Just got my new Roamio Pro set up last night on MoCA, it downloaded the fall service update, and I got BHN to pair the Cisco CableCARD (PKM803 with 1.5.3_F.p.0601 - we'll see how that goes). Everything is working great. I noticed, however, when checking my router, that the Roamio's ethernet MAC appears as "connected" to the router even though currently it's set as MoCA only and there is no ethernet cable plugged into the jack. I can "ping" the ethernet address. If I try to access it via a browser, I get prompted for the login, but then get a "resource not found" error (if I connect via browser to the MoCA address I can access the web-based Now Playing). Is this just a function/side effect of the internal MoCa+Ethernet bridge?
