Resolved: U-Verse Broadband Disconnecting Every Few Minutes
I have had AT&T U-Verse at home for almost two years and the service has worked exceptionally. A few weeks ago, my modem started randomly disconnecting from the broadband network every few minutes. Nothing had changed in my configuration ever since it was first setup. It was baffling and frustrating because it also impacted the IPTV connection.
First, we called AT&T and they performed some line checks. They identified issues with the external wiring and dispatched a team to fix. This improved the HDTV service tremendously.
However, this didn’t resolve the broadband disconnects. I tried reconnecting every one of my computers and wireless devices but that didn’t help. I rebooted the modem and reset the wireless settings and the firewall settings to factory defaults – didn’t help. My modem was already sitting above ground and away from any blocking or interfering sources.
Finally, in desperation, I was ready to reset the modem to factory defaults and start from scratch. That’s when I noticed the RJ-11 cord and the power adapter were touching. I figured that maybe the power adapter was interfering with the RJ-11 data line. I moved apart the two cords so that they were not touching and rebooted the modem without resetting to defaults.
No more disconnects!
Thanks for this! I’m hoping that’s the case with our issue, too. We’ve had Uverse for almost a year now and it would occasionally crap out about once a week. I’ve had a Uverse tech over my house four times in the past three days. He replaced our coax line-in with CAT5 and replaced our router. It would be fixed for a while, then naturally after he’d leave it would continue to disconnect every few minutes and then auto repair about 30 seconds later. After reading your post, I traced the wire from the router, through the basement ceiling to the house connect and noticed a few spots where the CAT5 wire was within enough proximity to an electrical cord that it set off the alarm on my voltage detector. I either stapled those close electrical wires further away, or re-routed certain sections of the CAT5 wire and will trace it. If this fixes it, I owe you a beer.
