Wifi connectivity on iPhone XS
I have an iPhone XS. Last week it started to lose its wifi connectivity constantly. My other Apple device (ipad) is fine. I have checked the router and rebooted and that is fine plus all other wifi devices are working as usual.
I have followed instructions to ensure wifi is connected properly on my iPhone & I have done the long list of switch on/off, reboot, toggle wifi button etc.
As soon as I notice the lost connectivity I go into wifi and selected router and it finds it ok. But it no longer stays connected.
All help welcome.
Thank you in advance.
iPhone XS, iOS 16
