Wireless (offline install)
Note: Requires access to a Debian workstation with internet connection & two USB sticks.
On another Debian machine, run:
- sudo apt-get install firmware-b43-installer
Copy the contents of /lib/firmware/b43 to another USB stick
Run the Debian installer in text mode. When you get to the stage "detecting network hardware", swtich to the second tty (fn+alt+f2), press enter to activate, and run:
- mkdir /lib/firmware/b43
Mount the second USB stick
- mount /dev/sdc1 /mnt
Copy the firmware to the ramdisk's filesystem
- cp -a /mnt/. /lib/firmware/b43
Switch back to the installer with (fn+alt+f1)
Your wireless should now be functional.
