Okay, this is a tutorial for something I have had a hard time with, solved, and want to share the solution for everyone; how to install wifi firmware(drivers) on a Dell Latitude D600 (that has no internet connection otherwise) for use with Ubuntu 10.10 Desktop Edition.

What you will need:
  • Another Internet Capable Computer (For downloading Drivers)
  • A USB Flash Drive with at least 2MB free space
  • A Dell D600 Laptop (Normally has broadcom wifi, for other wifi cards this will not work)

Lets get started:
  1. Using your internet capable computer Download these packages to your flash drive:
  2. Plug your flash drive into the D600 and copy the above files into your home folder.
  3. Open b43-fwcutter_011-1_i386.deb By right clicking and selecting 'Open with Archive Manager'
  4. Extract b43-fwcutter from the /usr/bin folder of the b43-fwcutter_011-1_i386.deb archive into your home folder.
  5. Now open a terminal and type these commands one by one:
    sudo ~/b43-fwcutter -w /lib/firmware wl_apsta-
    tar xfvj ~/broadcom-wl-
    sudo ~/b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-
    sudo chmod o+rx /lib/firmware/b43 /lib/firmware/b43legacy
  6. That's It!!! Check your networks, your wifi card is already running, you may now delete the files from your home folder!
