U-Verse signal intermittent in the evenings, bad gateway or bad connection? - DirecTV

#1
For the last few days, our U-Verse signal will intermittently cut out for a few seconds to a few minutes at a time. It's worse in the evenings, cutting in and out in 5-10 minute cycles and showing the "U-Verse signal has been lost" screen on both TVs. As this is happening, sometimes the broadband light on the gateway will turn red for a moment and then it will reacquire the signal. I've tried restarting all the AT&T devices, including a "full house reboot," unplugging everything and then turning them back on, starting with the gateway. After rebooting many times for days in a row without solving the problem, I'm convinced that either the gateway has gone bad or there is some sort of interference on the line. Is there anything else I can do or should I schedule a service appointment?
