U-verse gateway authentication failure
I was cleaning up some wires and unplugged my modem and when it was plugged back in I'm getting a gateway authentication failure when trying to access the internet. My TV no longer works either. My power local internet and broadband lights are green, while service is lit up red (3800 hgv-b modem). I did go to my home portal site but couldn't find a run setup wizard button (saw it on a forum post). Not really sure what to do next, any response would be appreciated.
