Now you might be wondering why is my ATT Uverse box not working.

How to Fix the ATT Uverse box not working?

There might be many reasons for your ATT Uverse box not to work correctly. Here, let’s first identify the common possible issues in your Uverse box impacting the functionality and how we can solve them.

  1. Cables

One of the common reasons your ATT Uverse box might seem like it’s not working might be due to any problems in the cables. Always check the cables for any physical damage and internal damage. You can use a multimeter to check the continuity. 

There also might be chances where the cables are loose, connecting the wires in the right spot tightly and securely.

  1. Power

One of the main things required to run a TV is power, so check for the power source. When the receiver is turned on, the power button will have a green light in front of it. Try unplugging and plugging the receiver into a working power outlet. Also, you can also notice a red light from your Uverse box.

  1. Wireless Access Point(WAP)

To troubleshoot the WAP, unplug it from the power outlet for 20-30 seconds and plug it in again. After WAP is turned on, pair the WAP and the receiver again. Press the WPS button on your WAP and the Ok button on your receiver. After about two minutes, the link light on the receiver will turn green.

Even when the receiver is too far from the WAP, your AT&T Uverse box might not work.

  1. Hardware Issues

Generally, if there is any problem with the box, the ATT Uverse box will have a blue light to notify the user. Check for any burnt fuse or check the antennas in your receiver. If nothing of the troubleshooting works, you can also take the receiver to an expert technician, or if you still have the warranty, AT&T can replace it. 

You can also check the battery by pressing your remote. Press the AT&T button on your remote, and you will see a bright red light if the batteries are good. But if you see a dim red light or no light, change the batteries.

  1. Internet

AT&T Uverse box needs an active and stable internet connection to function correctly. In case of a weak strength, you can reboot the router. Moving the router closer to the receiver ensures it receives good internal signal strength.
