Help, I cant connect to any wireless networks!

I have a Samsung N148 notebook and windows 7. I have been connecting to wireless networks for the last few weeks and all of a sudden, out of the blue, every time i try to connect I get a "Windows was unable to connect to *network name*" message. I have tried rebooting both laptop and wireless router, I have un-installed the drivers for my Atheros AR9285 Wireless Network Adapter and reinstalled the most current i could find off the net. I have tried starting in safe mode with networking enabled and i have tried turning off my virus protection. I have tried all the windows diagnose options i could find and still no luck. Please help. Thanks.

You state you can't connect to any wireless networks but you only give an example of the one with your router. Have you tried other wireless networks as well? Ordinarily I'd suggest doing the actions you've already done but since you have w/o resolution the one action I will suggest is to restore your PC to a date about 3 weeks ago when things were working it is possible an update has messed up things and a restoration may prove useful in restoring your wireless ability and then keep a close eye on your updates to try and find what caused it.

It has resolved itself for some unknown reason. I just dont understand computers sometimes. Cheers for the reply. :)
