My sonos connect, since moving to S2 recently, has started to drop from my LAN (only connection, WIFI is disabled). Both ethernet ports have both their green and amber LED light up solidly (not blinking), even for the unused port. I can still see the (correct, fixed) IP address occupied on my router software (Unifi) but the Sonos Connect is otherwise dead, my IOS lists the connect as Not Connected, and I am unable to reconnect through the software. This happens around 15 minutes after I reset the connect (power off factory reset). I have already replaced my ethernet cable and power cable to no avail. What can be the cause and how do I fix this??

+17What are the ports connected to? There should only be one port connected to your router/network.
Can you see the internal web server?
(use your IP here, not mine)
Unnamed Room (RINCON_949F3EB8553A01400)
Living Room (R) (RINCON_7828CAAF955001400)
Living Room (L) (RINCON_7828CAAF959C01400)
Network Matrix
My Living Room R+L is a pair of Play:1 speakers that work fine (also on fixed IP addresses, via wifi) and Unnamed Room is (I suppose) the connect itself.
Below are some of the diagnostics I can see (when connected), not sure if this points in any particular direction.
Your help is appreciated.
I’m not sure if this will assist, but…
Have you set the router to support multicast device discovery? - I’m assuming your Sonos controller device is just having difficulty discovering your ‘Connect’ on the LAN subnet. See this from the router manufacturers website:
https://help.ui.com/hc/en-us/articles/18930473041047-Best-Practices-for-Sonos-Devices
There’s also this link mentioned (found via a search here in the community)…
The link check was to see if the Connect was actually working after the Factory Reset, the actual data is of little use. Since it appears to be functional and communicating on the LAN that rules them out as problems.
After the Factory Reset (how I hate the mess that usually makes) did you go through the process of adding the Connect back to your system or is this where things are failing?
If it added back in without issue but isn't being found a network refresh is sometimes helpful. Power down all Sonos, reboot router and Controller, power up the Sonos. You do have static IPs set for all?
If all of that is working but you still have issues then Ken's suggestions would be my next try.
Thanks
Connect Gen 2 drops connection
I am considering sending my Connect gen2 to the people at Isonatec in Germany as it seems like a hardware failure. Maybe I need to downgrade to S1 as the most recent firmware seems to have memory or memory leak issues.
Without a Connect (or expensive ‘Port’) unit my Play:1 speakers become pretty useless in a HiFi setting as they are not compatible with Airplay2 and they have no line input, so the only way to get audio from my AV Receiver to them is via a Sonos solution. Pretty disappointed with the reliability after “updates”.

What happens if you take the Switch out of the equation and just cable the ‘Connect’ direct to the router?
The flickering light is not good.
Compare repair prices to other options.
Why not use one of the less expensive Sonos options that offer a line-in? A Era 100 and adapter would be my first choice.
A used Connect is also possibility.
Port lights illuminating with nothing connected indicates a hardware issue. As I recall the lights might flash briefly during a reboot.
I probably made the mistake of accepting the upgrade to S2. My Sonos system had been boxed away for two years and I wasn’t aware of the S2 debacle - just read the WSJ article on Sonos woes and just how unreliable S2 seems to make legacy systems. I was just able to downgrade my Play:1 stereo set (used as a wireless “zone 2” set with a Denon receiver) but my Connect definitely seems toast, probably the ethernet/wifi hardware. No matter how often I reset it or how I connect it to my network, it drops connection and bricks the network connectivity, with the aforementioned solid port lights. Repair or replacement seem the only remedy for now. A pity a new Sonos:Port unit is so expensive for what it does (inserting an analog line input on the propriatory Sonos network). Airplay2 is not really a practical alternative it seems as again there are no analog-to-network input devices (except improvising with an old iPhone/iPad). Of course even professional audio over IP solutions like Dante steer away from WiFi, probably for the same reason that it is hard to make these things reliable and foolproof.
Happy to report I had my connect repaired by https://www.isonatec.com/ in Germany (it seems they replaced the ethernet card) and downgraded back to S1. It now works as it should, and my system is stable for 3 weeks already, with lower delay and no lost connections. I can recommend Isonatec for anybody in Europe wanting to give their Sonos products a new lease of life.
