Advertisements I just picked up my new Comcast XB3 modem on Friday and set it up, really nice to have 180 MBpS download speeds and it has MOCA built in as an option. So I turned on the MOCA option in the modem and pulled the ethernet cable out of the Roamio I have in the living room. Once I setup the MOCA on the Roamio and rebooted it, all seems to work (I have an internet connection and was able to connect to Netflix and Amazon Video). But I've noticed that sometimes when I browse a show on the Roamio, it loses internet connectivity briefly and then it returns. And when I tried a video on Amazon, same thing, it lost connection a few times and paused. Any ideas where to start troubleshooting this, not sure how many users here have an XB3, if that's relevant.
