I'm not sure what to do. when i tried again it just hanged there.

Update: I unplugged the router and waited 30 seconds and....it worked again! thanks everyone for chime-ing in :)

Alright, testing the hotspot, and it works. (but that must mean they're is something wrong with the network perhaps? or i guess the drivers? because the home network still isin't working.)

im sorry to sound stupid, but where would i find an ethernet cable? would it be connected to the router?
