Hi, I searched the forum for a similar problem but have not found and answer yet. First off , I would like to say that I don't have a data plan as I don't need it, I only rely on wifi to get data. At first I think the wifi was working great. But after I upgraded to gingerbread my wifi will stop working after maybe 2 minutes. If the phone is not sleeping I can go to wireless settings only to find that under WiFi it says : error. I cannot turn it on again. If I press the power button my screen becomes black and won't turn back on until I remove my battery and start the phone back again. This is very annoying. Does anybody knows what I could do to fix the problem ? I tried using Fix my Wifi app and did a reset to factory settings.
