Poor Wifi Connection (disconnection) and speed with 2.4 ghz and bluetooth issue
I bought an Iphone 11 pro and i noticed 3 annoying things about wifi:
1) The signal is weak than before, and where i used to use 5ghz now i can't because it is soo weak that it switch to 2,4 ghz
2)When bluetooth and 2,4ghz is on the download speed go down drammatically. I know that both use 2.4 ghz band frequency, but i've only a mi band connected and go down from 60 mbit to 2-3 mbit
3) When i unlock iphone i find my phone connected to cellular net instead of wifi.
So i tried reset network.
Disabled the option to switch to cellular if wifi signal is weak
Disabled wifi assistance in localization.
Any other idea?
iPhone 11 Pro, iOS 14
