Dear ppl,

Not sure if this is common knowledge here, but my dealer informed me that a router/switch setting might cause Sooloos zones to disappear in the Sooloos app. I have experienced this phenomenon a couple of times in the past year or two and it very, VERY annoying. It occurs occasionally but not with a predictable frequency. When it happens it often occurs a few times in a few minutes.

I don’t know whether the dealer is correct or not, but it doesn't hurt to try: the suggestion was to ENABLE the IGMP snooping setting on all the routers and switches present in your network. Enabling IGMP proxying allows multicast traffic to enter your local network.

Like I said, I don't know whether this will cure the disappearing zone problem but it can't hurt to try.

Cheers,

Edwin

That's the well known multicast issue - doesn't affect most basic switches as by default they treat multicast same as broadcast so it gets copies to all ports.

Likewise with many routers, with most common issue being wifi based multicast traffic being significantly filtered to preserve battery life on handheld type devices by giving them more chance to sleep,

igmp snooping will only be an option on managed/smart switches and less basic routers. most household kit just does not have the option and you just get what you are given.

Hence why I always recommend a basic unmanaged switch with Sooloos connected direct to that - the switch just works out of the box and the router does not get involved - until wifi gets added to the mix.

Thanks Ian for your reply and apols for my late response. I thought my Netgear GS108Tv2 switch was a simple switch?

The datasheet for this switch says: ProSAFE® 8-port Gigabit Smart Managed Switch. Not quite a simple switch, I'm afraid.

Thanks, that odd: when I choose this switch (years and years ago) the site had it listed under the unmanaged switches.

I changed the managed Switch for an unmanaged one (Netgear GS116) but this morning one of the zones disappeared again.

Since an update (I guess a Sooloos Core update) the music starts playing again automatically after the disappearing zone reappears in the zone-list. In the past the behaviour was different: a disappearing/reappearing zone would be quiet until you hit the play button.
