Hi there,

I have a Sonos Port and am having some major issues which are rendering it very frustrating - anyone else seeing the same / have any advice? Details below, cheers!

 

Device:

  • Sonos Port, with a turntable on the input and a pair of active speakers on the output

 

Issue:

  • Port will drop from WiFi every 4-5 hours or so and requires switching on and off to get it to show up again - it either disappears from the app completely, or will also occassionally just be identified as offline
  • When it does then connect, any other speaker which is not currently playing something disappears from the app (they gradually appear again over the next 15-20 minutes)

 

What I’ve Investigated:

  • Wi-fi Strenth - this is good (43 dBm), and the issue still recurrs if the Port is right next to the access point
  • DHCP - I’ve given the Port a static IP on my OPNSense router (doesn’t fix the issue)
  • Factory Reset and re-adding the port (doesn’t fix the issue)
  • Hard wiring to ethernet (fixes the issue but I don’t want to hard wire the device...)

 

I really don’t think this is a network issue and it’s only the Port that seems to cause these problems - something going wrong in the firmware? Increasingly frustrated with Sonos, particulary with this alongside the recent issue with the Alexa integration failing...

 

Sounds like the Port (or your phone) may be switching wifi frequency (2.4/5GHz) and your router can’t handle that. Temporarily disable 5GHz on your router to see if that improves this. If it does, reconfigure the router or get another one.

Have tried that also  with no luck - I’m using a set of Aruba InstantOn wireless APs which are pretty high end, and a separate OPNSense router / firewall which I have configured carefully. Think I’ve fairly conclusively ruled out an issue with the APs / router but thanks for the suggestion.

 

The thing which is puzzling me the most is that the Port is disconnecting from WiFi entirely (router shows it as offline), but connects fine as soon as rebooted...

I think there are basically three possibilities here.  The one I think is least likely, but certainly still possible, is a hardware fault on the Port.  Next is local wireless interference (not necessarily WiFi).  I still think the most likely cause is a network issue, probably related to the APs.  I assume they are i bridge mode?  Have you tried experimentally turning them off for a while?

The only way you are going to get to the bottom of this is to submit a system diagnostic immediately after a drop occurs, then follow up with a call to Sonos Support.

We cannot rule out a hardware issue. Submit a diagnostic before and after an ‘event’, then work with SONOS phone support.

I found I needed to set IPs for all my Sonos followed by a full rebooting of everything, S5, router and APs to get everything stable.
