Done and thx.

Likely cause is set-top box not properly connected to gateway.  Check physical connections.   

All connections are good. Thx. That is not the issue.

I would physically connect that new settop box to the gateway via Ethernet cable and boot it up.  I’ll be highly surprised if Att shipped you a defective box.  

Here’s some additional reading material you can look at.
