@user_vt8jt7 Good morning! Thank you for taking the time to reach out to our Community Forums Team and bringing your security concerns to our attention. I can see how having devices connect to your network would be alarming. I'd be happy to take a look, and get you in the right direction for getting this resolved. We may need to have a technician come out and install a filter. To begin, can you please send a Direct Message with your name, and service address?
Click "Sign In" if necessary Click the "Direct Messaging" icon at the top of the page (looks like a text bubble) Click the "New message" (pencil and paper) icon Type "Xfinity Support" in the "To:" line and select "Xfinity Support" from the drop-down list which appears. The "Xfinity Support" graphic replaces the "To:" line Type your message in the text area near the bottom of the window Press Enter to send it
Perhaps your neighbors are inadvertently connecting to your network / gateway device via the MoCA feature that's built into the gateway device. MoCA (Multimedia Over Coax Alliance) is an alternate hardwired way to connect devices to a home network if ethernet cabling can not be used/run. It uses the existing coax cable wiring instead of ethernet cabling.
If the MoCA feature is enabled, and 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 street drop to keep the MoCA 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. First, unplug the coax cable line from the jack on the gateway device. Then 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 you are not using the MoCA feature on your home network, you can put the POE filter right at the back of your gateway device instead.
