Sonos Sub 3 stopped working on WiFi

Hi.

For some reason my Sonos Sub 3 has stopped working on WiFi but I have since solved the problem by connecting my Sub directly to my router.

However I am curious as to why this should happen on WiFi but not on an ethernet connection?

I now have my Arc and Sub connected directly to my router with just my 2 One SL's connecting via WiFi as I have had no issues with my 2 surround speakers!

It was only with the Arc and Sub that I had connection issues.

It was strange as when I had the problem the Sub was showing on the Sonos app but no sound was coming out of the Sub whilst it was on WiFi.

Just curious.

By the way I have tried all the usual things like rebooting my router etc.

Just to add that before when I only had the Arc on a wired connection (I think it's called SonosNet), on the Sonos app under 'About My System' I only used to have the Arc on WM:0 but now not only is the Sub on WM:0 but the 2 SL's are as well and they are still on WiFi?

How is that?

I would have thought that my 2 SL's would still be showing as WM:1 meaning connected via a wireless connection?

Thanks for any feedback 👍

The Arc should be wired. The surrounds and Sub should not be wired. All devices should be set to ‘Enable WiFi’, including the wired Arc. All devices should show WM=0 in About My System.

Why should the Sub not be wired?

Even though I have discovered my 'mistake', does it matter that I have 2 wired devices now?

If I only have 2 devices connected via ethernet (arc and Sub), how would all devices be showing as WM:0 if the 2 SL's are connected via WiFi, surely they would show as WM:1 which is what I have on my system?

I am confused now 🤔

Can i just check one thing? On the wired Arc it still has WiFi enabled? You haven't ticked 'Disable WiFi' in the Arc settings?

@John B - I have ticked 'Disable WiFi' but only on the Arc.

I thought it only applied to the Arc, that's why I did it.

EDIT: I have also disabled WiFi on my Sub and now my 2 SL's are showing as WM:1

I don't really understand what's going on but it's all sorted now!

Disabling WIFI on the Arc shuts down the 5 GHz private connection to the Sub. You need to have WiFi turned on for the Arc in order for it to connect to the Sub.

If you still have anything set to ‘Disable Wifi’ you have not got it properly sorted. Please confirm what is currently wired and what has ‘Disable WiFi’ checked.

Doh, that's why as I forgot that the Sub uses 5 Ghz band!

If the Arc was originally set with ‘Disable WiFi’ the only way a wireless Sub could connect would be via the home WiFi. This would give the impression of being online but the Sub audio could routinely falter due to the excessive latency on the roundabout trip from Arc to Sub causing buffer underflow.

As already noted the Sub has to have a wireless direct connection to the Arc’s own 5GHz radio. Or the Sub can be wired if the Arc is wired.

The above would also apply for the surrounds.

No, you’re fine. So long as the Arc’s ‘WiFi’ is enabled the surrounds can talk to it.

Just to say chaps, you really know your technical stuff.

For the record, I have gone back to a wired connection for the Arc only.

I didn't realise for a number of hours that the Sub wasn't working after disabling the 5 GHz band lol

As you can probably guess I am not technically minded and what I like about this forum is no one takes the mickey!
