Dropped WiFi calls on iPhone X iOS 12 ATT with Orbi RBR50
I’m experiencing dropped WiFi calls with my iPhone X. The calls will typically last only a few seconds before the call fails. I had been using the WiFi calling on my Orbi RBR50 and 1 satellite for ...
Removing the Orbi from DMZ FIXED the issue.
What I don't understand is why it is now suddenly an issue, must be iOS12 then.

Great that removing the DMZ solved the Wifi calling issue. I went through the manual of your ISP router. Two things that might caused DMZPlus configuration not to completely work:
1. The DHCP addresses assigned to the DMZ port should be marked as public addresses. Please check if that is done.
2. There should be a reserved IP address for Orbi in the ISP router with no firewalls enabled
I placed the Orbi back into DMZ (having it outside the DMZ definetly not desired as you indicated would happen I ended up with double NAT and then some applications I tried to use would no longer work).
I followed your instructions. For the first step the router would not let me modify the field for public/private IP addresses the drop down box only offered private. However, when I validated the data from step 2 of your instructions it looks like when I placed the Orbi into the DMZ zone the router automatically assigned the Orbi the public IP address for the ISP router (mapping it) and is shows firewall disabled. I included a screenshot of this config setting from the router. Based on what I see I believe the router is configured to achieve the desired configuration you were wanting me to setup.
I did try another call again and as expected the call failed.
Thanks for all your assistance in troubleshooting this issue.
You might contact the Mfr of the modem and ask them about this and see if they might have any information in regards to DMZ and placing routers into the DMZ and let them know the differences your seeing with the iPhone and wifi calls.

I just saw your last post after I did previous reply. I'll reach out to Pacer and see what they say!

Ok, let us know if they respond with anything.
You might try AP mode with the Orbi as suggested and use the ISP Modem as your main host router. Then you don't need to use the DMZ on the modem.

Hello. The manufacturer is PACE for the 5268AC. The latest firmware for that device is badly broken for DMZ+. I'm not sure if that's the root cause but the workaround offered by ATT was to actually disable DMZ+ until updated firmware is released. You can search ATT forum and you can't miss the thread. Verrrry long. The workaround is marked as the solution.

Modem FW may have broke good speeds between the modem and Orbi in router mode:

Here is the lurid history around the 5258AC and DMZ+.
The bottom line here is unless the user is able to follow the instructions to manually downgrade the firmware on the Pace unit, the RBK50 will never see the full benefit of a gigabit connection. ATT will not push a downlevel version of the firmware and they will not mail a different gateway. The only proven solution to get a different gateway is to have a technician deliver it.
Yes, and it would be recommended to get into a different gateway OR something thats just a modem ONLY that doesn't have any router or wifi built in.

This gets a bit into a gray area. ATT doesn't work like a DOCSIS 3.1 modem, meaning you can't just got to BestBuy and get a modem for a VDSL2 copper or Fiber connection. The standard policy is to use one of 3 available gateways. The newest available gateway is an Arris BGW210-700 and is the better performer. This is the one I have. WiFi is disabled and I use the Ethernet ports to serve IPTV traffic to Uverse TV service, and of course one port in IP Passthrough for the Orbi.
If you look around in DSLReports there is method some people use to connect their own routers directly to the ONT bypassing the gateway altogether.
Of course, some ISPs, mostly DSL, don't offer more than what they support or BYOM. So for those ISP, users can be limited. Thus using Orbi will be a bit more problematic, so DMZ and AP mode are options for users to try in these cases.

Add IP Passthrough to your vocabulary. People with Arris devices won't understand DMZ or DMZ+.
Seems a shame and wasteful to use such a high powered and expensive device to be relegated to merely functioning as an access point.
Cheers
Good luck.
