Sounds like a wifi issue. Is there a reset option? If yes try resetting it. Wifi is not super reliable generally speaking & cannot handle high volume connections & bandwidth too well compared to normal connections.

I tried powering off, then resetting but still cant find the server. Its odd, it was working for months then all of a sudden it said can't find server. Not sure if you would know but there is a new update version for my itouch, do you think if i install the new version, it would correct the problem? The new version only costs $10 but only want to install if it will correct the wifi problem..
