Asus RT-AX82U - Sonos issues solved.

Hi everyone,

 

Got a Asus RT-AX82U router and after upgrading firmware to Version 3.0.0.4.386.45934, my Sonos stopped working and there was no chance to re-connect the Sonos and or the speakers.

the only solution is to downgrade the firmware back to Version 3.0.0.4.386.45898.

The system re-connected and my Sonos works excellent again.

Please check Asus website and download downgrade/router rescue app from Asus to be able to downgrade.

Goodluck.

    One thing I noticed is that after factory resetting the SONOS speakers they still remember a few settings, such as system pairing. These settings still persisted even after I reset the SONOS app and then logged back in to my account. Conclusion: The SONOS factory reset process cannot be trusted, at least not together with their app.


    Exactly how are you completing a factory reset on your speakers? Just unplugging then plugging back in?

    If so then follow these instructions instead to Reset your Sonos product

    Not once have I experienced a factory reset speaker remembering previous settings.

     

    I performed the factory reset exactly as in the link you supplied, @Mr. T  Unplugged power cable, replugged it while keeping the speaker’s connect button pressed etc. And the speakers and Sonos app responded correctly to the factory reset too.

    I didn’t notice that some settings were kept at first either. But later, when I was connecting one of the speakers with ethernet cable directly to the wifi router (right after factory resetting that speaker), the Sonos app told me that the speaker belonged to a system of two and had to be uncoupled before proceeding. There is no way that coupling could have happened by itself, because the other speaker was entirely powered down (and unplugged), and the Sonos app had been reset (but then logged back into my account). So either Sonos is saving some settings in my account data or in the speaker — even across factory resets.

    Previously I had downgraded my firmware as couldn’t get my RT-AX82U to see my speakers at all. However, due to other non Sonos related issues I needed to upgrade to the latest firmware version.

    I updated to 3.0.0.4.386_46061 last night and at first couldn’t see my speakers but after a bit of tinkering all is working as intended.

    My setup is just two speakers both connecting directly to the router via wi-fi

    Steps I took:

    1. Updated firmware through router UI
    2. Reset router through UI - Administration/Restore tab - Factory reset with Initialize ticked
    3. Uninstalled Sonos controller from PC and Sonos app from phone
    4. Reset speakers as per the official guide
    5. Reinstalled app on phone
    6. Setup new system on a single speaker via mobile app
    7. Reinstalled controller on PC
    8. Added additional speakers through app

    I tried numerous ways off getting connected to my existing system after step 2 but nothing I tried worked.
