Play 1’s do Sonosnet when one of them is cable connected. All speakers connect via the one cable connected speaker. While being connected by cable you used to be able to tell the system your WiFi credentials via the app.

Since the new app for older speakers however a reset is needed, see https://support.sonos.com/en-us/article/connect-sonos-to-a-new-router-or-wi-fi-network The Play 1 is among those speakers,

Before resetting you could try to set your new router to the credentials of the old one, provided you did not erase those from Sonos.

Exact same for me.  All suggestions failed to fix, no help from sonos, and still no solution.  After all these years sonos STILL can't fix a MAJOR FLAW in their own app.

Hi there,

 

I am so fed up with your buggy systems I can't even describe the level of frustration. I am using the latest version of the app on Android as of now and for no apparent reason the app does not recognize the set up system anymore (my wife's phone and app does and works no problem). I tried to reconnect to the system but says it doesn't find any devices on the network (which obviously isn't true - see screenshot)

 

I am sitting next to a Sonos One and following instructions on how to reconnect pressing button on the back - but no doesn't find the system sitting right next to it.

 

I don't want to go through the process of reinstalling the app and setting up the whole system again for the x time - it costs half an hour each time and at the price of your products we should be able to expect that you can employee at least one software engineer and one app developer that can create a better experience than a 10 year old hobby programmer with the attention span of a humming bird could.

 

Rant = off

 

Do you have any solutions to offer that are not requiring me to reset the system completely?

 

Moderator note: We updated this article in October 2023 with new information below.

If you are experiencing this issue and your controller won't connect to you existing Sonos System please have a look at this support article and follow the steps.

If your Sonos app still won’t connect after following the steps in the article, please contact Sonos Customer Care for further help.

 

 

Im having this same issue and none of the suggested fixes in the support article nor anyone at sonos support have been able to fix it.  Now what?  

Hey guys

Im keep getting the same kinda problem every time i open the sonos app it cant see the system even i reset the speakers it wont connect to my wifi in my flat but now i have move and got a new router the same problem cant connect my speakers to wifi BUT

my wife got a iphone 14 i got a 15 but her works i can connect them to wifi and see them in the app on her phone but when i go on my phone it dosent work cant see the system and then when i reset them i cant make them connect wifi on my phone

have tried all those settings you guys have been suggested but it keep not working im pretty frustrated right now Christmas is right around the corner and would love to play some music for the family then they come to see us in the new house hope i cant get some help and spare me with those idiot comments dont need them

Thanks Kind regards Caspar

This worked for me also!

Cheers

This was the issue on my wife’s phone. Even re-installing the app and granting access to the local network in the app did not change the setting in her iPhone. I had to manually grant Sonos access as above and then all issues were resolved.

Oddly enough Sonos has quietly fixed this issue….I basically could t use my speakers for like a whole year. I'm going to send an invoice for the time I've wasted with tech support 

had same issues as OP and shockingly, this part of the instructions worked for my partner’s phone:

1. Close the mobile data connection on your Wife’s iPhone and restart the mobile device by turning it off and turning it back on.
2. Once your wife’s iPhone is turned back on and you are close to one of your Sonos product, turn on the WiFi connection of your wife’s iPhone (keep mobile data off) and connect to the same WiFi name your phone is connected to.

You might look into your router settings, some can seamlessly merge Ethernet, 2.4 and 5 GHz wireless, some can't.

That fixed my issue as well but it did not stay connected when I switched back so I have to leave my phone on my 2.4MHz network for now.

After several weeks, I was finally able to get my system, which consists of several play1’s of varying ages to work with the new app. 
 

Thanks to a post of software engineer Andy Pennell,  I learned that the website play.sonos.com more easily finds speakers than the app. The site successfully found my newest speaker, which makes sense as this speaker probably had more capacity to accomodate the new app. I was then able to perform factory resets on the other speakers and add them to the system. This had to be done with a wired Ethernet connection.  It seems that the Ethernet connection allowed the older speakers in my system to successfully receive necessary updates - a step that was failing before. 
 

After each speaker is added, you’ll need to log out of play.sonos.com and log back in to see each speaker added to the system. When that was done, each speaker would then also become visible in the mobile app. 
 

I’m glad I’ve finally gotten everything working again, but more so hope my experience helps other frustrated users. 

Its so hard not to swear! This suggestion is genius. After years ( seriously) of trying to get our Sonos speakers to work. This did it. Like a previous poster said “when I get the courage to investigate it all again …”. That is exactly our experience, every now and then I think I will have another go Im messing about for hours to no avail. Thank-you, thank-you, thank-you Dinoro. 
WHY is this not listed at the top of the things to try first?

Same issue with arc. I have sworn off Sonos products. Endless frustration that no amount of sound quality can compensate for. 

If anyone else stumbles on this thread, what worked for me is that my phone was connected to my route via WiFi 6 (802.11ax). I turned that off and was able to find my system (and then switched it back and remained connected).

If you are stating that everything else on your network works, I wonder if you might have some VPN or something that messes with your tunneling. 

For example, in my case, I have Private Internet Access (PIA), and even if VPN is not connected, but I have the Split Tunneling enabled within the app, everything else on my mac works great, but Sonos fails on my Mac, though it connects fine on my iPhone. (Even setting up Sonos to Bypass VPN via the Split Tunnel), it still doesn’t work. You actually have to disable that option altogether for things to work. I can consistently reproduce the Sonos app behavior by toggling that setting in the app, all while not affecting anything else on my Mac. 

You may or may not have that same app on your computer, but this is a direction you should look into, to isolate the problem. If your Mac is indeed on the same network as your speakers, it is unlikely that you will have a failed connection, unless something is standing in the way. 

Hope this helps guide you in the right direction.

I think that this is the best plan for you.

For some reason your network is not able to support SONOS. It’s clear from your screen capture above that your router is not sending data to any SONOS units shown except the ONE near the bottom and the indicated throughput is much lower than expected.

Well as an update 2 speakers have dropped off my system. As expected. Yay!

I'm going to sell these speakers and try and get some money back for them. 

Same issue

After about 20 hours of painstaking troubleshooting I eventually removed my entire Sonos system from my home and factory reset all devices. I then installed it all with an ethernet cable direct onto my main router and added the devices to the WiFi I wanted to use them all on. After about the 6th attempt of removing the entire system and adding it again I eventually got my sonos system to talk to the Sonos app on my Android phone. So it's all working, for now. Let's see how long it lasts. Fingers crossed. 

My feedback to Sonos remains the same, as nothing that expensive should be that difficult to install and use. Not in this simple plug and play era.

I know it's just a matter of time before it just all of a sudden stops working again. Sigh.....

I've got a bunch of expensive paperweights too . Unreal!  

I’m not taking it personal at all.  But good luck with the new app that will never solve your problems.  

I have already gone through all the network things you have mentioned. This seems to be the fix for sum but not all. Again I appreciate your feedback. You are taking this way too personal for someone who doesn’t work for Sonos. Hope you have a Great Day! Stay Safe. I will wait and see what Sonos does next. 

As I said earlier in this discussion: Once you’ve decided that the problem must be e...] or cannot be e...], you are likely to be blindsided.

Play the percentages. There is no point chasing the 0.01% possibilities before ruling out the 90% probability.

So that would be a “No” to the query as to whether you want help with your network instead of blaming? 

Here’s the facts (whether you consider them a “lecture” or not, I don’t really care).  A few years back, there were a couple incidents of actual bugs in a single Sonos device connected with a certain few TVs.  The main thread for that problem reached hundreds of pages in a few days.  There were also dozens of peripheral threads dealing with the same problem.  Soon after, Sonos acknowledged the bug and stated they were working on it.  They eventually released a fix.  

Contrast this with the half dozen of so posts like yours that seem to show up after an update.  An update which always entails a reboot of each Sonos device.  These reboots often uncover problems with a router’s IP table, because a reboot causes the devices to all request a new IP.  If your router IP table is in a wonky state caused by a power outage or something similar, it can hand out IP addresses that are still in use by another device, wreaking havoc with the cross communication required by a system like Sonos.  That’s just one of the problems.  A VPN running in the background can cause the problems you are seeing, as can poorly configured mesh nodes or extenders.  However, if you aren’t willing to accept it may be your network, there’s no way to begin to fix it.

Now I’ve already wasted too much time on someone who clearly has deaf ears to this subject, but I will ask one last time - Do you want help fixing your network or not?  If not, I’ll go help someone who does want help.

Thanks for your input. Sound kind of sensitive to my comments. I in no way am accusing you of anything. I am frustrated along with several others over the Sonos App. Not you.  For someone who isn’t working for Sonos, you sure sounded like it. Maybe bring it down a couple notches.  People don’t need to be lectured about their point of view. This is a forum for issues with Sonos.

Hope you have a Great Day.
