Le Pingouin, the file does exist, although it is one level further down the directory structure, ie /etc/wpa_supplicant/wpa_supplicant.conf. The instruction webpage referred to in my post #1 has you create the file and it's contents, see the page and look almost exactly half way down.
Is the file in the wrong location? I can move/copy it if you think it might help.
Thanks, Rans6...........
