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 https://www.xfinity.com/support/service-center-locations for the locations of Service Centers and Xfinity Stores where you may be able to find a replacement box.
