Sonos speakers not showing on iPhone

23 replies

Hi, I have five Sonos speakers in the house, 2 in the lounge, 2 in the kitchen and one portable one. At any given time some or all of them disappear from the Sonos App and cannot be found from an iPhone connected to the same WiFi network.

Right now I am typing this on my iPhone and I can see all the speakers in the Sonos app. My wife sat next to me, connected to the same WiFi, and she can see none of them. Sometimes it’s the other way around. Sometimes we can see a couple of the speakers and not the others.

Any ideas?

Hi

This has been resolved with help from the Sonos support team, but it was not a Sonos issue in the end. They realised that my iPhone was getting its IP address from a different DHCP server.

This made no sense to me initially because I only had one DHCP server. Anyway, it turns out my Linksys router, which was in bridge mode with WiFi turned off, was still broadcasting its SSID and dishing out IP addresses. So I changed the WiFi name to something different and problem solved.

My system (5 Ones, Playbase, Sub, Beam) just did the same thing. Happily playing From TuneIn on one set of Ones that then stops. When I look from the IOS App, it claims there’s no Sonos anywhere. Open MacOS App and it’s all there. Reopen IOS App, and it’s all back.

They seem to have really gone backwards with the last update of so. Alarms also randomly appear and disappear. I’ve had to add the whole system back once and partial system another time by reboot several missing speakers. All since around the first of April.

Seems like an issue in the individual controller ‘discovering’ the Sonos system on your network. If possible, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Just as a note, there are several things unique to a device that is running a controller, like work profiles, VPNs and other apps which could ‘block’ the ability for the controller from reaching out to find the system, but I’m taking from your post, based on the ‘sometimes it’s the other way around’ that this isn’t the case, which is why I’m suggesting contacting Sonos.

Thanks, I will try the diagnostic route.

Thanks. I will do that next time it happens. It does seem odd that the more basic MacOS controller always seems to work, both for the system overall and for the alarms. Alarms are nearly always (but not totally) missing from the IOS app (both iPhone and iPad) nice the April update. My whole system worked flawlessly until that update, even through the initial “new app” mess last fall

By chance are you using a modem/router box provided by your ISP and you have another router connected to the ISP equipment using the same SSID and Password for both the ISP gear and the other router?

If so, you have two networks, and both show the same SSID. Therefore, your Sonos is “network hopping”. Assuming that is the case you need to have your ISP place the router portion of their gear in “Bridge Mode”. That will eliminate the ISP network and place Sonos and all Wi-Fi products on the same network.

Well, it could be the Sonos, or the phone (either of them).

An interesting possibility @AjTrek1, I do have two wireless networks and can set at least the non-ISP one to bridge mode. One possible complication is that I also have a Boost that might be serving that purpose (or further confuse it).

I’d recommend setting the ISP router to bridge mode. I prefer to use my own router as I have more control and have the ISP router set to Bridge mode. No offense intended...but setting your personal router to Bridge mode and not the ISP’s kind’a defeats the purpose of investing in a personal router. JMHO 😊

The Boost would not cause such a problem as it is a proprietary 2.4Ghz band (SonosNet) and nothing else can connect to it except Sonos. You can still see your Sonos when it’s on the Boost network as it (without being too technical) piggy-backs on your home Wi-Fi which is why it must be wired to your router.

However, outside of creating two confusing networks (which it doesn’t) the Boost is obsolete. Wiring a speaker to your router is the now preferred method when the SonosNet is needed.

Hi, just for clarity I do have a boost wired into the network, and my isp’s router is already set to bridge mode.

Just been thinking about my set up. I think this started happening when I bought my Eero routers. I set my ISP router to bridge mode and hard wired the Eero into that. Then the other two Eero’s are connected wirelessly to the primary.

However, the Eero cannot take anything hard wired so I still have my Boost connected directly to the ISP’s router. I wonder if that’s the issue?
