Logging in to the gateway router to find my neighbor’s information.

This has never happened before, and I’m pretty angry because as per usual, we can’t get in touch with someone who works in the United States, who’s has been properly trained on technical issues regarding WiFi. This is why people hate Comcast. But I digress. 

Lately I have been having issues with my internet, and it says all of these random people are connecting to my wifi. I’ve had to pause them all because I don’t know what’s happening. I changed my passwords, changed my wifi names, etc. I logged into my router, 10.0.0.1, and it kept saying my password was incorrect, I finally fixed that and logged in. It brought up my neighbor’s information. Not mine. I was so frustrated I drove down to Comcast to ask them [Edited: "Language"]. I know they can’t diagnose while I am away from my router, but they did assign a tech to me, so I may have an answer in the next day or so? The guy at Comcast says “You may be sharing a coaxial cable??” This has never happened. How could we be sharing a cable wire? 

Please help!!! 😫

Xfinity modems use MoCA.  It's Ethernet over coax.  Your neighbors could be intentionally or unintentionally connecting to your gateway.  There is no security in the MoCA version Xfinity unleashed on the public.  You can turn it off with the app, but many report it turns itself back on.  They're also running up your data usage, and using bandwidth, plus it's a security problem (and a legal one depending on what your neighbors are doing).   It's especially common in apartment/townhouse situations. 

Try an MoCA PoE filter (point of entry filter).  It blocks the higher frequency MoCA uses.  If you have no MoCA devices yourself, like a coax connected cable tv box, you can screw it right to the back of your gateway.  If you do have coax connected devices, it should go on the coax where your service enters your residence. 

They're around $10 on Amazon, or you can order one and have it delivered to a Walmart in a day usually.  You can also get one at an Xfinity store if there is one by you.  Search for "MoCA PoE filter" to find one. 

Alternately, you can use 3rd party equipment without the "feature".  https://www.xfinity.com/support/articles/list-of-approved-cable-modems 

If there really is "bleed over" with WiFi itself, then it's an undisclosed security exploit that remains unreported to CISA.  Your solution would be to stop using the hardware immediately and NOT use their equipment until it's disclosed and resolved.

@flatlander3​ I spoke to my neighbors, lol, they have no clue, they just reported that they’ve been having issues with their internet. I have a cable box in my room, but the modem/router is in the living room. Should I install it in my apartment? Or down by the point-of-entry into the residence? Which would be best? I cannot turn the moca off, it’s annoying to me. I’ve been planning on getting the filter, but I originally didn’t realize it was my neighbors until I did a little more digging. Thank you for the suggestion.

@user_c60dfa​  So, if you are using one of their coax connected cable TV boxes, it won't work anymore -- or 'perhaps' it will just connect to the neighbors if you screw the MoCA filter into the back of your gateway.  It may not work very well if it is connected to your neighbors gateway depending on distances, and you'd be burning their data if you are not using the cable lineup (a different app on it). 

If it is one of their WiFi connected boxes, and it connects that way (not the coax), then you can screw the MoCA filter to the back of the gateway.

If you can track down the splitter that connects your jacks together in your apartment, it could go there on the input of the splitter.  Point-of-entry into the residence works too if you can't get to that.  You are just trying to block out the signal your neighbors are broadcasting.

@flatlander3​ I had the tech come out. He couldn’t figure out where the splitter might be located in the wall where our lines are. It could be anywhere. But she has a Moca filter on hers now, so it’s much better!
