I'm travelling around southeast Asia and I am in Laos now. I have disabled mobile internet connect and have been using just Wifi for internet connection. All of a sudden wifi stopped working. I can see the networks, have the option to connect and give a password but then it stops there. it will say 'authenticating' or something like or even "connecting" but never establish the connection. what gives? I would love to get this to start working again, any suggestions would be greatly appreciated, thanks.
