Networking freezes... disconnects... network adapter disables itself... computer won't shut down...

I recently installed Windows 7 Professional.
Ever since I've been having wireless networking issues.
I lose connection after a couple of minutes after starting up my computer.
The adapter disables itself often, and the Network and Sharing Center freezes.
When trying to let Windows diagnose the problem, all it ever does is try to reset the network adapter, and this process usually freezes as well.
The only way to get it to work again (only for about 10 minutes if I'm lucky) is to restart the computer....
which
doesn't work, either.
After the "Windows is shutting down" screen my monitor goes blank, like it's supposed to, but Windows never restarts, yet the power indicator on my tower remains lit.

This was a clean install of Windows 7 Professional.
The only software I have installed so far are Mozilla's Firefox and Thunderbird, and Kaspersky Internet Security 2010.
The very first thing I did was run Windows Update; I had to run it several times before
I got lucky and remained connected long enough for it to finish downloading.

I tried the tips in similar threads about starting up in safe mode; didn't help.

I had this same exact problem with Vista Home Premium, which is a major reason why I upgraded to 7 Pro.

Hi angelxero,

Thanks for posting.
What is the make/model of your computer and/or the make/model of your wireless adapter? Have you gone to the OEM site to see if they have updated drivers for Windows 7? Also, what encryption do you have this issue with? Try putting the encryption
to none on the router and see if you still have the issue.
Please keep in mind that after you take off the encryption it does leave your network unsecure, so only do this to test with and immediately re-enable the security on the router after you have performed
the test.


Hope this helps!
