My mother's computer has a wireless router. I got this adapter several months ago, but suddenly it just cut out. I tried re-installing the software, restarting my computer (it has helped in the past) and connecting to various connections, but nothing is working. All the lights on my router (Linksys) that are normally on are on and my older brother, who has a laptop, is surfing the web with no issues from this router.
On your computer with the wireless adapter, can you "see" the router, and are unable to connect to it, or can you not even see it?
If you can see the router but can't connect, make sure you input the security key and other information correctly. You could try deleting the connection on your computer and re-connecting as a new connection.
You could also try going into the router's settings from a computer that can connect to it and making sure MAC address filtering or any advanced security options didn't get turned on somehow. You can do this by typing the router's IP address into your web browser (which is typically 192.168.1.1, but you can find it by typing "ipconfig /all" at the command prompt and looking for the entry for the router) and entering your username and password.
Hope that helps! If you still can't connect, do you get an error message when you try, and if so, what is the message?
If your computer has a wireless network adapter, Windows will automatically detect wireless networks in range of your computer. You can see a list of wireless networks that Windows has detected in Connect to a Network.
Open Connect to a Network by clicking the network icon ( or ) in the notification area.
If Windows doesn't detect a network that you think is in range of your computer, it could be because of one of the following reasons:
The wireless switch on your computer is turned off.
Many laptops have a wireless switch on the front or side of the computer. If your computer has a switch, make sure it's turned on. Some computers also use a function key combination to turn the switch on or off. Check the information that came with your computer for details on locating the wireless switch.
Your computer is too far from the wireless router or access point.
Move your computer closer to the router or access point. If the 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 a 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 unplugging it, waiting at least 10 seconds, and then plugging it back in.
