WiFi is now working. Enabling the wpa_supplicant in debug mode revealed
that there was an old file /var/run/wpa_supplicant/wlan0 that it wanted
me to "delete" which I simply renamed.
I then proceed to running again but then I realized that I forgot to
kill the original wpa_supplicant which was automatically started.
Killing this process and issuing the wpa_supplicant directly from the
command line kicked things into life.
Thank you for your support highly appreciated.
