AT&T HTC Inspire Phone home WI-FI not connecting

[vjy111]

I am having a htc inspire phone(last 2 years) and everything was fine. Suddenly for the last week or so, the home wi-fi is not working. I tried restarting, re-connecting, but it does not work. Everytime, it connects and then immediately disconnects. I am not able to use it at all.

I have not tried to connect to other networks though. Any ideas?

Thanks.
