XRE-03121 and Bad CableCard

Hello, I need some help.

My DVR (Model XG1v3-P) has been acting up. It keeps giving me error XRE-03121 and upon checking the diagnostics, apparently the CableCard isn't working properly with the message:

"URL: 'CableCARD//ca/ca'

Cable-Card Did Not Respond

Cable-Card may need fixed firmware.

FW Ver: '07.17' / 0x0717"

This also causes my secondary XiD-P box to have the same XRE-03121 error and I know this because unplugging the DVR makes the XiD start working off the internet. If anyone can help this would be great.

If unplugging the box for a minute or so doesn't clear the problem, you'll probably have to swap it out. I don't believe Comcast replaces CableCards in their equipment in the field. See for the locations of Service Centers and Xfinity Stores where you may be able to find a replacement box.

@BruceW​ it's very odd as during early morning/late at night sometimes it will let me through but during the day the CableCard error comes back, some channels don't work, and the XiD stops working.
