What is WAN ‘registration’ in Arris G36 parlance when establishing a DOCSIS connection?
Using xFinity’s app, I had partial success activating a new G36 at a new service address. In looking at the WAN status, I have QAM both up and down, and the various categories of activation all say ‘Complete’ except the final ‘Registration’ item which has displayed a couple different statuses depending on when I look. The xFinity app’s progress always hangs and times out at ‘checking connections”.
Further, I wonder if this relates to me closing all the WAN side ports before I ever plugged the thing into xFinity. Clearly xFinity won’t get no satisfaction if they are trying to ping the router from outside, but its fuzzy how that would result in the router itself never achieving ‘registration’. TBH, I don’t even know what some of those other ports that default to open are used for, but I wanted to do what I could to prevent xFinity from forcing a firmware update that I cannot live with and cannot reverse. This G36 is very new and already running DOCSIS 3.1, but I don’t have the specific version at-hand as I craft this.
In poking around elsewhere in the forums, it might be relevant that I think I have IPv6 disabled on the WAN side, but I’m not in a position right now to enable it and retry the activation.
What does Arris G36 WAN ‘registration’ mean, and how might xFinity activation fail to provide what the router wants? Any thoughts would be appreciated.
