Anyone else experiencing severe APP LAG & slow loading/refresh with S2?

Hello, 
I had latency problems on S2 with my Sonos system (Mesh network, with a sonos boost).
I changed channel 1 to 6 and the latencies disappeared.
Thanks for the info :) 

This looks like an old thread but the problem still exists for me.  Ive got 15 zones containing 22 devices.  On an Orbit mesh network in a city environment.  When I look at available Wifi networks there are between 19-23 available.  I know I have interference.  That is what I figure is causing my App Launch to App Usable massive delay.  As others have pointed out, opening the app and waiting 20-40 seconds for it to become responsive is VERY long especially if the music came on loud or in a wrong zone…  Airplay is rough as well.  Trying to play a high resolution (TV or QoBuz) source via airplay ALWAYS causes dropouts.  Trying to play same high resolution sources to ALL ZONES also causes constant dropouts.  My Orbi network is back haul connected via Ethernet and is probably one generation old (RBR50 Router) so still very capable.  I have called in to Sonos support countless times and if I get someone (usually during business hours) that isn't worthless, we kind of arrive at the fact that I have a LOT of interference on all channels.  This is something I have not been able to figure out how to get around.  My ultimate conclusion is all the delay in the app becoming functional after being initially opened is attributable to either 1, all the local interference OR 2, the fact that I’m on a MESH network.  Not sure if SONOS likes Mesh or if there is some configuration I could manage that would improve the network’s performance.  Right now though, using the Sonos app is horrible experience and I try to manage everything through Alexa - which is much more responsive than the native SONIOS app.  .  

Sonos works well with the chosen Home WiFi mesh setup here, which is Plume WiFi. I also use a wired backhaul, but I don’t have lots of ‘other’ WiFi networks nearby to cause the issues you’re encountering.

I’m not personally familiar with the Netgear Orbi mesh system, but my thoughts are that a good WiFi mesh system should be avoiding the other nearby networks and providing a good delivery of wireless communication, especially for the shorter range 5Ghz band, which most Sonos products will use these days (except Sonos Home Theatre devices, which I guess could be wired to a Switch off the Primary Orbi Hub)

Anyhow I have a similar amount of devices and zones and the Sonos App opening time is between 7-10 seconds from its fully closed state, that’s on an iPad Pro controller.

Maybe look at blacklisting your compatible Sonos products to force them to use the 5Ghz band and wire any others that use the 2.4Ghz band to a Switch linked to the Primary hub and see if that improves device discovery/response times and see if you can then get the App up and running at least within half the time it takes now.

Ken. Thanks for your response. I checked and all my wifi components are on 5G so would the blacklisting help?  My guess is that is to keep it off the 2.4 band. I do think it’s all about interference because I still use the matrix that Sonos says isn’t used any longer. The matrix does show a lot of noise / interference. Also, the poor performance with high resolution sources is troubling along with the inability to really do airplay consistently without a lot of errors. Any further advise would be awesome because I am figuring the blacklisting would only insure 5ghz which all are already on 

I don’t see any information in the Sonos matrix as I’m using the Plume WiFi - do you have a Sonos device wired to the LAN then and are you using SonosNet at the moment? 

Yes. I have two Sonos connects. Maybe that’s it. They are Ethernet connected. The matrix shows a decibel figure and some color coding. Fri. Those two things plus the way they are positioned you can see what is connected to what and how good the connection is. 

… oh and ‘yes’, the blacklisting suggestion was just to perhaps put all (or some) Sonos products onto the Orbi 5Ghz WiFi band as that band is less penetrating/quicker (more localised) and you could then also use the DFS WiFi channels etc. and hopefully avoid your neighbouring WiFi signals, but it really depends on what devices you perhaps have in your setup. 

Your Sonos matrix is not going to be that helpful if running all on your WiFi signal. It’s geared for use with SonosNet …and the more modern Sonos devices are not using its full features these days anyway. 
 

Ah our posts crossed - I have a few questions and a suggestion.

Have you tried running your setup with no Sonos devices at all cabled to the LAN? If not, then I would certainly give that a try, as Sonos has greatly improved in this area. What also would help is, if you can cable the Orbi satellites back to your Orbi Primary Hub. I accept that’s not always practical, but worth doing if you can.

Next ensure any ISP provided router is bridged (or better still put in modem mode, if that mode is supported) and that its WiFi adapters are disabled. 

I would then reboot all and let the system settle for a day or so and see if things improve.

Wow. So that’s interesting. Sounds like you are suggesting running all speakers in WiFi mode and disconnecting the Sonos connects. I could try that. My objective has been to try and cable more speakers via Ethernet. 
 

also. The Orbi satellites are cabled back to a switch then back to a patch panel to the main router. I could bypass the switch and just do a direct cable connection. 
 

finally my new IPS doesn’t require a cable modem so that isn’t a favor.  
 

I’ll give this all a try but find it hard to believe that wireless could be the solution vs a mixed bag or wired and wireless. Sonos has suggest I try to wire more. I may actually try to shut down any that aren’t wired to see if that improves things. They seemed to indicate that once I get past 5 in a group it could be a problem. 
 

thanks for your guidance. 

the app sucks!! I have 6 sonos amp and the app cant find them! . I was thinking it was something with my network, so I went to buy a new switch and router but we still have the same issues after installing everything new

it need to be S2 app, because spotify app find everything with not problem ..
