once again thanks for great help!!
This has unfortunately not solved the issue. Still the driver was not loaded when booting. And I guess this is the real issue.
[ 5.372559] brcmfmac: F1 signature read @0x18000000=0x15264345
[ 5.390612] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6
[ 5.391647] usbcore: registered new interface driver brcmfmac
Therefore I searached the web a bit and tried following to understand if the driver is supported already. And yes it is:
[email protected]:~ $ modprobe -c | grep -i „7392.*7822“
alias usb:v7392p7822d*dc*dsc*dp*ic*isc*ip*in* rtl8192cu
I loaded the driver manually
[email protected]:~ $ sudo modprobe rtl8192cu
Now it also shows up at loaded modules
[email protected]:~ $ lsmod
Module Size Used by
rtl8192cu 86016 0
rtl_usb 20480 1 rtl8192cu
rtl8192c_common 65536 1 rtl8192cu
rtlwifi 114688 3 rtl_usb,rtl8192c_common,rtl8192cu
mac80211 802816 3 rtl_usb,rtlwifi,rtl8192cu
And it seems well connected, WiFi Stick has Blue LED on and I can access via WiFi with remote console! Great!

But the question is now: how to make sure that it also is done automatically while normal boot?
Any hint would really be appreciated!
Thanks a lot,
