Haha, I running T1, So I don't know if this will be the same. All I did, was unplug my router and modem. Plug the modem back in, and if yours has all the lights, let it go through it's sequence. Then plug the router in. When you unplug them, leave them out for a minute or two.
Wow, I just realised how much of an idiot I am, But i'm not going to delete all that up there, maybe it will come in handy
