The wireless card as identified by lspci:
Network controller : Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)
I'm new to Ubuntu and I've found this guide which addresses my issue exactly. I've got internet connectivity and I just want to enable the wireless card on this old Dell laptop. However, I'm running Ubuntu Server 10.10 and I would rather not install a Desktop. Thus, I'm stuck at the following step:
Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.
Is it possible to accomplish this in the CLI?
