Hi,

 

I posted this issue in the past but the problem is coming back: 

 

Issue:

  • After 24h (sometimes just a few hours) to 48 hours the SONOS speakers stops playing and impossible to reconnect to the speakers.
  • When it stops playing the SONOS speakers still appear in my router devices’ list as still connected (as shown below) but SONOS Apps (iOS, Android or MacOS) do not “see” the speakers anymore.
  • The only solution is to reboot the router or change the 2.4Ghz channel (which I believe reboots anyway the router).

 

My systems (2 items):

  • Sonos Connect:Amp (1st gen) connected via 2.4 Ghz (note: This is not 5Ghz compatible)
  • Sonos Play:1 connected via 2.4 Ghz
  • I forced both on 2.4Ghz as it seemed to have solved the issue in the past. 
  • Both systems are updated.

 

Router:

  • TP-Link Archer AX10 
    • Firmware updated
    • I have a Mesh but even without it the problem occurs. To be safe I changed the Mesh’s SSID to force the speakers to always connect to the router’s 2.4 Ghz which has a unique SSID. 
    • The router and speakers are just a few meters apart.
    • For the 2.4Ghz band I’ve played around with all options:
      • Manually change all channels (from 2 to 13) or put it on ”auto”

      • Channel Width: 20Mhz, 40Mhz or auto. Same problem. (Note: 20Mhz is recommended by Sonos)

      • Security: WPA2-PSK

  • I did a MacOs scan which recommended channel 11, but again I played the entire band or “auto” without much success.

 

Latest tests

This is highly frustrating as you can imagine.  I keep on doing heuristic tests by changing settings, for instance just before posting this message I disabled “OFDMA” and “TWT”…. which I am pretty sure I did in the past but still keep on trying:


Question:

  • Will buying a more expensive router and/or a different brand help? I saw quite a few posts about TP-Link and SONOS. Not specifically my model but TP-Link in general.

Before you do anything time consuming or complex take a shot at the simple solution that has helped so many other Sonos users.

Go to your router’s DHCP page and assign a static/reserved IP address for each Sonos device. That is usually just a couple clicks per device and the whole process takes just a few minutes.

Once done power down all Sonos.

Reboot the rotuter.

Power up the Sonos. You can check the Status to see them on the new addresses.

Thanks Stanley. Sorry I forgot to mentionned that I have set up static addresses to the speakers. The problem occured today like almost any other day. 

If I may add, I rebooted and everything works but it won’t last.

With the static addresses in place I’d submit a diagnostic with everything working to establish a baseline (note the number) then wait for the issue to happen and within 10 or so minutes submit another diagnostic. Contact Sonos support to have them looked into.

The 24/48 hour thing really had me looking at DHCP though. 

Thanks, never thought of this but going to do it now. 🙏
