ASUS RT-AC88U

I recently bought a new wifi router/access point an ASUS RT-AC88U

Once I switched over to it I found that I had sporadic access to my Sonos speakers (Play 3, Playbar + Sub).
Sometimes I could connect to the speakers, sometimes I couldn't. When I could connect I'd sometimes be able to see all the rooms and other times only 1.

I played with a bunch of wifi settings and finally tracked down the culprit.
Wireless menu >> Professional Tab >> Airtime Fairness
This setting is enabled by default. When I disabled it my access to my Sonos was restored to it's former fully functioning glory.

Thanks! Just like everyone else, this is a savior of a post. Just about threw my new Beam and Sub out the window.

Outside of this fix, is everyone liking this router? I’ve heard mixed security reliability for Asus?

Update to my reply of last night.
The issue came back today, I open spotify app and tru to connect to my play 1 but It never does.
I open the sonos controller, it may conect for about 3 seconds and then drop.
I have clear the way of any interference, I have re boot both, app and play 1.

Is the anything related to DCHP or DDNS ?

Thanks

Send in a diagnostic and get one of the 24x7 Sonos support sites (on the contact page) to look at it.

If you rebooted it isn't likely to be DHCP although you might want to assign static/reserved IP addresses to avoid future issues.

DDNS isn't going to impact Sonos that I'm aware of. Regular DNS can be an issue if you use a blocker to filter out sites. Whitelist the Sonos ones to deal with that the easy way.

This is driving me crazy.

I have a Beam connected via ethernet and a couple of Play1 and a Sub using an RT-AC86U router, everything worked fine.

Since I had connection issues at my place I bought another router and as a mesh node also enabled the smart wifi option.

Things stopped working, I saw the sub was not connected anymore to my system.

The next is the timeline of the events:

  • I removed and add the sub again but no luck.
  • I started searching and disabled the “airtime fairness” option since that was a known issue.
  • Done, it start working again.
  • Sub stopped worked for no reason, nothing changed.
  • I removed it an try to get it back again, this time is not working. I got stuck when I have to press the button, the app is not detecting the device.
  • I tried to reset it, the app detects the device but gets stuck in the “Connecting” screen.
  • I notice the both Play1 works fine out of the box, I have to do nothing.
  • I read somewhere that the DHCP might have something to do, that might be an internal IP issue (:neutral_face:). So I attached the devices to their own IP, it won’t hurt.
  • I tried to connect the sub to the router via ethernet, AFAIK Sonos will use the “less cost” path so via cable device should be able to join the Sonos system.
  • Nope.
  • Restart the BEAM
  • Nope
  • Restart the BEAM and reset the Sub
  • Nope
  • I created a “guest network” on the router for 2.4ghz, removed the ethernet cable from the Beam and sub.
  • Nope
  • Tried the above like 3 times
  • I started to write this post while trying last one (actually last thing I did it was creating a “guest network for 5ghz”) and it worked :confounded:

What bugs me like hell is that the Play1 worked fine all the time, it’s just the Sub the one that refuses to work. I’m afraid this won’t last too long and Sub will get disconected again. I refuse to think Sub has hardware problems, I saw many router/network problems and this was working since I added a mesh client to the home network.

Anyone has any idea or suggestion how can I get this to work?

Thank you - this also worked for me with the newer (essentially the same but WiFi 6 compatible) ASUS RT-AX88U

This worked like a charm…..after 8 hours of hairpulling….changing this setting fixed everything. Thank you so much for posting!
