I have this issue on one phone. it struggles to find the rooms, when it does find the rooms it then won't connect. All other devices my partners iPhone, iPads, computers work fine.

But this is the thing….this problem only applies to my iPhones going back over 3 maybe 4 handsets so is it something to do with the software passing onto each new handset when I do the changeover?

Help. Very annoying. Current handset is iPhone 13.

Thank you

Maybe it’s software on the phone, as you mention…

The Sonos controller uses SSDP to initially discover the players, multicasting via UDP to 239.255.255.250:1900 and, for good measure, broadcasting to 255.255.255.255:1900.

Thereafter communication is unicast.

If the multicast packets are being blocked, intermittently or otherwise, by something on your device, then Sonos device-discovery can fail.

You clearly backup your devices, if you have passed on settings etc. so maybe try a full reset and setup as a new device and see what happens, you can always return to your current backup after the testing is complete. If it turns out to be your mobile software, it’s a case of then trying to find the culprit by removing/re-installing suspects.

Just to say the SSDP discovery issues though can also be caused by the router or other local network devices in the subnet, particularly switches, other WiFi AP’s, extenders, powerline adapters etc. but the fact your partners devices work okay, seem to ‘infer’ that these things ‘may’ not be at fault, but I would not rule them out at this stage, as it might be a combination of things and there is such things as intermittent luck and coincidence, or just different models of hardware.

I would though, for now, concentrate on your phones software unless something else I’ve mentioned focuses your attention elsewhere.

Surely it would make sense to only reset the network settings as a first step?

It’s the fact it has occurred on the various devices and with iOS, I’m pretty sure the network settings are not backed up as the user usually has to reconnect to the WiFi network after restoring a backup IIRC (it’s been some time since I’ve had to restore a device🤔)?

It might be worth switching off ‘Private Address’, WiFi Calling and those type of iOS features however.

If only one controller is having issues, I suggest installing and reinstalling that controller. Nothing critical is stored in the controllers.

A reset device needs the first WiFi to be connected by the user. Restoring a backup will reload the other WiFi settings.

Consider deactivating iOS features like 'Private Address' and WiFi Calling. It could prove beneficial.

Setting up as a new phone I think is the way to go but it's the time and effort….will probably wait till my next phone. Thank you for your answer. Makes sense.
