Surround Sound Setup Errors.

14 replies
1055 views

I have an Arc+Two Sonos SLs. My router is an ASUS RT-AC88U. I continue to receive errors connecting the devices in a surround sound setup.All firmware is up to date on router and Sonos devices. App is up to date.

My connection quality is strong on all devices (40dbm) and I have played around with different frequencies and channels to reduce interference. Internet speeds are fine. I live in an apartment and aside from the 15 devices I have connected I have 10 available WiFi networks in range. So despite my efforts on picking an channel that is not congested, it still probably is.

I ordered a boost but don’t feel like I should need it. Any suggestions?

Note that when running Sonos in WiFi mode on RT series routers you should disable Airtime Fairness.

Do you have a wired device at the moment? Can you play through the surround speakers if you use them as standalone speakers rather than surrounds? What Sonos devices do you have?

I do not have a wired device but had to wire them to setup the first one. I can play music through all speakers independently and as a group (have not tried stereo setup). Arc, Two Sonos SL right now. sub comes tomorrow.

So will the surrounds not add at all? What error do you get when you try?

Experimentally (this is not for a permanent arrangement) if you connect the surrounds by ethernet to your router will they add as surrounds?

The surrounds wont add at all. It fails on the first step setting up the left speaker. “Surround Setup Error - There was a problem adding the surround speaker”

I can try the wired thing tomorrow. Will see if support comes back with anything as well.

I am wondering if there is a fault on the 5GHz radio on the Arc, which is the way the surrounds would normally connect. That theory would seem more likely to be true if the surrounds add when wired.

If you haven’t done so already, i would submit a system diagnostic and contact Support with the confirmation number.

Turning off Airtime Fairness on my RT router fixed my issue.

Further, it had a very dramatic impact on the experience of using Sonos. The app detects devices immediately compared to tens of seconds. Devices now almost immediately connect to the router when reset. The experience is fantastic now!

I reverted all previous changes (manual channel switched back to auto, firewall turned back on, switched back to 20/40 frequency, etc). Still works great!

Thank you for your help ratty, and for your initial help John B.

I’m having a similar problem - I finally got it set up but the right speaker wouldn’t participate in the true play tuning , and is not playing in the set up.

I have similar problem with the ARC and two Sonos One SL. I recently purchased a new house equipped with two Ruckus APs, Ruckus Switch and my own NetGear Modem and Edge 4 Router. I keep getting the “Surround Setup Error” message even after resetting the devices to factory settings or setting up in different orders. I somehow couldn’t find airtime fairness on my APs or Router config. My Sonos sub will arrive soon but I’m losing my excitement for the setup because of this nightmare.

How were you able to set it up successfully?
