Watching U-verse TV

I had problems with our att modem (WiFi, U-Verse, home phone). Installed the new att 5286AC modem that att sent me. WiFi works fine, but can’t get U-Verse to work. After 15 seconds, get “Lost Signal” error message. I can go to another channel and it will play for 15 seconds, then same error message?

One of our TVs just says ATT Uverse unavailable. I can press Restart Receiver, and eventually just gets back to same error. Pressing Menu key does nothing (kind of like calling, emailing, or whatever to try to get help).

According to the user manual there is a Library tab to click on that will show a downward pointing arrow next to downloadable shows and movies. There is no Library tab at the top of my U-verse screen on my iphone.  How do I find downloadable movies?

I updated the Uverse app on my iphone and now can not login. I get an error saying 'the certificate for this server in invalid.  You might be connecting to a server that is pretending to be udvr.asp.att.net .." There is an answer to this back in 2016 saying to reinstall the app and reset th

I have the Bally sports Wisconsin package. I used to be able to stream live games on my iPad or laptop. Now I can stream on my TV or stream on my phone, but Bally does not allow me to stream on any devices. This is a recent change. Bally has said it is an ATT Uverse issue and wants me to confirm tha

Seems likethis has been a reoccurring problem over the years. I am seeing this error when trying to log in on all my devices. I have changed my passowrd and done al the suggested fixes and still no luck. I can log into my ATT account.
