Restart your U-verse receiver(s) by holding down the POWER button for ten seconds, then pressing again to restart. (This takes 5-8 minutes and will impact any DVR recordings in progress.)
Restart your Wi-Fi gateway by removing the power cord for two minutes then plugging it back in (will interrupt AT&T service).
Check for snug and secure video cables connecting your TV, gateway, and receiver.
