I have bridges and boosters, one day Sonos was perfect and then it disappeared. This has been happening for years, however for over the past month it has completely disappeared

Hi Annoyedbysonos,

It sounds like your BRIDGE is losing communication with your router from time to time. This may be due to a faulty ethernet cable, faulty ethernet port, or IP address conflict. Please start by swapping out the ethernet cable and see if that helps. You can also try swapping ethernet ports on your BRIDGE and Router.

If the issue remains, try wiring a different Sonos unit into your router and see if your system returns.

You can also try the steps outlined in this FAQ.

If none of these steps help, please let me know and I'll create a support ticket for you and get you in contact with our phone team for further troubleshooting.

thank you I will do that
Guys! I've had problem with "Your sonos was not found" all the time and seems that I found a solution!

My router has 2.4 ghz and 5 ghz wifis on by default. It turns out that Sonos were using one standard while my phone would use the other one.

What I did is I turned off 5 ghz on my wifi router (because I'm using some older equipment that doesn't work with 5ghz) and using 2.4 ghz wifi only now. Worked like a charm! My iphone 6 connects to Sonos system immediately every single time!

Try to fix your router settings and make your Sonos system great again!

The software is uncapable of finding out if the controller software is communicating through 2.4Ghz networks while the equipment is on 5Ghz networks and vice versa. In 99% of the cases I simply had to switch my Ipad/Iphone to the other network to get a connection.

IP address conflicts, none. All equipment has been given IPs through DHCP as could been seen in the clients table in the router. No conflicts either.

I have quite alot of networking equipment but the Sonos equipment is the only one causing issues. The software is simply mediocre.

Are you asking for help or is this just a grumble. I can't tell from your post.

By the way the SonosNet operates on 2,4 GHz. It uses the 5 GHz to connect sub and surrounds to Playbar. If your Idevice connects to YOUR wi-fi's 5 GHz network then that isn't Sonos' fault.
The software is simply mediocre.
The Sonos software simply follows the established UPnP standard for device discovery.

The 'mediocre' part is where some routers fail to forward such traffic between their 2.4GHz and 5GHz segments.

my sonos disappears and reappears, very annoying, however, when it is working we love it! Yes, I understand it is my network that drops it, and then finds it.

Well, that right there is your problem. Sonos doesn't communicate with your router in the 5 GHZ band. Unfortunately, with Sonos in WiFi mode (no wired Sonos components), most basic routers separate the 5 GHZ and 2.4 GHz into separate segments. So your devices on the 5 GHz WLAN can't communicate with devices on the 2.4 GHz WLAN, and Sonos is exclusively on the 2.4 GHz WLAN.

Actually, the software is quite robust. You are just using it at its most basic level, with a basic router. For a worry free install that will use both the 2.4 and 5 GHz WLAN, connect one of your Sonos devices directly to your router to activate the Sonosnet mesh mode. If one is not convenient to your router or a LAN port, get a Boost for the wired component.

The diagnostic is showing a lot of wireless interference on the BOOST. Have you tried changing the wireless channel on your Sonos system?

Also, make sure that the BOOST is not right next to your router or any other wireless device, like a cordless phone base station. A few feet is good, more is better.
