We recently had the X1 Xfinity platform installed in our home and have been having issues with it over the course of the week.
Seemingly at random, the router's connection to the internet would drop, but we would still be able to access the router and change settings through the default gateway, so nothing has been wrong with our ability to connect to the router.
We tried calling tech support for assistance and followed their instructions, which mostly consisted of simply unplugging the coax cable and the power supply for different intervals. That didn't help, however, so we tried connecting the router to the wall directly instead of the splitter that also connects to the cable box.
This also did not help, so we thought that the router was to blame and that it was defective. We had it replaced, but then experienced the same problems with the new router.
This leads me to believe that the cable itself, in the walls or outside, is the problem.
If this isn't the case or if someone has had some experience with this kind of situation, I would appreciate some help.
