user_pi7a9  Great question. Here are some steps to help: 

1. Run a System Refresh

On your main X1 remote, say:
“System Refresh”
Or go to:
Settings > Help > System Refresh

2. Power Cycle All Boxes

Unplug all X1 boxes (main and secondary)
Wait 1–2 minutes
Plug in the main box first and let it fully boot
Then plug in the secondary boxes

3. Inspect Coaxial Connections

Check all coax cables for tightness and damage

Still Not Working?

Use the Xfinity Assistant or app to run a diagnostic
Let us know. We are here for you!
