RAX120 Router Random Disconnects

Hey everyone, I know that I'm not the only one with problems on the Nighthawk WiFi 6 devices, but thought I'd post my most recent headache. My hardware consists of a Motorola MB8600 DOCS 3.1 modem w/...

Same issue on and off for me, too.

To be clear, the problem is that DNS Relay is failing, right? I can manually assign ISP DNS to clients and all is well (or, as mentioned, configure an alternate DHCP Server/DNS Relay Server).

 

My experience...:

- First noticed it with 1.0.1.114.

- Applied 1.0.1.118 hotfix and neither better nor worse.

- Rolled back to 1.0.1.108 and all was well.

- Applied public release of 1.0.1.118 and no issues for days, perhaps weeks.

- Configured and applied an Upstream QOS policy and rebooted. Now, this evening, I've lost DNS resolution via RAX120 DHCP twice.

- Currently: I removed the QOS and it ran fine for a few hours, no issues and just now re-applied the QOS.

 

So far so good. We'll see. If it craps out again I have my config backup and FW 1.0.1.108 ready to go if need be. Fingers-crossed :)

 

Thanks!

I wasn't very clear... Within an hour of enabling QOS, the issue re-appeared, and then again shortly after.

 

Thanks!
