Before I ask my question, here's some background: We live in an aprtment and have two Premiere XL4s, one in the living room and one in the bedroom. The living room XL4 is connected directly to the router. This one is also serving as a moca bridge to the one in the bedroom. I can stream between the two just fine. The Tx/Rx rates hover around 142 Mbps/112 Mbps. The way the cable is configured in my apartment is as follows: Point of Entry ==> Splitter 1 Splitter 1 connects to cable modem and Splitter 2 Splitter 2 connects to both Tivos. I read on tivo.com that a moca network in an apartment wouldn't work because a POE filter couldn't be installed where the cable comes in, but it obviously works in my situation without it. Just to be doubly sure that my neighbors can't access my network, I set an encryption key in the moca settings. So, my question is whether or not installing a POE filter where the cable comes into my apartment is a good idea or am I just trying to fix something that isn't broken? Thanks in advance!
