Wifi worked and then stopped working
 

Hi,

I just picked up a 770 and have been playing around with it for about a week. I updated with the latest software (not sure if this is firmware or what) and the 2006 OS update a few days later. I have no other additional software loaded.

I set it up using WPA-PSK with no broadcast connecting to D-link router. It worked fine and stable for the first few connections, but now it won't connect any more. I rebooted it a few times with no luck. When I try to connect, it appears to go through and notifies me that it's connected, but now I have a question mark on the connection logo instead of an antenna. The IP address is not in the range assigned by my router. Any ideas?

Thanks,
Pete
