Does anyone have a comprehensive-ish tutorial on how to circumvent this/just have your own router without having to deal with AT&T. My dad has AT&T fiber and I've been wanting to fix this for him but haven't gotten around to doing the research. IIRC there was some reason why it was a good idea not to use the built in bridge mode + second router and the "better" (ugh) solution was to allow the AT&T thing to do the security handshake and then reroute all the traffic by placing an OpenWRT box between the AT&T router and the fiber box. Would love it if someone could point me in the right direction so I don't have to sift through google.
When AT&T was using an ONT + Gateway there were ways to circumvent traffic going through their Gateway while still allowing the Gateway to talk to the ONT and unlock it. But they've transitioned to deploying a single box (BGW320s) that are a single unit.
You can still put the Gateway into passthrough mode and disable it's features.
He's got the two box solution, so I guess my memory served me correctly about the workaround and I'll try to check the discord in the sibling comment for more help, thanks!
