Seeing 30+ devices connected to my gateway via MoCa
I recently moved into an apartment and set up my Xfinity gateway. Shortly after I realized unauthorized devices began to access my gateway. I paused those devices but more kept popping up. I used the admin tool realize that these devices were connected via MoCa. I was even able to see these devices IP addresses and also was able to access a neighbors SSID via the admin tool. If I can access neighbors SSID and also see neighbors devices on my gateway, my neighbors can also see my devices on their gateway. My own devices have been paused on my own Wi-Fi because of this. Leaving me with terrible connectivity.
Not only is this a massive issue trying to work from home and secure a consistent connection it also poses a massive security risk. I’ve contacted Xfinity support multiple times for them to ask me to change my password and restart the modem. Which is not the fix. A MoCa filter needs to be installed to stop myself and my neighbors from seeing each other’s IP addresses and device info.

MoCA implemented by Xfinity is a massive security problem. A POE (Point of Entry) filter is around $5 on Amazon. You can screw that right to the back of your gateway. That configuration won't work if you have a cable TV set top box. It would have to go directly before the splitter that feeds the TV and the Gateway. This might not be all that practical for an apartment or multi-dwelling situation with a rats nest of cable.
What's the real solution? Ditch the Xfinity gateway. Then you don't have the problem.

If you don't have cable TV box, right on the back of the gateway works. MoCA is high frequency. The POE filter is a low pass filter that blocks signal either into, or out of your gateway.
You can try to turn the feature off, but your Xfinity gateway will turn it right back on if there's an MoCA device somewhere on the line, and that signal can travel quite some distance to your neighbors house. Even down the street.
