Orbi Wifi 6 AP vs Router mode performance
Hello, I have an Orbi AX on the ARRIS BGW210-700 gateway for my AT&T 1GB connection. I could use the Orbi in AP mode with my Arris gateway as router or I could use the Orbi in router mode and my ...

Thanks for your input. My topology is very similar. I moved my configuration to Arris in Passthrough and Orbi in Router mode this morning. I was surprized to see tha the Orbi is using 10.0.0.* as IP set for my local network instead of the usual 192.168.1.*. This makes me be afraid to have a double NAT and that somehow my Arris was not really in Passthrough mode. However, on the Advanced Home tab of the Orbi UI, I can see a "real" WAN address as IP address in the Internet Port section, so it looks like the AT&T IP WAN address had been correctly passed to my Orbi WAN interface. Do you experience the same?
I also thought that it might be because I kept 192.168.1.254 as IP address for the Arris and that somehow could created a conflict to be on the same subnet so the Orbi had to use a 10.0.0.* subnet. So I moved the Arris IP to 192.168.100.1 et a DHCP set of 192.168.1.254 but that didn't change anythins and the Orbi still default his IP range for local network on the 10.0.0.*.

After you changed and applied the 192.168.100.1 address to the modem, did you go back and manually change the RBR850 to 192.168.1.1 IP address, set the pool size, from and to, save and apply the change and reboot the RBR?

Yes, I did and it works fine as far as I can see. I was just a bit concerned that I did something wrong when seeing the Orbi going by default to the 10.0.0.* net mask.

Thats automatic and by design when the setup wizard detects the up stream modem or router is using the same 192.168.1.1 IP address string. Orbi avoids this by changing to 10.something. Once you changed the modem to something different, then Orbi can use .1.1. again.
