I recently installed Ubuntu linux on my Gateway PC, but the PC can pick up the wireless card but not show any access points. I ran "Hardware Testing" and learned that the card is a "Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)" I have tried to use ndiswrapper but I struck no gold. If someone can tell me how to use Ndiswrapper or a good alternative, The help would be greatly appreciated. (The computer has internet access now, but I don't want to carry the tower up 2 flights of stairs every time I want to download somthing xD.

Thanks in advance,

EDIT: BTW I am running 8.10 Hardy Heron.
