[ubuntu] Broadcom Wireless Setup for Hardy (Step by step)

[alex_kent_18]

I used the following steps to enable my Broadcom Wireless BCM4312 (rev 02).

Step 1 (run in terminal)

echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
sudo apt-get install ndiswrapper-utils-1.9
mkdir ~/bcm43xx; cd ~/bcm43xx

For Step 2, You can check your Broadcom wireless version with this command in terminal : "lspci | grep Broadcom\ Corporation",if your wireless device is different from BCM4312 (rev 02), please refer to the following link for this step and you can continue again with step 3 onwards:
