Looking for assistance with an Xfinity X1 cable box issue. Every 2 or 3 days in the morning when I turn the TV on, my cable box will tell me that “I need to check my connections and reboot” my cable box (Code: RDX 100000) I have an X1 DVR in the L.R. and a mini in the bedroom. Usually I start the TV in the bedroom first and this conditions appears on the screen. I then reboot the living room and everything works. I get the same issue if I start the LR box first.I have talked to tech assistance and they do not seem to have an answer. After resetting my first set of boxes for a couple of weeks, I removed the equipment and installed new boxes in both rooms but the condition still persists.I have seen some info on different blogs addressing this but they seem to be old threads. I am looking to see if anyone has any newer information. I find it hard to believe that the whole Xfinity nation is rebooting there equipment every 3 days. Any help would be greatly appreciated.

I have the exact same setup, but do not have the problem you described. Normally, you don't need to turn off the cable box when you turn off the television. It stays on all the time. If you are turning off the cable box, that could be the problem. If that is not the problem, it sounds like you have an issue with the incoming cable service to your house.

Yes, all works best when the box is left on all the time....sorta counter to the way we have always done it....but it works.

I have the same setup, OP, I also started having problems similar to yours, it was the Comcast entry cable. The techs came out and after an hour determined the signal level was too low and the entrance cable needed to be replaced. In discussion with the techs, we think this was due to a close lighting strike. As noted above the cable box (DVR and tuner) as well as the Xifinity modem should stay on all the time. I will occasionally reboot these just to make sure they are up to date, as I recall these check for updates when they are powering up.
IMHO, complain to Comcast, if you get lucky they will come out and check signal levels.

Sounds like low signal and/or bad connectors at the Dmarc (box on the side of your house). On main TV Hit the XFINITY button, then select the settings icon (at the far right side) then choose COMCAST LABS then SIGNAL STRENGTH and see what you get when you are getting the error. I had a similar issue and they replaced the drop from the main box next door into the Dmarc box outside and all has been fine. YMMV They can also remotely test your signal levels hpwever if it is a bad cable or termination it may be fine when they test.
