lagging

I have had Sonos for over 12 years, very reliable until the app update earlier this year. 
now it’s slow, volume change is slow, sometimes it doesn’t even change level even though app says it has. Music can suddenly stop yet app says it’s playing. 
System has been on same Wi-Fi for years. with no updates from Sonos on these issues being fixed anytime soon, Sonos  is not enjoyable anymore.

I think because MDNS is being used to connect to Sonos devices that reserved IP Addresses are not necessary.  MDNS resolves hostnames to IP Addresses.

Is the MDNS used to assign IP addresses? I thought it was only for looking up name / address pairs.

My DHCP server is still showing regular request/grant entries for my Sonos.

My issues with DHCP assigned IP addresses and Sonos all occurred at initial install, power fail or update times.

I didn’t even power up my last set of Sonos before using the MAC labels to set up the reserved IPs, may have been unneeded now but it was my first ever “first attempt succeed” install.

I don’t have IPv6 so I can’t tell what Sonos is doing in that space.

I don’t think Sonos has implemented any IPv6, have they? I thought they were relying, so far, on its backwards compatibility. Have they implemented new code on newer devices? I suppose I should go look at the FAQs. 

Was just looking at the Arc Ultra, which says it is ‘compatible with WiFi 6’. Not sure what that really means, but isn’t WiFi 6 (IPv6) backwards compatible with IPv4? I’m not sure what that really means, but I’m fairly certain ‘older’ products don’t have cards in them that support iPv6. Now I need to do further reading….

Huh. WiFi 6 is the 802.11ax protocol, and has nothing to do with IPv6. Wonder why I was conflating them in my mind.

A touch of left-over “Christmas cheer?”

Lots of old posts on IPv6 but no definitive answers from Sonos.
