Thanks for the advice.
For my case installing wififofum worked!! I was having the same issues, my wifi would not connect to any hotspot. It was working fine throughout the day picking up different hotspots at the store and driving around.
The odd thing that happened to me, was I talking on the phone, and sending an email at the same time when all of a sudden my phone drops the call, screen freezes up, and I had to shut it down (not a hard reboot). When the phone finally turned on it was having a hard time connecting to AT&T, but eventually did.
Of course at that moment I didn't think of checking for wifi, but 15 minutes later when I made it home, it was not connecting. I did everything other folks have posted reset networks, blah, blah, blah. I was about to believe maybe the chip fried till I saw your posting and figured why not buy the program. Thanks for the advice SO SDD. I'm going to keep my fingers crossed and hope I don't have one of the bad wifi chip batches like others have posted.

Good luck out there.
