Xfinity won’t come install MoCA filter for our apartment

Not sure what to do. Upgraded our speed to 600mbps and none of our devices run smoothly. Several devices that are NOT ours are connected via MoCA, and with all these devices connected in addition to our devices, we get very little functionality out of our internet. Yes, I have paused these devices, but it doesn’t matter—they are still connected and actively using my internet as shown when I log in to 10.0.0.1. One of them is a television…which would take up a LOT of what we’re trying to use. Xfinity rep already visited once and replaced all the wires but added no MoCA filter and blamed our devices for slow speed. I swapped out my modem a week go, changed the network name/password many times, restarted my gateway, and am FED UP.

I read of many people having this issue and after having a MoCA filter installed, the unwanted devices can no longer connect. I asked an Xfinity agent today if I could have someone come out and do this, but she insisted on running diagnostic tests that “take 4 hours to complete” for them to see if they can remove the unwanted devices. I was supposed to receive a text after 4 hours….but big surprise, I did not.

Not sure what I can do at this point since Xfinity won’t listen to me. I pay too much money for this internet, and now I can’t even use it and can do nothing to resolve this issue. And if I have to run one more Xfinity speed test that shows a way faster speed than every other online speed test shows, I am going to scream. Can I install a MoCA filter myself from the inside of my apartment? Xfinity will not allow me to disable MoCA, nor will it let me add a password to it in order to use it.
