Broadcomm 43xx on Karmic Koala

Thanks to Karmic which has made me come back and wrote somethings down here.
I found my first case, there was a netbook which run smoothly on JJ. But when i installed KK on it, the wireless did not do anything....hmmm

so....here we go:

1. Open terminal, make sure that your wireless is "Broadcomm 43xx" by typing sudo lspci
2. Insert Ubuntu 9.10 LiveCD to CD-ROM drive.
3. Type these command below

sudo apt-cdrom add
sudo apt-get install dkms patch fakeroot bcmwl-kernel-source

4. Restart computer.
5. Go to System - Administration - Hardware Drivers; Broadcomm BCM43xx wireless chip had been detected
6. Now it's time to set the wireless connection
