Thank you for posting this. I have had this same issue. It's very frustrating because I had my own brand new Arris 3.1 modem with new velop 6600 system and do not want to broadcast Xfinity. Not because I hate Xfinity but because I live in a culdesac (with a culdesac behind it) and there are already too many channels being used for wifi. It's horrible. I tried this same setup with bridge mode. I could not get the internet out of the XB6. But i believe i was only trying to right port it shows as the port to use in the manual. I didn't even think to try the left. I wonder if it would work. I called Xfinity and the girl had no clue what i was telling her, how i wanted to use my own router and that it had its own DHCP server built-in so i wanted to only use bridge mode on the XB6 for unlimited data. She told me it wasn't possible and that Velop is not a compatible router. She had me recycle power a few times, and never mentioned the other port. So for now i am bridging my velop, but my speeds dropped going this route. Im on 600Mbs and i get 200Mbs wirelessly now. When i was using my Arris Modem with Velop router i had 500-700mbs wirelessly. If i connect direct or hard wired to the XB6 over my switches i get 700mbs. So you think the left jack might be the answer?
