iPhone X problems

I was mentioning the other day how stable my iPhoneX.

Have you tried telling it to forget your home wifi in iPhone settings...reboot router and phone...add back wifi to the iPhone. Its possible that with ios updates your router has multiple IP addresses assigned to it (common issue with ios devices).

Yeah done all that - reset the the network settings on my phone and restarted the router this morning but it's still happening

do you have 2.8 and 5ghz networks. Does it make difference being on different one?

I have both but I am of the understanding that Sonos One only works on 2.4? Do you mean does it make a difference which one my phone is on? How do I select this?

Your controller can be on either. Try the 5.0ghz connection and see if that gives you better stability and less interference.

The speakers themselves operate on 2.4 but that doesn't apply to controllers connecting to the router.

OK, thanks. How do I set the connection for my iPhone?

I'm connected with my iPhone X via 5ghz (just checked). So maybe that is why its so stable for me.

Maybe the iPhone X is susceptible to wifi interference and the 2.4ghz band has so much that it drops.

Just go into your iPhone settings....wifi settings. I assume you have separate 5.0 and 2.4 ghz. Tell phone to forget the 2.4ghz connection and then connect to your 5.0 ghz network.

No changes within Sonos need to be made. Sonos doesn't care how your connected to your router by your phone.

I'm connected with 5ghz. However after looking at by BT Whole Home set up I see that my Sonos One is appearing twice with two different I P Addresses and different names which may have been a result of me trying to 'fix' Sonos when reconnecting it to the router directly and setting it up again. Is there a way to reset the wireless settings completely without doing a factory reset?

I would go in to the BT settings and give the Sonos One Mac address an brand new IP address (not one of the two you see it currently having). Then reboot the Sonos one and it should pickup only the new IP address and be fine.
