Hi Team,


Already have read almost every forum post and tried every trick from completely reinstalling all my Sonos devices till completely redesigning my wireless.

Iam using a arc with a sub and just replaced my Sonos Play 1 surrounds with 2 ERA 300 devices.

The problem is they keep losing there connection in the surround enviroment and i don't get it why. 

There is not a real error but sometimes after 30 minutes and sometimes within 3 minutes the ERA300 speakers disappear in the app and I cannot get them back.
I tried reseting them, unplug and plug the cable again.

Also set my wifi to only use 2.4ghz, 5ghz, disabled things like client loadbalacing, band steering, added fixed IP addresses etc etc.. but iam pretty lost now.

Iam at the point of returning them because my play 1 were always working fine but for some reason its not possible to get a steady connection with the ERA300’s...(EDIT) added my play 1’s again..but they disappear now as well.. so not sure if its me / the app/ my wifi setup but please I need some help with this :) 


Use them in the same spot in my living room.

IF you need any additional information please let me know.

Huh. Lost a long reply on the other thread. 
 

Shortened version here.

This is, of course, a Sonos community, and not direct support. We don’t have any access to hard data at all. 
I’m leaning in two directions. First, a possible duplicate IP address issues. Try powering off all Sonos devices, and then reboot your router. Give it two minutes to come up before plugging back in your Sonos devices. The Era 300s, while they do connect to the Arc, also receive IP addresses from the router. 

Second is possible wifi interference. The electronics are different, it’s entirely possible the Era’s are reacting differently. Worth reading the FAQ and applying as much of that as feasible.

Lastly, I would urge 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 to add that your Era300s connect to the Arc using a dedicated 5ghz network to bond the speakers together and avoid lip sync issues. If you can try to avoid other devices or equipment around the home theatre area being on the 5ghz network, you might avoid any potential interference that might be knocking out the bonded connection.

Or change the channel number of the 5ghz network on your router as it might be conflicting with the 5ghz channel of the Arc/Era 300s.
