My U-verse signal was lost twice today. First time, it came back on, second time, no. I followed the instructions. When I reboot from the receiver, the TV picture comes back on for about 10 seconds then goes back to lost signal, so I contacted ATT tech and they set up an appointment. I can't do anything with the gateway because it's located behind the TV and unfortunately I'm disable, so I can't handle that. This is really strange because I've lost signal before and this has never happened, it always comes back on by it's self. Any ideas?
