Unusual high data usage and unidentified devices connected to your network?

What you need is a MoCA filter between your coax cable and your router/gateway!!!!!!! 
This MoCA problem exists especially in multi-home buildings where all subscribers are hooked on to the same connection. Xfinity gateways are MoCA enabled this sends a signal into the coax lines letting ALL devices talk to each other. So your neighbor unknowingly taps into your data! 

I had this problem where my usual 200gb usage suddenly spiked to over 1gb and I had devices connected to my network which were not mine. When I logged into my gateway’s admin, I suddenly was in someone else’s router and I could see all their settings. 

After some research on the internet, I came across the MoCA issue with Xfinity and I aquired an MoCA filter, installed it, reset my gateway and it immediately solved all my issues!!!!

Xfinity should know about this issue and give each subscriber a filter with their modem. Denying this issue and just telling subscribers to change their passwords or sign up for faster service is not the solution!!!!!
