ASUS Router firmware update 2020/11/26

Sadly, I had to downgrade my ASUS router from the latest right now, back to 3.0.0.4.384_9918.

I have an older Sonos One with hardware version 1.21.1.8-2.1 and it could not work. It could connect to the router, but it would not appear within the Sonos System :(

Am frustrated because it looks like a lot of vulnerabilities were fixed in the last few versions.

I’m on firmware 3.0.0.4.386_45375 on my RT-AX88U ASUS router and all my sonos kit has been stable since my last post :)

Thanks. I’m using RT-AX58U. Do you have older Sonos hardware speakers or are they the latest hardware versions? Before I reverted my firmware, I followed your recommended settings as well.

I’m running an Arc, a Sub 3 & 2 x IKEA sonos book speakers at the rear. They are all at the latest firmware from Sonos. Everything needed a reboot after changing the settings, but it’s all been good since 

I thought it may help to show my settings. My Sonos is on the 2.4ghz network

Make sure you reboot the router last! That is important 

Sounds awesome. Looks like they have the latest hardware, or at least Gen2. My Gen2 speakers can work fine with the latest router. But my Gen1 Sonos One can’t. Maybe time for a trade-in/upgrade:)

I’m having the same issue with an ASUS RT-AX58U router. I made the changes that Colin suggested above and still have issues. I’ve also been on the phone with Sonos and ASUS. Ready to throw this router in the bush. 

Checking back to this thread over a year since I started it and am amazed over how many that have had the same issue, some people seem to have resolved it and some not.

Anyhow, I decided to give it a new try with latest firmware, installed it and hoping for the best. But it didn’t took long before the the disappointment, the Sonos deviced immediately dropped out from the network.

I tried the different tricks with Airtime, IGMP and roaming settings mentioned in this thread. but all without success. 

Don’t know why, but this time I decided to do a factory reset on the Asus router instead of the Sonos speakers and wow that resolved the issue!!  The Sonos speakers are back and still working, it also seems to have resolved an issue with my XBOX where I previously couldn’t get download speeds over 20Mbps, now I have 200+. 

I couldn’t see any settings to be different from before. 

I tried the factory reset this morning and it worked! I had done everything else including a reboot but it took the factory reset for the setting changes to take effect!
