Xfinity XB6 gateway - changing settings while offline

I have been running an Xfinity gateway (a device that is a modem and router in one) in bridge mode. (Bridge mode makes the gateway act as a modem only.) Now I want to switch it back to act as a Gateway. I have been trying to connect to the device through a wired connection while it stays offline. The reason for this is that the alternative would mean connecting to the internet without a router.

This plan is not working.

Xfinity calls the device
XB6
On the device is says XB6-A.
The Xfinity web page indicates that the IP address is http://10.0.0.1
I have tried that address.
I changed Firefox about:config to network.stricttransportsecurity.preloadlist false
in case the browser is redirecting to https

Xfinity has specified a model number of TG3482G as possibly what this is. Maybe Arris Touchstone TG3482G?

I logged into my Xfinity account to see if I can change gateway settings there but no dice.

I can do a factory reset on the gateway. Is that the next logical step? I just fear that that will force me down the road of connecting to it while it's online.
 
XB6? Those are old. If it gives you any shit just have Comcast swap it out for a newer model.

I have mine in bridge mode currently. As far as I am aware you have to connect with an Ethernet cable directly to it to log into the admin page.

Interestingly, I got the gateway 'login screen' while still connected through my personal router (which is in turn connected to the gateway). Previously, I thought I had to be plugged in directly to the Xfinity gateway.
Now it's saying that I have the wrong password. I tried winging it to reset the Gateway but guess I got the reset device steps wrong. I need to look those up.
 
Ok, it's working.
In the web based gateway settings it does say Arris TG3482G. So, I was right in that regard.
