So I got my new Roamio 4Tuner and have it hooked into my network via MoCA connection (MoCA bridge hooked into my router in the office and another MoCA bridge hooked into my Roamio 4Tuner in the MasterBR). The MoCA bridge in the MasterBR is hooked into my Roamio through the coax and the ethernet port ... not sure if the ethernet port is necessary, but it doesn't connect to the internet otherwise. Anyway, I'm now trying to hook up my first Tivo Mini via MoCA and I'm having the same issues. I can't find the Roamio or connect to the network. When I run an ethernet cable from my router into the Guest Room that I'm hooking the Mini up in, I'm able to get connection to the network, but it can't find the Roamio. Roamio and Mini are both on my account, sharing is enabled and MoCA doesn't have a password enabled. I've tried rebooting, etc. to no avail. Haven't called Tivo tech support yet as I haven't had the time for a lengthily call. Any ideas for me to try? PS: I've tried hooking the Mini up in different rooms in the house as well, but I get the same results.
