I don't understand why I didn't see the file "wicd.desktop" with the folder explorer (with 'show hidden' selected'). I found this file by searching in the terminal with "find / -name '*wicd.desktop' ". Do you know why?
You probably did not enter the proper search path. By default search is limited to the users home directory and its subdirectories. You can change that and start in the main system directory which has the slash / as symbol. So replacing /home/username with / would result in searching the whole system. (may take some time though)
Can you provide the result of:
cat /etc/group | grep netdev
Still puzzled about this whole thing. Too many failures , I'm starting to wonder if your Live USB was maybe damaged or the download incorrect. Did the md5sum match?
When you boot the live CD/USB there is an option to check the distro integrity. Does this show any issue?
Another question, any particular reason why you have Bodhi 3.2.1 instead of Bodhi 4.3.1?
