Optimizing performance when used with AT&T Arris BGW210-7000
I have an Orbi 6 router. The model is actually RBR850 (not RBR50). Firmware version is V3.2.18.1_1.4.14. I have connected it to my AT&T Fiber 1gbps service via Ethernet port into the Arris BGW210-7000 router. My config looks like the following:
- Turned off both 2.4 and 5G radios on Arris
- Set Arris in IP-Passthrough mode with DHCP-fixed option to assign the WAN IP address to the MAC address of Orbi router.
- I do not have TV or Phone service from AT&T. Only Internet.
- I do not have any hardwired connections to the Arris router. Arris router connects to the ONT on its Internet WAN port and to the Orbi on the LAN port.
- I want Arris to do the least amount of work (I think that is ideal) and make Orbi do most of the work.
I want to make sure that I don't have two DHCP servers being used or double NAT. My Orbi shows the following settings. I also include a traceroute log. Does this look correct? I am surprised that Orbi has a domain name server of 192.168.48.1 which is the IP address of my Arris router. I do have a public IP address for the Orbi (172.125.78.52) so that looks good but I am not sure about domain name server that is show as 192.168.48.1 on Orbi admin page. Is that optimal? Or do we want something in the public internet cloud space?
What am I missing here? 192.168.48.1 is the address of my Arris. Is that correct? Do I have double DHCP? Is that even possible? Should I disable some packet filtering on Arris for better performance?

Re: Optimizing performance when used with AT&T Arris BGW210-7000
Netgear has set up a community forum specifically for the Orbi AX product. Most of the people who watch that forum are more likely to have experience with Orbi AX and know how to work it better than those of us who follow this "general Orbi" forum. Might be more likely to find someone who has a solution if the question is posted there:

Thank you.

Any progress on this?
Even though Orbi is in the IP Pass thru section of your ISP modem/router, it should be getting most of it's traffic thru the IP pass thru feature and not being routed by the modems router portion. You are in a double NAT condition, however IP Pass Thru will work in this condition when connected to a router or gateway modem with a built in router infront of the RBR.

Re: Optimizing performance when used with AT&T Arris BGW210-7000
I gave up. There is far too many parameters and I don't see what else I can do or try. I setup the AT&T Arris gateway in IP passthru mode. Internet works on my wireless devices connected to the Orbi 6.
I get high bandwidth of 300-500 mbps but sometimes my kids will say that scrolling on some apps is slow on their phones. I have no idea why. I figured maybe the DNS is an issue because on my windows laptop I often get dns_probe_finished_nxdomain problem for 1-2 seconds and the page loads automatically. But who knows what is going on.
I have no more inputs/parameters to make further progress or debug/triage the problem.

Re: Optimizing performance when used with AT&T Arris BGW210-7000
What happens if you remove the IP pass thru on the modem and configure the RBR for AP mode?

Be sure that Traffic Meter is disable on the RBR.

I haven't tried that yet and will try that this weekend.

Re: Optimizing performance when used with AT&T Arris BGW210-7000
Those Arris gateway modems can be problematic when it comes to external routers being connected.
30 feet or more is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected.

I had to do a factory reset on my Orbi Pro SXR80 and SRR60, all works now.
I have ATT&T and it is in line with my BR500 and then I run the SXR80 and SRR60. I did not use IP-Passthrough mode with DHCP-fixed and It's working fine for me now. Just keep it inline when doing the reset on the Orbi and setting it back up.
It was driving me nuts for 3 days.
I did this in the video below and it did not work for me.
