Bugs in iOS 14.2 WiFi/WLAN implementation

iOS 14.2 clearly has some serious bugs in its WLAN impllementation! We have both an iPad Air and an iPhone 11 Pro showing miserable, unreliable WiFi performance. My iPad Pro 2020 running iPadOS 14 is working fine. We have tried many of the usual solutions (e.g. disable private MAC address, reset network on Apple device, reset router) without success. The most amazing result was when we tried the advice I found to turn on flight mode: nothing happened! Both the iPad Air and the iPhone 11 Pro show flight mode enabled, but WLAN and Bluetooth still turned on and WLAN still connected!

iPad, iOS 9

Thanks for the tip(s). My router was set to 40MHz BW for the 2.4GHZ band, and changing it to 20MHz seems to help.

However:

My iPad Pro 2020, my Lenovo laptop and my Samsung Note 10 were all working fine with 40MHz@2.4GHz.
Even the iPad Air and the iPhone 11 Pro were working fine with 40MHz@2.4GHz before we updated to iOS 14.2.
Outside the home, one has no control over what BW is used in the 2.4GHz band.
These devices should IAC be using 5GHz.
Flight mode should IAC turn off all radios.

So iOS 14.2 is still buggy, but thanks for the workaround.

P.S. I rejoiced too soon; WLAN performance is still quite unreliable in iOS 14.2.

I didn‘t find anything else to change in the recommended router settings.

Turning off Bluetooth didn‘t help either.
