I installed ubuntu from the windows installer yesterday. I tried for hours to get the wireless to work because the router was in another room and since the computer I'm trying ubuntu on is a desktop, I really didn't feel like moving it. I looked on forums, youtube, ask sites, and etc. I tried just about everything I came across.
Finally I asked my dad for the Ethernet cable and moved my desktop to the router and tried it that way, but it did nothing. So I looked online for help about the Ethernet connection, tried everything I could that way for hours as well and still nothing. I eventually had to stop otherwise I was going to rip my hair out.
