My HP G62 laptop has a BCM 4313 rev 01 PCI wireless adapter. When I first
installed Ubuntu in the summer of 2010, I had to use Ethernet to my router to
install the Wireless driver.

This fall I have done clean installs of Ubuntu, Kubuntu, Mint and Puppy without
ever using an Ethernet cable. Just have to enter the WPA key, and Bob's Your
Uncle. (I installed the last two on flash drives, yes real installs.)
