Microsoft Word 2003 and earlier versions, it can open and save ODT (OpenDocument Text) files used by the free OpenOffice.org word processor as well as .docx files created in Microsoft Word 2007 or 2010. Although WordPad can't understand all the complex formatting (it will warn you of this upon opening or saving a file), it will still let you read the documents without having the native programs installed.
4. Reliability Monitor
When your system's acting flaky and you're trying to figure out what's going on, the Reliability Monitor may help. Search for "reliability" from the Start menu, and run View reliability history.
You'll get a graph of your system's "stability index" over a period of days and weeks (rated on a scale of 1 to 10). It displays which programs, Windows components, or miscellaneous items crashed on a given day, helping you identify problem items.
5. Problem Steps Recorder
When you need outside PC help, it's much better to let
them see for themselves what's happening on your system. But if remote
access isn't an option, the Problem Steps Recorder may be the next best
thing.
Search for and run "psr" from the Start menu. Click Start Record, and
the utility will record your activities through a series of screen
shots, automatically including captions that show exactly where you
clicked. You can also use the Add Comment button to highlight specific
areas of the screen and insert custom annotations. When you stop
recording, everything will be stitched together and saved as a Web
browser-compatible MHTML (MIME HTML) file, conveniently pre-ZIPped and
ready for e-mailing to your geek of choice.
6. Power Efficiency Report
If your Windows 7 laptop isn't getting the battery life
you expect—or it experiences power-related issues, such as the inability
to go into standby or hibernate mode—the problem usually lies with
incorrectly configured power management settings.
Windows 7's Power Efficiency Report can help you sniff out potential
problems. Type search for CMD from the Start menu, run it as an
administrator (right-click cmd.exe on the menu and choose Run as
administrator). From the command prompt, type powercfg –energy
(include the space) to scan your system, and after about a minute,
you'll find a file called energy-report.html in your \windows\system32
folder.
Copy the report to another location and open it (you'll get a file not found error if you try to open it from the system32 folder) for detailed information about what system devices or settings are throwing a monkey wrench into your power management. Get more details on the PowerCfg utility.
7. Pin Folders to the Taskbar
You already know that you can right-click your favorite programs and pin them to the Windows 7 Taskbar for easy access. Right? Although there's no such option for folders, there is another way to keep them close at hand on the Taskbar. Right-click any folder, drag it to an empty space on the Taskbar (or to the Windows Explorer button), and let go when "Pin to Windows Explorer" appears. Now when you right-click the Windows Explorer button, your folders will be accessible via the Jump List.
8. Wipe Free Disk Space08
It's no secret (or at least, it shouldn't be) that when
you delete files or folders in Windows, they're not actually erased—the
space they took up is simply marked as "available for use," which allows
the files to be recoverable (with the right software) until they're
overwritten with new data.
There is a utility built-into Windows (even XP Pro and Vista) that will
overwrite all the free space on a hard drive, insuring any files you've
deleted stay dead. Launch a command prompt and type cipher /w:X
where X is the letter of the drive or partition you want to wipe. Be
patient—the process can take a long time if you have a lot of free
space.
9. "Virtual" Wi-Fi
If you check out the network connections of most Wi-Fi-equipped Windows 7 systems (except those with Starter Edition), you'll notice an adapter called Microsoft Virtual WiFi Miniport adapter. This virtual adapter can act as a software-based access point; it takes a wired or wireless network connection and makes it available a separate wireless network.
This lets you create your own hotspot from whatever network you're connected to, which can be handy in many different scenarios, including when you want to connect multiple devices to a Wi-Fi network that charges for access. (Note: to take advantage of this feature, you'll need a copy of the free Connectify software.)
10. Hotkey a Window between Monitors
Want an easy and mouse-free way to move windows around a display or, better yet, between multiple monitors? When you press the Windows key + the left or right arrow key, the active window will move from its original position and anchor itself to the edge of the screen in the direction of the arrow, and it will do so across every monitor you have. Similarly, if you press Windows + SHIFT + left or right arrow, the active window will jump over to the same position on the adjacent monitor (so if you only have two monitors, it doesn't matter which arrow key you use).
Fix cannot view other workgroup computers in the network
You are working on a Microsoft Windows XP- based computer for which the following conditions are true:
The computer resides on a network.
The computer is a member of a work group.
Either no firewall is enabled or no firewall is installed on the computer.
The computer can ping other computers in the same work group. Also, other computers in the same work group can ping this computer.
NetBIOS over TCP/IP functionality is enabled.
In this scenario, you cannot view other work group computers on the network.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in Windows
To resolve this issue, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NetBt\Parameters
In the right pane of Registry Editor, delete the following values if they are present:
NodeType
DhcpNodeType
Note If the NodeType value is present, this value will override the DhcpNodeType value. If neither subkey is present and if no WINS servers are configured for the client, the computer uses b-node mode. If at least one WINS server is configured, the computer uses h-node mode.
Quit Registry Editor.
Restart the computer.
Try to view workgroup computers on the network again.
