This problem only happens at my house, but no other devices have these connectivity issues.
I have to keep toggling airplane mode on and off or manually reconnecting to the Internet every 30 seconds or so. If it says connected for an entire minute, it's a miracle.
Also when I try to manually reconnect, it usually asks for my wifi password, but if I cancel and try to reconnect a couple more times, it will connect without re-entering the password. 
Is there any way to keep the wifi from disconnecting so often??
