Thanks to malwarebytes I recently I cleaned off a nasty virus from my laptop. Ever since getting rid of the virus though windows networking services no longer detects available wireless networks. The preferred networks list is always empty and if I try to add a new one it doesn't save the information. The wireless card IS on and I've stopped and restarted all pertinent services pertaining to the wireless. I have also updated the wireless card drivers. I know the wireless networks are out there because the toshibas configfree program detects them (but won't let me connect to them). I have had no conflicts in the past with the toshiba and microsoft products together. The only thing I have not done is uninstall and reinstall the Windows Networking Service.

Based on some other threads in this forum here is some additional information:

[indent]Microsoft KB article to reset TCP/IP
One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become corrupted. If you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it.
Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state by using the NetShell utility (netsh)

I've done what you've suggested and I've also updated malwarebytes and reran it but so far nothing is working. My laptop connects to the internet fine with a wired connection but if I try to use the wireless windows is still not detecting any wireless networks in range, even when they do exist. I am not sure what the toshiba program is using to connect, maybe its connected directly to the antenna. At this point I am thinking that the virus did something to the wireless network card. I am just clueless at this point since I've done everything I can think of to get the card detecting again.

Try going to the Toshiba site and getting the correct driver for it and re-installing it.

The toshiba site is where I downloaded the updated driver. I'm stopping by best buy today and picking up another card to see if the card is indeed the problem since dang near everything else has been ruled out.
