U-verse TV Equipment

How do I add another uverse receiover to my accouny and where do I get one ISB7500 or equivalent

I need the remote code for my Insignia Fire TV F20 series. I've looked everywhere and tried all codes I could find. I couldn't find a specific one for a fire TV.

My wireless uverse receiver has bricked out on me . I need to get a replacement unit sent out to me, but I've had no luck with the phone numbers I have for customer service . Is there a number I can call and speak to someone directly instead of going through all the computer assisted crap . I'm old,

He added the box to my account and it still show unprovisioned. I ebonite’s my WIRELESS ACCESS POINT and rebooted the set top box and reconnected it to the network. The problem is still the same.

One of my wireless receivers doesn't work. I have restarted it many times but it still doesn't work. All I keep getting is a big red X on my TV screen. I need to replace it . How can I do this. Is there a customer service number I can call to get this done?

I’ve had ATT for 15 years because it’s the only service for my area and every night at 11pm the signal is lost. I called many times for help and they just walk me through the steps I already tried. I’ve called so may times and get told that my TV must be on a timer, or the walls of my house are mess

Received error message the set top box does not match the account settings

Some nice fence people cut our ATT fiber cable so we were without for 24 hours. Now our wireless receivers will not re-connect after following the re-connect onscreen instructions. Any suggestions?

After ATT Tech installed the new "Internet Protocol Set Top Box, I keep getting the message "set top box does not match account settings". The serial number of the box is 171945303. 

I moved 2 months ago, but carried over my equipment and services with AT&T. I brought all of the equipment from my old house to the new house.  The service tech had to change out my TV receiver and took my old one.  I am now being billed $150.00 for missing receiver that I don't have
