I've had my Inspire for about two months now, with no problems with the wifi whatsoever. Earlier today I left home, used some data while out and about, and when I came home, my Inspire will not connect to my wifi. When I go to 'settings', it shows that it is scanning, connecting, obtaining the wifi address, then then it disconnects. It keeps repeating the cycle. I've shut it off, I've taken out the battery for a moment and put it back in, and turned it back on, I've tried 'forgetting' the network and then re-entering. I also checked my 'sleep' settings and it is set to 'never'. Still the same problem. This is the first time something like this has happened. I've had the Gingerbread for a couple weeks now and it's been working fine and haven't had a problem until now.
I don't believe it is my router; my computer and my iPod both connect with no problems at all.
