Ever since I upgraded to IOS 14.0.1 I am having huge difficulty maintaining a wifi connection. There was absolutely no problem before. I have iPhone 11 Pro Max. If I 'forget the network' reboot the phone, and then reconnect to the network I can connect using wifi. But, shortly after the phone being idle for any period of time, i have the same problem It's annoying to have to go through all of this just to connect to the wifi. This is happening in every location I'm at so it's not a problem with my home wifi.
Wifi problems
The issue is ios14. It has a serious wifi glitch that only apple can fix. However they have had plenty of opportunity to include a fix in their iOS updates and have failed to do so.
