Hello everyone.
I have a very modest Sonos setup consisting of 2 Symfonisk table lamp speakers, which I am very satisfied with. If it matters, one is almost 2 years old, whilst the other is only a couple months old.
However, as of late, I have been having some trouble, with the speakers simply vanishing from the App, Spotify connect and AirPlay (they show on the list of available devices, but the iPhone or iPad can’t connect to them). This issue became much more pronounced since the last firmware update.
My home network setup consists of of a TP Link Deco M4 mesh system, working in access point mode, with my ISP supplied router handling the DHCP (can’t do it another way or I would lose the TV service). Two of the Deco mesh system nodes are plugged in by Ethernet to the ISP router, whilst the last is connected by Wi-Fi to the other 2. Both Sonos are connected wirelessly to the Deco nodes.
Steps I’ve tried:
Have one of the speakers (bedroom speaker) plugged in by Ethernet to one of the Mesh System nodes. The other (office) remains connected on Wi-Fi, but has a strong signal (my PC, sitting next to the speaker, is able to saturate my 500mb/s connection on Wi-Fi), so it’s not an issue of it being far from the access point.
Unfortunately, after a couple of days, the bedroom speaker would drop. Moreover, it was also making the router quite confused as it would wrongly report both speakers as being connected by Ethernet to the same node, despite both having different IP addresses and being connected to different nodes.
I’ve also tried keeping one of the speakers (office) unplugged for a week and test it with a single speaker only (bedroom). It was more stable, but after 5 days or so it also dropped or shows intermittently in the app.
I have had no issues whatsoever with any other devices in my network, be it TVs, consoles, PCs or tablets/phones.
How should I setup my system so that I can have both speakers working in a stable manner? Or what other steps can I take to diagnose the problem?
Thank you in advance for your help.
Best,
