A local shop just upgraded to uVerse a few days ago. After initial setup, wireless network worked fine with default SSID and password. Then within 24 hours, wireless devices could not connect. Changing the password allowed devices to connect for a few hours then back to no connection.
Devices are claiming authentication failure.

I'm having this exact same problem ATT has sent a technician out twice the first guy changed out the modem thinking this fixed the problem left because it works initially after the modem gets rebooted but drops after 10-15 minutes. Second guy said they get little training regarding actual WIFI issues and said it could be detection issues with metal roofs,fluorescent lights and aluminum beams however you can set any devices near the modem and they drop as well. Also the indicator light doesn't blink consistantly and stays solid a lot of the time. Anyways just got att a couple months ago and still no WIFI. Wired line works without fail from the modem ports. Still would like to get wireless.
