thanks, i downloaded the b43.zip firmware from above page, and the instructions to install is this:
(start) Now, download all the files, and put them into a folder and give a name like "B43", then take the folder to your desktop.
Now open the terminal and type this commands:
sudo mkdir /lib/firmware/b43
sudo cp -/Desktop/b43/* /lib/firmware/b43
sudo modprobe b43
If your wireless doesn't start immediately then reboot your system. (end)
when i got to the secong line, this:
sudo cp -Desktop/b43/* /lib/firmware/b43
cp: invalid option -- '/'
what do i change that line too?
