Network connectivity issues. Tons of unknown MoCA devices on network.

I moved into an apartment about 4 days ago. As soon as I set up my xfinity modem/router (the rented one) about 15 devices connected. When I check my gateway (10.0.0.1) I now see about 29 total devices connected, 7 are mine via WiFi, 22 are via MoCA. I only do WiFi or Ethernet connections.

From my understanding, this is my neighbor and I's networks "speaking" to each other through our coaxial cables. I did learn that I apparently have a neighbor named Payton with a couple tvs, a macbook, and a several gaming consoles. How do I fix it?
