I just went thru a week of trying to figure out what went wrong with Ubuntu.
first of all, before doing anything go here http://www.ubuntu.com/certification/desktop/
if you don't see your computer on the list, forget ubuntu. (if you bought a toshiba with win8 and don't like win8 do a google search for "Classic Shell', that's a safe, compatible little program that turns ugly win8 into win7, easy.)
of the hundreds of messages I've scoured thru to find some info and pointers, this is one of my favorites--
it starts with, "I want to access to a wireless connection in a PC with linux (ubuntu 10.04). But I can't find any connection."
Rickie answers with, "Weeks after weeks ppl keep asking this question. The answer is because you are using a free linux that mostly relies on opensource technology and insanely restrictive laws in the USA do not allow to integrate proprietary drivers in open source technology.
Ubuntu is a cute little linux but a nightmare for ppl using wifi, forget about installing the drivers yourself unless you are a programmer".
then Alessandro T gives a pointer to the Ubuntu Forums and some links for programmers like, https://help.ubuntu.com/community/Wi...er/Ndiswrapper
