There are people with instability issues, but then there always have been so you can’t use that as pre-emption for whether things will work for you. 

There’s no reason your system should tank by moving to wifi as that is what Sonos is now built for, so provided the app is up to date and you have run the very latest system updates, connecting via wifi should prove seamless. I’m sure there will be a vociferous few that jump in cautioning against it, but ultimately it’s up to you. The volume of those having issues is significantly less then it has been for the last year….

​@MrWhite22, have you tried and changed the SonosNet channel?

Thanks for the info.  All but one of my set up is Play:1, Play:3 speakers so these need to be hard reset before moving to WiFi.  A single Sonos One will move automatically, so this where the playlists etc. will hopefully stay whilst the other speakers are rest.

It’s nothing to do with the channel.  It’s different from the 2.4Ghz channels used by my Wifi and no external interference.  Spotify connect works just fine, so it’s either Sonos networking or SonosNet (or the App!)

​@MrWhite22 

Unless you know for certain that the speakers absolutely do need to be hard reset, I’d just see whether anyone else on here can offer some advice on the best way to change from SonosNet to wifi. I was under the impression that removing the ethernet cable from the speaker that is creating the SonosNet network would mean that each speaker then seeks wifi - but I could be way off. But hard resetting a Sonos speaker is often the source of further problems so maybe someone else can advise on here.

I’ve never heard of a requirement for speakers to be hard reset to move back and forth between SonosNet and WiFi. Where did you read that? I’ve never done that, and my PLAY:1s and PLAY:3s and all other speakers, but newer, moved fairly seamlessly between full WiFi and SonosNet. Was I missing something?

Maybe there's a bit of confusion. Older (non-BLE) speakers need to be reset to change wifi credentials. Maybe not to ad the credentials for the first time?

Not as long as they’re connected at the time the credentials are changed. Requires some forethought if doing while connected via WiFi, or easily done by connecting the speaker temporarily via Ethernet cable. Essentially, the Sonos needs to be able to communicate the change to the computer (WiFi system)  on the device. You should never, to my knowledge, need/have to factory reset the device. 

That does sound logical. A welcome addition to https://support.sonos.com/en-us/article/connect-sonos-to-a-new-router-or-wi-fi-network that does not mention this.

Thanks all for your replies. If you look at the link in my original post, this is where I got the information that you have to hard reset the older devices 

I do see, however I disagree with that persons assertion. As previously stated in this thread, I’ve never had to do such a thing, on any of my Sonos products, including several PLAY:1s and PLAY:3s. Despite switching back and forth between WiFi and SonosNet. 

That's really interesting. So, what's the process you've gone through? Pull out the ethernet first then use the app to switch? I've never had the speakers connected via WiFi before.

Give it a try. If it doesn’t move to WiFi, or give options to move to WiFi, you can always stick the Ethernet cable back in.

The app doesn’t ‘force’ the switch. The cable inserted does, I think. The Sonos software is, I think, designed to take the easiest path back to the router. Think of that as lowest ping time, which is generally wired versus WiFi. 

All you need to do is add your network information in the controller, which then gets transmitted to each device. Then remove the cable from the speakers, and give them a couple of minutes to find/lock on to your WiFi signal. Probably actually a minimal amount of time, but a couple of minutes is safe. 

There is a lot of good information in the wireless and wired systems FAQ. It may help.

​@Airgetlam - just coming back to this.  When you have switched between wired and wireless, is this all done via the app?  I’ve progressed through the process, but the only speaker found it the single Sonos One SL speaker.  None of the Play:1 and Play:3 speakers are found.  Does the Sonos One transmit the details to the other speakers during the set up?

I’m reluctant to progress too far without knowing what will happen!

When you change ‘channels’ for connection, the Sonos software needs to communicate the change to each speaker. If the speakers aren’t already connected, they won’t receive the change until they are connected. So, the easiest/correct way is to wire each speaker temporarily with an Ethernet cable, so it can be ‘seen’, and receive the new information. After that, the Ethernet cable can be removed, if desired.

As long as one Sonos device is connected and seen in the software, you could choose to factory reset the rest, and set them up as if they were new, but that’s a lot of extra unnecessary work. Performing factory resets without direct instructions from a Sonos rep is a bad idea, and usually the last recourse. 

Thanks for the response.  When updating via the app, it finds the Sonos One SL, it doesn’t find the Play:3 connected via ethernet.  Should the app find both speakers or does it do it one by one?

And another question (sorry) - can there be a mix of speakers on WiFi and SonosNet.  For example, if I bought an Era 100, I understand this doesn’t work with SonosNet.  Would I have to have move everything over to WiFi in order for me to add this to the system?

That sure sounds like a potential issue in the electronics of the PLAY:3, but a call to Sonos Support might help.

I have a mixture of Sonos devices on SonosNet and WiFi, they all interact together as one ‘system’. I’ve not found the need to move everything from one to the other.
