Few days ago the wireless in my son's Dell Inspiron 620 went bad. It does connect to my old router (WEP), but speed is terrible and connection goes bad after some time. I can also see my modern router and enter the key successfully (WPA2), but it won't connect. Connection to both routers went well for months before, and still goes well from all other devices in the house.

I read the issue with McAfee that was posted late August and followed the steps. Connection in safe mode didn't work. Then I removed McAfee from the PC, no difference. Then I restored the PC to a couple of days before the issues began, removed McAfee again (as it came back through the restore), no difference.

I reinstalled the drivers of the Dell wireless card, no difference.

I'm at a loss now, any more tips?
