Constant Connection Issues

Here are some suggestions when using Cisco switches.

While I don't recommend using WiFi ("Boost" Mode) for a system this large, your post above has confused me because part of it indicates you intend to use WiFi, but you have wired PLAYBAR to the Cisco Switch. If you intend to use WiFi, remove PLAYBAR's Ethernet connection. If you want to use SonosNet, make sure that WiFi credentials have been removed from the SONOS system. If WiFi credentials are present and one or more of the SONOS units is struggling with its wireless connection, portions of the system can flap back and forth between WiFi and SonosNet. This does not work well.

What is the source of your music? NAS? Computer? Online service? Phone/Pad?

Is this issue new? Has the system ever worked?

Hi Buzz, thanks for your reply. The system has been in for around 6 months, I had issues like this initially and I did loads of things (Too many to remember what actually improved it) to try to resolve, and the issue was less frequent but still there now and again, it was only yesterday when the constant drop started (I didn't make any changes to the network to indicate root cause). When I refer to Wi-Fi i mean that those speakers are not connected via ethernet, only the bar is. My music source is Macbook and iPhone using mainly the Radio by Tunein and Spotify through the Sonos App.I have set wifi up using credentials via the app. Should I set the system up from scratch again, and if so what is the best practice for setting up please? I will check out the Cisco info and post an update if I make any changes.

Thanks again, Rik.

As buzz intimates, leaving WiFi credentials stored in the system when in SonosNet mode can lead to instability. Go to About My Sonos System and check that all devices show WM:0. Then go to Advanced Settings/Wireless Setup and remove ('Reset') the WiFi settings.

Your system is indeed in 'Mixed Mode', which as noted can lead to instability. Scroll down on the Wireless Setup screen and you should find the 'Reset' button. If you can't see it you may be using a larger iOS font.

The Mac controller no longer supports system setup tasks.

I have a suspicion that the Wireless Setup screen may not be showing 'Reset' because the system is part using SonosNet and part using WiFi. You need to get all the devices showing WM:0.

Try power-cycling the units which are WM:1. (The WM:2 ones are just home theatre satellites connected to a WM:1 main speaker so ignore them for now.) If you can wire the WM:1 units temporarily so much the better. If none of this works we may have to adopt more forceful tactics.

Ok, did power cycle on the 5 devices but all still indicate WM: 1 I'm afraid. I am unable to connect these devices via ethernet 😞 The OTP for the player is blank so it may not be connected via ethernet after all (I can't get the bloody thing off the wall!)

'OTP' in About My Sonos System? Ignore it, it has no relevance.

Okay, we need to dislodge the WM:1 units from the WiFi. A factory reset on those units might do so. However a subtler approach would be to temporarily change the SSID (or key) on your Orbi setup. You'll obviously need to tweak the phone too for the time being in order to re-connect with the Sonos. In the absence of an accessible WiFi the WM:1 units should seek out a SonosNet connection.
