New Asus RT-AX82U/AX5400 Router Sonos System Not Showing Any Recommendations?

All the suggestions didnt work for me using the latest Asus firmware 386.2_6 .

What did work, as soon as I set the setting, was to change the Wireless Mode in 2.4Ghz to “Legacy”

Chiming in here as I bought my RT-AX82U yesterday and immediately had connectivity issues with my Sonos system (Beam, 2xPlay:1 and Sonos One) on latest firmware. Rolled back to the 3.0.0.4.384.9948 after finding this thread and looking good now so far.

So is the firmware rollback the general ‘fix’ so far or is factory resetting (and assuming restoring settings from backup) the way to go with keeping up to date? There does seem to be a number of security vulnerabilities patched between Nov 20 and May 21 so I’d really prefer not to be set adrift firmware wise.

Thanks.

Asus recommend updating to the latest version, and then performing a factory reset. This should let you stay up to date with security patches as well as avoiding any connection issues documented here 

Thanks James. I did this today - updated to latest version and then forced a factory reset (twice actually!). Afterwards my Sonos system was reachable briefly and then speakers started dropping out from the Sonos app - particularly the Play:1s.  Also noticing a 10-12 second delay when starting a song from Spotify.

Rolled back to 3.0.0.4.384.9948 (even without a factory reset after) and everything is fine.

I spent a couple hours with some birthday Ikea Symfonisks and an Asus XT mesh getting nowhere. Airtime fairness is disabled by default so that wasn’t an option. I wasn’t keen on doing a factory reset as the rest of the family was obviously awake and not keen to have the network down for an hour while I rebuilt the mesh.

In the end I found the best bet was to make one of the bookshelf speakers plug in via ethernet to a satellite Asus XT8 unit and become the master. It then sets up it’s own Sonos wifi network. After that all the other speakers join that special wifi network (and then connect to the internet via the master speakers ethernet). The downside is that all your speakers have to be within range of that speaker’s wifi to do the join. Good enough for a single room setup - I have Ikea 2 bookshelfs and a Ika lamp from the Symonfisk range hooked up - they can be airplayed from the main wifi network eg reachable from Apple TV, iphones etc.

I’ll try the factory reset maybe another time.

No joy with upgrades+factory reset. On the latest firmware my Sonos system is all over the place.  As soon as I roll back everything is fine.

Is this even going to be looked at by Sonos and/or Asus?

It is clear that ASUS don’t care at all (and it is 100% their problem to fix). Get a different router, I personally recommend AmpliFi.

Just to add regarding sugestions of turning off QoS and Wifi fairness.

Wifi fairness was disabled for both 2.4Ghz and 5Ghz by default.

I initially logged into my RT-AX82U (latest firmware: 3.0.0.4.386_43588) using the (iOS) mobile app. When I searched for Qos it showed a setting and I marked both bands as disabled. Still couldn’t use / register my Sonos Play 1’s.

I’ve since logged into the router from my PC and when you go to router.asus.com there is an menu items for Adaptive QoS as below. This was still turned on. I have now turned it off as below & have successfully added my first speaker back to a new system (having reset the iOS Sonos app). Worth checking both settings or, ultimately, don’t trust the Asus mobile app! 

 

In update to my comments a few months ago, Firmware Version:3.0.0.4.386_43129 is working fine for me on my RT-AX82U even with QoS enabled and without having to split the 2.4 & 5 Gh networks

I see that there is a new firmware version 3.0.0.4.386.43588 available.  Has anybody had any joy with this one or are we still stuck in November 2020?
