One of my most popular technology posts has consistently been one I wrote about our ATT DSL modem back in the day before Uverse. We’ve been on that for a few years now, and I suspect many people have switched over, too, because traffic to that post has gone way down. It had a good life.
Fortunately, I haven’t had as many problems with Uverse as we had with the old modem yet. But lately we have had a few times where it dropped our connection suddenly. The fix has been to restart the gateway.
Usually when this happens, all my lights are green, though sometimes one might be flashing. I may have to record which one if it happens again. I begin getting errors on all my services that the certificate has expired (but what it means, I suspect, is that it can’t connect to email, etc.).
I have bookmarked the Uverse gateway’s status page in my browser, and since wifi is still operational, I can go there. That should be http://192.168.1.254, but check your gateway documentation if that doesn’t work for you. It may have a different default address. From here, I can confirm that the connection is down, and I can restart my services (Connection to ATT, WiFi, Phone). You can try restarting individual services, though that hasn’t worked well for me. What has worked to restore service is to click on “Restart Your System” and reboot the whole gateway.
This has happened to us twice in a week, so I hope it doesn’t mean the Gateway is going out. When we first switched over, ATT came out a couple of times and replaced our gateway. The service tech said they weren’t very good and they had a lot of problems, but once we got a decent one, it’s lasted a couple of years. Maybe it will be time for us to upgrade our service to fiber and maybe get a new gateway.
Here’s hoping it doesn’t come to that, or at least that I don’t have more hassles to vent about. But if I do, I’ll be sure to write about them here!

Just spent over an hour with AT&T support because our U-Verse services (TV, PHONE & Internet) suddenly went down. I’ve learned that 1st I reboot the Gateway – if that doesn’t work 2nd I reboot the Fiber Box and then reboot the Gateway again. Today neither of these worked. I had the Broadband light solid green but the service light was off. With the technician I reset the gateway a third time, reset the Fiber Box for the second time and then the gateway for the fourth time. They had me disconnect the red fiber connection into the gateway and then reboot it for the fifth time. The service line did not come on. The technician had me reboot the gateway for the sixth time and finally the broadband right AND the service light both came on – our services were back! They did a line test and found no issues with the line or the service but are sending a technician out who after running all of their tests will tell us the gateway is bad and replace it. We also went through the switch from DSL to UVerse and the awful gateways that they first used. Unfortunately I still think they are using very cheap gateways OR it is a convenient excuse then they are having service issues!
