Just reporting a bug really and doing it here as support chat has been impossible to get hold of.

Recently upgraded to Asus BT10 wifi 7 mesh system. All my other devices connected fine (including the ancient stuff like nest thermostats, ring doorbells, my 14year old printer etc...) with the exception of my Sonos gear

Arc, Sub3, symfonisks bookshelves - none of it would connect.

Trying to manually reset the network settings and ultimately factory reset didn’t work, it simply wouldn’t connect to the wifi network.

Ultimately I found that disabling ‘Wifi 7 Mode’ within the router settings allowed everything to connect back up.  Wifi 7 mode is backwards compatible with older devices, as proven by everything else in my hose connecting to it fine, just evidently not for sonos,  they will not connect whatsoever to an Asus wifi 7 router if Wifi 7 mode is enabled.

Hopefully this can make its way to the engineers and they can push out a firmware update for these devices to work fine on a wifi 7 enabled network, as even the most ancient of my other kit can do without issues.
