XR500 QoS error: device not found

[David84]

Hello. I updated my xr500 router with firmware V2.3.2.144, I reset it and after setting everything in Qos a popup comes out with this "error: device not found". I tried to install other firmware, new version of Netduma 3, factory reset done 5 times but it didn't count to anything. You can help me? currently i have installed version V2.3.2.120 but it doesn't work with any version (installed firmware and done factory reset every time)

I have a pppoe fiber connection from Italy

Downgrade to a previous firmware, do a factory reset from the interface, then re-upgrade again please and it should be working

I had already tried but it doesn't work.

luckily I just solved it like this:

factory reset
firmware installation .114
factory reset
I turned on all devices (including ps5)
router setup wizard.

now it works correctly.

Maybe it gave an error because the ps5 console was not turned on at the time of reset?

Yes that's possible, glad to hear you got it sorted, thanks for posting the solution!
