I recently installed an Orbi Mesh system. Things were working fairly well with Sonos but was having a couple aggravating issues and so I reached out to Netgear Support. One of my issues was that when listening to Apple Music, songs would occasionally stop and 5s or so later, the music would start again at the next song. As well, sometimes when grouping or un-grouping zones, I was getting an inconsistent response in the App. It would take too long to perform whatever operation I had attempted. Finally, in my 5.1 set-up the two Play 1’s and Sub were showing as disconnected but were in fact working (this is still the case). 
 

Netgear support had me change the MTU on the router from 1500 to 1460. They also had me change the 2.4ghz from Auto to channel 6.  I believe Sonos recommends the 2.4ghz to be on Auto? The 5ghz was already set to what she recommended. 
 

All of this occurred around the same time that Sonos also pushed out updates. My system does seem to be working better but I don’t know if it was the Netgear changes or the Sonos changes. 
 

Looking for some opinions, are these changes appropriate or should I switch them back to what they were (Auto and MTU1500) from a Sonos and Networking perspective?

Thanks!
