my iPhone 12 is killing my home internet across all my devices

I have no idea what is going on. But for the past month I've noticed our internet suddenly halts to a crawl. And I've noticed if I turn off the wifi on my iPhone 12, then suddenly all the devices throughout my house start working again. When I turn back on my Wifi on the iPhone it doesn't immediately cause the issue. But sometimes as much as a few times a day this will happen.

Does anyone have any idea?

Sounds like your router could be the problem. Is it provided to your by your internet provider or one you bought?

This. Sounds like your router is giving priority to your iPhone.

Interesting!? It was provided by my internet provider. Do you know if there’s anything I can do!?

Thanks, do you know if there’s a way I could change this? Oddly, even on the iPhone this behavior causes its internet to freeze up along with all other devices on the network. So if it’s giving a priority to the iPhone it’s still causing the internet to grind to a halt until I turn WiFi off and then everything instantly goes back to normal (including the iPhone which would then be using cellular)

One thing to try, although it may not make a difference…The default for WiFi on later versions of iOS is to use a private address. Try turning that off in WiFi settings.
