Sonos system losing connection to controllers.

Same problem here. Sonos controller frequently and intermittently loses connection with my playbar and Play 1 (music/tv will continue to operate fine). Just as quickly as it loses the connection, it seems to find my systems again. Running dual band router and changed the 2.4 ghz to channel 1, but still happening. Don't quite get it. Will expand songs network further to create 5.1, but this is ridiculous.

Hello Bentley82, welcome to the community.
I have reviewed your diagnostic and found peaks of WiFi interference. Be we start troubleshooting your network/router wireless channels. I would like to know if it would be possible to take the PLAY:1 and wire it to the router via an Ethernet cable. Once to make sure to also reboot both the PLAYBAR and router.

By doing this the PLAY:1 will play the role of a bridge between your network and the PLAYBAR. In short the Sonos system will make its own wireless network.
Test you system and let us know how it goes. Also, submit a new diagnostic.

Same here guys...
I have a lot of sonos equipment working flawless for years and since a few months its constantly loosing connection.
My controller says the sonos system was not found, from my iphone controller as well as a controller on my laptop. Alle sonos equipment is physically wired into the same network as my laptop which is also wired.

So it's not a network problem, I believe this all started a few software updates ago.

Very annoying!! And I am very disappointed.

I constantly have to reset the whole system and add one by one all the devices to the controller. It than works for a fews days, maybe a week or so, and the same problem starts again.

TRY THIS! (skip down to "SOLUTION" to get straight to what worked for me)

I seem to have fixed the constant issue of my controller not being able to find my sonos devices. Was frustrated beyond belief, so I hope this helps someone in a similar situation!

A quick rundown first:

ME: I am not super tech savvy, but can figure a few things out with enough googling. You don't need to be a networking professional, but do need to be able to access some router settings. If it sounds like I'm super smart on tech-y stuff, that's only cause I'm regurgitating what I learned while googling.

MY SETUP: Two Play:1's, each in it's own room. That's it. No Bridge, Connect, or the rest of the gizmos. My router is the Western Digital Mynet n750.

MY ISSUE: Pretty much every new time that I tried to play some tunes, my iphone 6 controller could not find the sonos players. Same happened with my wife's phone. "No sonos system found" or something like that. I'd try to run through the "connect to a new system" and/or "connect to existing system" steps to no avial, pushing the two buttons and watching that orange light flash and eventually turn white. Or unplug a speaker, and plug it back in. No dice. Eventually (if I didn't give up), I'd swallow my pride, go unplug and re-plug the router, and it'd usually work... until the next time. Sometime's if that didn't work I'd have to actually walk the speaker into the other room, and plug it directly into the router via ethernet cable. It still would only work until the next time tried to connect. So Frustrating!!

SOLUTION: ... [Not sure which of these changes is responsible, but It's been 2 weeks and I haven't had a lost connection since.]
Log into your router settings by entering its ip address into your browser url bar. If you have no idea what it is, try 192.168.1.1 as that's the standard for most routers unless someone changed it. For login credentials, try "admin" as the user, and "password" as the password. I think different router manufacturers have different defaults, so google what it is for your router maker. Then adjust these 3 things, which should all be under the wifi settings section (which might itself be in "advanced" settings):

1. If your router is Dual Band (2.4 and 5.8 Ghz), make sure you have a different name for each network. It's true that SONOS players only use the 2.4 Ghz band... UNLESS playing along with a Playbar as part of a 5.1 home theatre setup... which means they can access the 5Ghz band even if they're not using it. I'd set the same network name (SSID) and password for both bands, so I figured it was entirely possible that after some down-time it would try to reconnect and accidentally log into the 5 Ghz band since it's the same credentials.

2. The 2.4 Ghz network (the only one if you don't have a Dual Band router) Channel should NOT be set to "Auto." This is actually what I think is the most likely reason for the issue. Regardless, set it to a specific channel, either 1, 6, 11. Google it if you want to know why only those. This may not be as important, but I WOULD RECOMMEND setting it to Channel 1. Reason being that (warning- this is weird) your microwave might be interfering with the signal. Due to frequencies and other physics-y stuff I don't understand, apparently most microwaves happen to run at a frequency somewhere on the 2.4 Ghz, and channel 1 is the only one of those 3 (1, 6, or 11) that doesn't fall in the microwave range. (of my microwave at least, which I think is standard for most).

3. Set the CHANNEL WIDTH to "20 Mhz". NOT "auto" or "20/40". I don't really understand this one, but it was suggested by someone. What I did learn via another googling is that you're better off limiting it to 20 Mhz anyway (even if you don't have Sonos) cause it'll be less congested and you'll have faster wifi speeds cause the signal won't "stray" into the the other channels (6 or 11). Or something like that.

That's all I did, and I'm a happy Sonos user ever since. Hope this helps someone else.
Sure wish it was easier for me to figure out!

Cheers.

After years of pretty reliable service through bridge setup, about two months ago, our system started losing its connection to controllers - 2 iPhones and 2 iPads - pretty regularly, every other day. Trying to re-set/re-connect is generally unsuccessful until I send diagnostics from a couple of controllers more than 3x each, though it really just seems random. We have 2 Play:5 devices and a bridge which is wired directly to our Router (provided by AT&T for U-verse service). When I connected the newest iPad about a month ago (dropping pre-dated this but was not as frequent or frustrating), I went around to each device. Yesterday, system controllers couldn't find devices and I gave up and used an radio station's app to play...this morning after sending diagnostics yesterday, working okay fine (apparently).

Assuming you've fixed duplicate IP concerns by switching off router, all Sonos gear and ALL devices connected to network and then restarting router, wait, restart Bridge, wait then start Sonos gear then rest.

It would be worth checking the power supply of the bridge - Should be a steady 5,1 V DC - use or borrow a voltmeter to check this out. Monitor for at least a full minute and confirm it doesn't fluctuate

Hello,

As of about 6 months ago, I have also been seeing this issue more and more often. Up until about a week ago(changed my modem/router) I thought the issue involved my wireless setup. I am technically inclined; therefore history has proven that I typically attempt to ratify issues such as these on my own prior to seeking additional help. Here is my current setup!

Play 1 (Bathroom)
Play 3 (2) Garage/Office
Play 5 (Living/Kitchen/Dining)
Playbar+Sub(Family Room, connected to my TV)
Bridge(In my garage wired directly my router)

I was having some capacity issues, therefore my wireless setup has since been altered. I know run a Docsis 3.0 Modem, wired to a Netgear Router running dual bands (2.4 and 5Ghz). To avoid interference, I am only using my 2.4Ghz bands. My setup is in my garage, broadcasting the signal throughout a split level single family home. On the complete opposite of my home(I have 2 wireless repeaters at this part of my house) sits my Play: 5. Ironically, this speaker no longer gives me issues, along with most of the others. Instead the speaker closest to my router(literally separated by a wall) is my family rooms playbar+sub is having a connection issue. I have tried to master reset again, however if the issues reoccur I will have to contact and document this issue. $1400 in speakers makes me frustrated that it is happening. Very loyal to Sonos up to this point, and not looking forward to switching, unless it is necessary.
