I had the cable guy at my house because the new cable modem Cablevision sent me only worked for a couple hours and then just stopped working. I also had a Moca POE filter handy which was ordered from tivo.com. The cable guy was more than happy to install it for me and said he would test it out first too with his equipment. He thought it was just a voltage filter even though I mentioned I wanted it to setup a moca network. Anyways he said well the filter is working in that it is blocking out everything. He installed it outside just before the cable from the pole hit a 3-way splitter into the house. At the end I found out he did not know what a moca network was. I don't need a moca network yet as I only have 1 tivo in the house so far, but it would've been nice to have had the POE filter set up for when I finally get a mini or another tivo for the 2nd tv (no Ethernet connection in the bedroom). Was the placement of the filter wrong? I have no clue where the 3 lines from the splitter end up in the house. It looks like 1 goes up into the attic and the other 2 towards bottom of house, but don't see those 2 lines come in. I have no basement. Bummed that I couldn't get the Moca POE installed. I'm hesitant to touch anything as I finally have everything connected with the new cable modem & smart router. I do want to go moca in the near future. Will the signal really bleed out without the filter? The cable guy said since things went digital he would think it would be hard for it to go outside of my home. But then again he didn't know what a moca network was.
