Hello user_1pdm2m, thank you for joining us in our Xfinity Community forum. Unknown devices can be disturbing. I know I would be if I suddenly found devices I was not familiar with. Have o tried viewing the connected devices through the Xfinity app? Being able to "hunt them down" can be difficult at best. The most secure move would be to use the app, and remove those devices. You can also change your Wi-Fi password (that can be aggravating, but keeping unauthorized devices or users out of your network should make it worth the hassle). We are here, and happy to assist you.
First. Is this a Comcast-rented gateway device ? If so, check to see if the MoCA feature in it is enabled. If it is, and if you do not have a PoE (Point of Entry) MoCA filter installed on the coax line, yours and your neighbor's gateway devices will be able to connect with each other like one big network. Disable it if you aren't using it. If you are, install a PoE MoCA filter on the input port of the first splitter off of the drop line coming directly from the street / pole to keep the signal in your premises and to keep the neighbor's signals out. Your neighbors should also have PoE filters installed.
To disable MoCA on your device go to the gateway login http://10.0.0.1
Default login info is: Username: admin (all lowercase) Password: password
Once in you will find the drop-down on the left of the screen that is labeled “Connections”.
Click the drop down---> click MoCA---> right side of screen click “disable”---> save changes.

Bear in mind that we've seen many posts here that the MoCA feature gets turned back on with their overnight re-boots / updates for the device. The best policy is to be sure to use that PoE filter ! Amazon has them: https://www.amazon.com/SNLP-1GCW-Filter-Eliminate-Multi-Room-Interference/dp/B07SLD9QPH
Or you may be able to get one for free at your local Comcast / Xfinity store. Or book a tech to come out and install one for you.
If the MoCA feature is not being used on your home network, you can place the PoE filter at the back of your gateway instead.
