Advertisements I just switched in my area from WOW Cable to Charter. Everything is working great and all the TiVos and Minis are talking to each other. But the installer said that they don't need POE filters for MoCA setups anymore and removed that from the connection. I'm curious if anyone else has run into this and if that's correct. I have a firewall enabled on my router and everything connects to that before hitting the cable modem, so I don't think there's anything to see anyway, but I'm just wondering if there's a way to tell if signal is leaking out to neighbors or whatever.
