sonos app on ios 16.6.1 frequently showing cannot connect

Hi, I have a Sonos arc and subwoofer. I have the Sonos app running on ios 16.6.1. The app very frequently disables the Account, System, Services and Voice and shows the cannot connect to the arc and subwoofer. There will be a period of minutes and then it will enable the options and then connect or ask me if I want to reconnect everything. In the mean time I am listening to something on the arc so actual playback is not affected. It seems as though there is a periodic connectivity issue between app and Sonos system which is frustrating when I want to use the app to change songs. I have ensured in iOS that the Sonos app has Local Network enabled but that in itself hasn’t fixed it. Anyone any ideas please?

The Arc always connects to 2.4GHz.

If you’re able to configure the router to use two different SSIDs (WiFi network names) then you can obviously force your phone to use the 2.4GHz one. (Turn off the iPhone’s Auto-Join for the 5GHz SSID.)

Out of the box many home routers now “helpfully” have a common SSID across both 2.4GHz and 5GHz, and use a “smart connect” (or some such) approach to decide which band to connect the phone to. If the router is deficient in other respects -- e.g. not forwarding traffic transparently between bands -- this is “unhelpful” for a system like Sonos which relies so heavily on intra-LAN comms.

Ok I’ll look into this and experiment.
I think you’ve nailed the problem thanks for your help.

Excellent advice from others. Here’s another possible issue with your iPhone which is storage.

Go to Settings > General > iPhone Storage

If the iPhone storage is close to being maxed out the Sonos App can’t load properly. One way to free up storage without deleting anything is to Optimize your photos via iCloud (assuming you’ve setup iCloud storage beyond the free 5GB).

To Optimize photos > Go to Settings > Click on your name > iCloud > Photos > Optimize iPhone Storage

The process is not instantaneous and will take some time to upload to iCloud. If you’ve already set photo’s to optimize then you’ll have t consider deleting apps and their data and/or removing old messages.

As I said earlier the above is only relevant if the issue happens to be related to your iPhone storage.
