Configuring the Orbi RBR850 kit with an AT&T Fiber BGW320-500 Gateway -fequent DNS errors
Hello, I am using an Orbi RBR850 with the AT&T Fiber BGW320-500 Gateway and followed to the letter AT&T instructions as well as some found in this forum to configure the RBR850 in IP Pathrough mode....
Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy. 📡
What FW version is loaded on the Orbi system?
Is IPv6 enabled on the RBR?
Try setting custom DNS to use Cloudfare or Quad9 instead of Automatic.
Try the RBR in AP mode connected to the ATT modem router with IP-pass-thru disabled as see if DNS errors continue.
The firmware version is 7.2.6.31 on the RBR850.
IPv6 is Disabled on my RBR850. Should I turn it on?
IPv6 is available on my BGW320-500 and seems to be enabled.
I am trying to avoid using the RBR850 in AP mode as I was told I would lose some functionality if I did so.
Also as I mentioned before, I am puzzled by the following fact:
My RBR 850 has a MAC address at the bottom of the router, ending with 74. When I go to my BGW320-500 and click on "Device List" I see xx:xx:xx:xx:xx:75 where xx are the same digits as my RBR850 MAC address.
Still in the BGW320-500 configuration under Firewall>IP Passthrough
Passthrough Fixed MAC Address > Device list gave me the MC address ending with 75, but I manually entered the one with 74 at the end. Could that cause issues?
Should I use Dynamic DNS Service on the RBR850 (it is currently unchecked).
Try the 75 as seen by the ISP modem first.
So, I changed the RBR850's MAC address on the BGW320-500 to match the one on its Device List (the one that ends with 75). We will see how things go from here and report back after 24-48 hours of use.
It would be interesting to know from this community if I should do the following:
- Turn IPv6 on in the RBR850?
- Make any other change in my RBR850 and/or the BGW320-500
After changing the MAC address in the BGW320-500 to the one it sees, instead of the one listed at the bottom of the RBR850, I ran a diagnostics test on the BGW320-500. Everything Passed with flying colours, the 2nd time I ran the test. The first time I ran it, I did get a fail on the Reverse lookup secondary DNS though, while everything else was fine.
Try the different MAC address first.
What Firmware version is loaded on the system currently?
