Frequent disconnects / restarts since switching to XB8 modem

I am having this exact same issue. Extremely frustrating. A tech is coming by for a second time.

Extremely disappointed in this service. I NEVER had this issue when I brought my own modem/router combo equipment, EVER. The moment that I switch to Xfinity's equipment, suddenly their infrastructure is a problem. Honestly, how can that be? I have had this issue since day 1 with the XB7 when I started the new service, and subsequently also the XB8 shortly thereafter which was provided by the technician during the site visit.

I do not want to hear how this is a me issue or related to gaming. Why can't this be fixed? ALL services cease, both wired and wireless, when the modem resets. All of them. Again, Xfinity's equipment appears to be the x-factor in all this. The technician was very nice though, that is the positive in all of this. What the tech did was replace the coaxial cable from wall-to-modem, replaced a segment of the internal in-wall coaxial cable as well as cleaning some channels in the outdoor building access box. Sadly, none of this seems to have resolved the repeated disconnects.

@XfinityLinda​ The technician did not swap the cable and there isn't a splitter being used in the connection. The problem seems to have ceased for the time being (52 hours without a disconnection at the time of writing) but I'm continuing to monitor it.

@XfinityMarcos​ I'm not entirely certain but I believe the XB8 was restarting. When checking on the device during connection issues I think it was going through the power on cycle (flashing orange light, flashing green light, then solid white).

All devices were losing connection and my PC which is connected through ethernet would also lose connection so I don't believe the issue is related to the wi-fi channels.

@Osasanajimi have you noticed if the reboots are happening around the same time or different times? 

@XfinityRoberto​ At first the reboots were happening daily at around the same time late at night (2:30 am - 3:30 am) so I assumed it was maintenance or updates being pushed out but then it started happening throughout the day and the frequency increased.
