It seemed that everything worked for me -except- the wireless that is
my only link to The Internet...........

It's a long and very involved path to try to fix that. Which falls
apart several steps into the process of trying to fix the settings in
ubuntu, per the directions.

That's on new Macs....... It seems I have to have a separate, older
ex-Windows machine to use Ubuntu and be able to get On-line as well
as access my other computers.

Someday I'll try to fight my way through it again in the hopes that I
can have fully working Ubuntu/Mac/Windows computers.
