U Verse TV Signal Problems

The television locks up and a message will come on saying we've lost the signal. This occurs up to a dozen times an hour at certain times. This happens when only the television is onm no other devices. This also happens the same time every day, 

This has been hapening for nearly two years.

How many TV's do you have with AT&T U-verse set tops?  Just one or more than one?  If more than one, do they all do it or just one?

 

How is the set top that is having issues connected to your U-verse Gateway, via Coax, Ethernet or Wirelessly?

 

When this happens, does your Internet have issues as well, or just the TV?

 

When this happens, what lights are on/blinking on the front of your U-verse Gateway?

There are three Tvs, only two on at any one time. This condition occurs regardless of which set or if all sets are on, One set is connected by HDMI and two are wireless. The internet slows down and has lost connection during these events. The U-Verse Gateway's lights all start wildly blinking with some blinking faster. This happens if all devices are turned off with just one Tv on and it doesn;t matter if the Tv is HDMI or wireless.

Okay, so what you're experiencing is a condition where the U-verse Gateway and the AT&T Network equipment it talks to have lost communication in full or in part in fact, the Gateway is probably doing a resync.

 

At this point it looks like you're probably going to need an AT&T technician to come fix a problem with your service line.  But we can firm that up a bit, if you'd like.  Visit http://192.168.1.254/ , click on the Broadband tab and look for a table with statistics like sync rates, Attenuation, SNR and error counts.  Take a screenshot of that table and paste it in a reply for us to review for you.

 

BTW, an HDMI cable would connect your TV to the DVR or Receiver and cannot connect the Receiver to the Gateway.  The choices for how the DVR is connected would include Coax and Ethernet.

I have not been able to access  http//192...... A half dpzen attempts yield the message asking if I want to kill it or wait. After waiting through 3 cycles I then choose the other. Thanks for the clarification regarding the HDMI cable. What I should have mentioned is the situation also occurs when watching recorded programs from the DVR. Still a sync condition? And with all three Tvs? When I asked them before I either got no answer or was told to check cables and reboot. That got old after the fist time. Thank you JefferMC for your time, trouble, and expertise..

When watching recorded content, the content is streamed from your DVR to the STB at the TV where you are watching.  A disconnect when that happens would indicate that there is an issue in your internal network.  This could be in addition to a service line problem, or all your problem could be your internal network.

 

So, I ask again, how are your Receivers and DVR connected to the Gateway?  The choices are normally:

1) Coax,

2) Ethernet,

3) Wi-Fi (not a choice for the DVR) using a dedicated WAP

 

I do not understand why that link doesn't work, unless you:

(1) have changed your Gateway's IP (as I have mine; that link doesn't actually work for me at all), or

(2) have an additional router between the Gateway and the system running the browser, and are using the same subnet on both sides of the router (which is discouraged, because it leads to issues like this).

 

The link should work from any PC connected to your Gateway.

 

If using Ethernet to connect your various devices, please describe how they are connected, including any switches (including models), or other network equipment involved (routers, powerline adapters, bridges, etc.) and their models.
