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

..,and the issue seems the same whether using S1 (one household with one legacy Play 5) or S2 (three other households).

Ken’s earlier post about checking ‘Private WiFi Address’ is probably a good one.

As stated, I’ve not had this experience, and I’m also 90% Apple, with two iPads, an iPhone, and two Macs in use. For S2. 

I’ve always done the same, both with an AT&T connection, now with a Spectrum device. 

I don’t use an ISP provided router (other than as a modem), as you usually only get what don’t pay for with those ‘free’ devices anyway.😂

...and whilst BT routers are regularly complained about online, often in regards to SSDP multicasting ‘device discovery’ across it’s wired/wireless segments, with some firmware updates. I think we can be safe in the knowledge anyway here, that each Sonos system is running on SonosNet using a Boost as its (likely) root-bridge. Although I guess DNS/QoS issues etc; have not (yet) been ruled out.

I’m thinking it would be interesting to try an Android controller device with each Sonos system, as it might be something on the iOS devices, like ‘Private WiFi Address’ or even the recent Home(Kit) App upgrade, that Apple ’quickly’ withdrew because of it causing problems with various smart-home products, including their own HomePod speakers.

Next step might be to borrow an Android device to see if the Sonos App search provides much faster results. Then perhaps hone-in further on the Apple controller devices.

Unfortunately, based on many years of frequenting this forum, I’ve noticed a rather large amount of issues with BT’s hardware. If I ever move to the UK, I’ll be certain not to choose them as my ISP. 

As a throw away comment, I do have to wonder if perhaps BT pushed out some sort of update to their routers that might be contributing to this. 

I’m a US user, and not seeing this altered behavior either. 

Hi thanks once more - the 73 Mb/s is a very solid download speed for most households in UK - must don’t yet have fibre to property - and it,or lower, has for many years been more than adequate for Sonos applications.   The key thing is that the fault is being experienced in four different regions of Uk with different routers whereas previously there was not an issue with the same set up.  The only variables before and after appear to be iOS and Sonos software updates 

Thank you - not sure how I change the DNS server - all properties use BT routers on BT contracts as internet provider but are geographically hundreds of miles away from each other. 
 

it is effectively as if four separate households were experiencing the same issue, the only common connection being all Sonos players are identified as belonging to my account (but set up as four separate households systems) and the same issue arises whether S1 (one household) or S2 (three households) are being used, by the same (this iPhone 13 or my wife’s iphone13 which move between properties) or the iPads which remain as controllers in the specific properties.  The only controller which works as normal is the iMac (on an S1 system). 

Hi - thank you.  However it’s unlikely to be wifi interference since the same situation has only recently arisen in four different distinct properties, each of which has behaved impeccably before.  Moreover, the issue is the same no matter what the distance from the controller device (app) and the boost.   No other WiFi issues eg interference which has necessitated change of Sonos channel.   The fact that I’m experiencing the same issue, using various app carrying devices, in four separate geographical locations with different WiFi networks suggests to me some glitch between the Sonos app and iOS software version.   IMac controller nit experiencing the same issue even though furthest away from the Boost.  Even within a couple of feet the iOS devices still  experience issues  

Hi

I’m having similar issues - I’ve four systems in four locations using separate WiFi networks.  Three use S2 and one S1. Very recently, ALL apps (irrespective of S1/S2) are slow to respond to volume changes and to load search results - Amazon Music/ Hype Machine results returned seemingly instantly but Quobuz and Spotify(My go to choice) take twenty seconds or more to return results.  Using iPhone 13 iOS 16 generally but elsewhere iPads 6s or 9s using latest software.  Sonos software up to date.   Each system uses Boost for network and has 73 Mb/s BT internet.  Disconnected and reloaded S1/S2 Apps but issue remains.  Search results used to be returned almost instantly.   iMac controller still functions as it should with no delay.

I would like to add my concerns. It seems to have gone worse recently- Nov 2022. It seems to struggle to produce my recent playing history. In S1, i deleted this function, but cannot with S2.

As I am not suffering short-term memory loss so this is a completely useless function, in any event. I would much rather be reminded that Ii have not played Album X in the last 2-years, or similar. Sonos is collecting data for no useful reason.

Device discovery is entirely the same whether it is S1 or S2. Your router is by far the most probable cause, please tell us what kind it is (and whether you are using WiFi [likely] or SonosNet [less likely].

Device discovery is:

SSDP broadcast (3 seconds per UPnP spec)

SSDP multicast (3 seconds concurrent with broadcast)

mDNS search (concurrent)

When a device is found (on the correct Household) then it is scanned for services, and the interesting services are subscribed to. Some UPnP calls are also made to each device.

That is all local network device-to-device calls, and as we have seen too many times, some routers suck at this.

None of this has changed between S1 and S2.

If using a PC or a Mac then there are some human-readable logs generated which might give a clue. On all devices you can always generate a Diagnostic for Sonos support to take a look at.
