My new iPhone 16 does not connect to WiFi
It initially worked for 6 hours, but I'm now without wifi connection. My MacBook is connected to the wifi, so the wifi is fine. For some reason, mu iPhone can not connect. The message I receive is that the password is incorrect which it is not. My router has a QR code that automatically connects the device to the wifi. I also tried to manually put in the password, but it does not work. I have rebooted the phone, but the problem persists. Older iPhones are well connected, but not the iPhone 16.
