Got mine on release day and wifi works great at home. However at work, it disconnects and refuses to reconnect automatically and even if I try to force it. I turn off and off wifi but still no luck. My work wifi does not require any passcode or login (we have our own building away from others and you still have to VPN in to access internal network but access to the public internet is fine without VPN). My work provided iphone 5's wifi works perfectly fine.
