I am getting an XRE-03121 error for one channel (CNBC)... and after several months, I discovered I could test my signal strength using the tool on the X1 research lab page. When I did check the strength, I found that it is very low (one bar). What do I need to do to improve my signal strength? I've contacted support about the error code several months ago - restarted the system, did a system refresh, etc... all to no avail. Any ideas?
do you have more than one set top box? have you tried pressing the "A" button and running the system refresh?

Rustyben - I do have more than one set top box (but in different rooms)... and I have done the system refresh a few times without any improvement. Not sure what to do next?
may want to call 800-Comcast and select TV. ask the agent to run the internal troubleshooting guide (einstein) and let it test your line.

Yes I am using this. Could it be a signal strength issue? Would improving the modem do anything or getting an WiFi extender get rid of the error?
would you try a power unplug of the wrieless set top box (30 seconds) then plug back in. working?

I’ve tried all the suggestions here in this forum and still can’t access my HBO channels. Nothing has changed with my account and it still says I’m subscribed to HBO which I pay for each month so it wasn’t a promotional thing. I do NOT have a wireless box as others in this forum had issues with when getting this error code. When calling Comcast, no one seems familiar with this code either. Is there a Comcast tech reading this willing and able to help besides redirecting back to this forum? I will gladly PM if someone has the time to look into this for me. Thank you in advance.
call 800-Comcast, select billing, ask agent to perform a deep background account refresh. that can take up to an hour to complete. working now?

Got my X1 system today, have done a full 10-minute system refresh twice, 6 hours later and pretty much every channel is not working.
call 800-Comcast and select billing. ask the agent to refresh your entitlements and to perform a deep background account refresh (can take up to an hour to complete). if they don't know what that means ask for a supervisor.

I am now also having this issue, channels not working on any tvs, but working online or on the phone. There is no way I can see to send you a message as you suggest, clicking on your name only tells me you're online and shows me all your posts and kudos and such. The technical support agents are not able to resolve this issue.
hi, since you have now made your first public post you can now see the message menu. be sure to sign in at the upper right corner of the web page first.
