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.

    Looks different to my RT-AC88U:



    Also there is a new fiirmware: 3.0.0.4.384
    pls check again.

    Hi Everyone,

    I just got a new Play:5 Gen II, got home to set it up with my RT-AC88U router and it won't connect. I tried going to Wireless Setting --> Professional to disable airtime fairness however that setting doesn't seem to be accessible. I am running the latest firmware (3.0.0.4.382_18991). Any help on how to disable airtime fairness? Below is a screen shot of what I see when I go into Wireless settings.

    . Hopefully you can tell in the screenshot that there are no tabs up top to view professional settings as other instructions say to follow to turn off airtime fairness. I do have several other Sonos components hooked and working fine.

    Wish I had found this thread early on. Been trying to troubleshoot for days and found out the exact same setting is causing the issue.

    It’s on their hardware compatability list:

    Me too. Just spent 6 hours factory initialising everything in sight.
    Googled just about everything, but because I was having issues with other devices, I didn’t look for Sonos + Asus. Doh.
    Well done for solving this.

    Damn, you are a savior! Thanks so much, been swearing at those damné speakers for over a year... I bet it'll also help with my Chromecast and my WiFi printer

    Bgluce - did you ever figure out how to get the
    Professional menu to come up? I’ve been wrestling with this for thre whole of today and cannot turn airtime fairness off because i can’t get to the menu. Can anyone tell me the address ? Can I just type it in ?

    I have created a forum account just to testify that I had similar issues with my sonos after upgrading from ac68u to ac88u. After disabling the airtime fairness, problem solved!
