I am needing to set Arris BGW210 gateway into bridge mode in order to utilize Google Wifi router. I can not seem to find straightforward exact step by step instructions I can follow. Any advice would be greatly appreciated.

It might be easier to set the WiFi router to bridge mode & let the Arris handle DNS routing.

I think that's how I set mine up... It's been a long time since I've had to mess with it...

I think I did the cascaded router option that's farther down that post. I remember having to restart things.

Thanks for the AT&T forum link and comments.

For those with a high level of technical knowledge on the subject, is the cascaded router option the preferred method?

This has turned out to be more difficult than I first imagined. I feel like I'm about to break something. I wish AT&T would offer an option to forgo the gateway router and opt for a modem only.

IP passthrough is what you want - this will assign the public IP to the Google Wifi router and pass all the traffic to it. I do this with my Orbi. Don't forget to turn off the WiFi on the AT&T router.

I may have ended up with the cascaded router option to get my plex server to work outside the network. Also they had just released a firmware upgrade that broke stuff...

However I set it up its been working for a long time now.
