Wifi support for A83T?

My Banana Pi M3 is NOW connected to the router via WIRED cable, but nmtui-connect my-ssid gives me the following ERROR message: No such connection ‘my-ssid’ . From my posted issue https://forum.armbian.com/topic/10213-build-newest-linux-kernel-509-on-banana-pi-m3/, Wifi on A83T seems to be broken ???

Can anybody give me a hand please?

Cheers
