mobile

I recently received the OTA update from T-mobile to jellybean. When I tried to turn on wifi this morning it would not connect and then said "error" when seeing it in the settings menu. After trying to reboot my phone it now automatically tries to connect to wifi eventually resulting in an error, and will turn off and then reboot any time the screen turns off whether it be manually hitting the power button or letting the screen time out. Is there a process or app I can force close/disable to reset the wifi or am I doomed to a factory reset? Thanks
