Xfinity gateway has voltage on coax barrel to nearest outlet ground
The Comcast bond was fried where the service enters the home. I had some grounding issues with my home electrical that have since been fixed. So I get that it backfed voltage back to that and fried it. But all electrical issues have been corrected.
I have had 2 Comcast service calls, PG&E, apartment maintenance, and a certified electrician to my home in the last week.
Comcast service techs said there is voltage on the coaxial cable coming from the modem even when it's not connected to anything..
The electrician also checked my home for a bad neutral, bad ground and other issues and there is none. PG&E confirmed there is no problem with our service.
All outlets we plugged the modem into on different circuits was back feeding voltage onto the coax line. I have had 3 different Xfinity gateways here and all had the same backfeed. At this point, I'm convinced that it is these new gateways that are allowing the fact there is no ground on their power supply to backfeed voltage back onto the coax
If anyone has any insight for this, please let me know.
