There have been many issue on the Apple forum after the upgrade to iOS 14. I too ran into issues but it was the session timeout bug on the 9800 controllers being set to zero. What I would do is disable private address and test. I have that disable on certain SSID’s I have running at home. Then I would test with a new test ssid. First start out with just open and don’t enable any features, make it basic as possible. Then go to wpa2 psk and again test. See what works and doesn’t.

i already applied those steps and configure new open SSID without any enabled feature and still the same issue

1. Also try to turn on Airplane mode and after 10 sec turned it off!

2. Did you setup the DNS in your DHCP pool, When a APPLE device did't get a DNS ip address, it would consider itself offline and don't show the WIFI icon.

As long as your device gets a dhcp address and can access or see devices on the same subnet, then wireless is working and the issue is somewhere in your infrastructure. If you have other devices that work and or other iPhone or iPads working fine, then it’s that one device.
