Because I have a switch to disable the Wifi power, this seemed easier/safer, and it worked. thanks, Solution: remove whatever "preferred networks" are displayed in wireless netwok card's property page, n click ok. happens when u switch to a new router or use a new different SSID.cheere Hadn't read all solutions so I apologize if I'm repeating someone but all I did was go back to Belkin router setup utility, or (192.168.2.1) and clicked "wi fi protected setup".Now click on the Wireless Networks tab and select the network in the list at the bottom.

I am using the Windows Wireless Connection Manager. On a couple of occasions I've seen that particular AP (don't know what firmware) suddenly stop attempting to authnenticate clients (it never sends any RADIUS requests) and power-cycling the AP "fixes" the issue.

Then, I selected disable at the "wi fi protected setup (wps)" option.

This seemed to work for me after I disconnected from my router and reconnected again.

In the next window click on the "Authentication" tab, Make sure "Enable IEEE 802.1x...." checkbox is UN-Checked, the rest of this window should be greyed out.

If your network is Encrypted go on to step 6 otherwise Click ok and try to connect to your network again.
