Sonos, please update your ancient network stack

by Volker Weber


We love that Sonos keeps its old gear updated and functional. That is pretty much unheard of in this industry. However, there is one big omission. You really need to work on your network stack. Two problems:

  1. Every recent piece of malware used SMBv1 as its attack vector. If you disable it Sonos is unable to find its music libary anymore. No support for SMBv2 or SMBv3. This needs to be fixed ASAP.
  2. Your STP implementation is ancient. If you add Sonos to a network with smart components that use STP (spanning tree protocol) it messes up the network. Yes, you can fix the path costs everywhere else, but why don't you just fix it in your own stack? This discussion is already seven years old.

If you like to discuss this, you know where to find me.


Hours spent (wasted) configuring a switch (Netgear GS724Tv3) because when I plugged an ethernet cable into a Sonos component every flicking ethernet light became solid on every device in my house!

Yup. That is a network loop, probably a broadcast storm.

I have that switch as well, btw. And a Linksys LGS326P. There are a minimum of 50 devices on my network at all times here at vowe's magic flying circus.

It's a nice switch. One you plug in and forget about (well unless you plugin a Sonos device!). I think I might have bought it as you mentioned on here a while back and my existing switch had died.

Also: It is the year 2017. All devices with network interfaces should be using IPv6...

I had a very heated discussion about this. Summary: no way.

About IPv6? That would be quite dissapointing, and a clear sign that Sonos doesn't plan to be around in a few years.

It's bad enough that music services like amazon are almost unusable, but when even the technical foundation starts to age so badly...

Ein wenig Offtopic: Ich war heute mal so wahnsinnig, auf meinem Handy (ja, mein einziges) die iOS11 beta zu installieren. Spielt man dann Musik über Sonos ab, wird als Ausgabe "Lautsprecher" angegeben.

Darf man sich da leise Hoffnung machen, dass es eine Integration von Sonos gibt?

Johannes Matzke, 2017-07-22

That is a different topic. Sonos Controller does not play music. It only tells a player to play something on its own. On iOS 10 that same control says music is playing on iPhone, which also isn't true.
