Hi, I am going to give you a zip file put it on your flash drive.

Down load the file to your flash drive then drag and drop the file to your ubuntu desktop.

Right-click it and select Extract Here. Open a terminal and do:

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/*  /lib/firmware/b43
sudo rmmod -f b43
sudo rmmod -f ssb
sudo modprobe b43

Just copy and paste the commands.

This should get your wireless working.
Thank you

Hello and thanks. I now have wireless. I guess, in a way, Ubuntu has a few more versions to create because there was no way an average user could have found the answer you gave me without being a serious tech person.

Thanks again.

Hi,

I've been using linux for 4 days now and i cant really figure out what ive been doing wrong, I have the exact same problem, but im using a realtek rtl-8169 wireless usb adapter and no wired connections. I have ubuntu 11.10 server edition so its only terminal and no internet.

I would really appreciate any help at all, I have the cd for drivers but no clue how to install..
