Hello Feartech,
SUCCESS!
Fantastic: the clean instal was the solution!
What about the EFI folder on the new BS USB disk?
Shall i copy the EFI from my Catalina internal SSD which is the same than the one on the USB stick used for the installation?
;-))

never used it but from here:

Installation | OpenIntelWireless

Documentation for OpenIntelWireless

openintelwireless.github.io

and i think that AirportItlwm.kext works for Big Sur but you will have to check on that

hello
found this on another forum "how to Force IO80211Family.kext to load:
<dict>
<key>BundlePath</key>
<string>IO80211Family.kext</string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>

Please @Feartech let me know what you think about this solution?

'intlwm.kext + Heliport.app' is not bad on Big Sur.
I use Dell e7250(opencore) + intel 7265/ Lenovo x250(opencore) +intel 7265 / HP 850 G1 (opencore)+ intel 7260
but I turn off bluetooth because not stable
If 'intlwm.kext + Heliport.app, the boot time will increase a bit.
