iPhone 12 Pro Max 12 Pro Max Wifi Keeps Disconnecting

[Spetsgruppa]

So i recently noticed that my 12 Pro Max is continously disconnecting wifi when cellular data is turned on. But doesnt disconnect if i put the phone into Airplane Mode then connecting it to the wifi. Is there a “smart switch” option im not aware about?

My 12 PM is currently on IOS 15.4.1.

 

[now i see it]

It shouldn’t do that. There’s no special toggle switch to prevent it.

Mine has similar behavior. WiFi disconnects every time the screen locks. And reconnects as soon as I unlock the screen.

Maybe you have poor WiFi, or your iPhone thinks you do. I have 'Wi-Fi Assist' setting turned off:

About Wi-Fi Assist - Apple Support

With iOS 9 and later, you can use Wi-Fi Assist to automatically switch to cellular when you have a poor Wi-Fi connection.

Been having the same on a vanilla 12 Pro since iOS 15.0 despite being feet away from the router with a perfect Wi-Fi signal and no network problems on any other devices. Most commonly it switches to cellular for FaceTime. Having read the other posts here I think it’s a bug in Wi-Fi Assist. I will try disabling it ?
