It's not about iOS14, is about the WiFi module the Apple use, if your iPhone/iPad use Murata WiFi module, then have the WiFi issue, but if the WiFi module supplied by USI have no WiFi issue. It's a hardware issue, not a OS issue, so don't expect Apple will fix it via OS update, that's why Apple keep silent about this issue.
I have tested many iOS devices, iPhone 6, 7, 7 plus, iPad Pro 11, iPad Pro 12.9, iPhone 11, 11 Pro , those devices which use Murata WiFi module have the same WiFi issue, but others use USI WiFi module have no issue at all, all of those devices are update to iOS 14.2
