I am new to Ubuntu, just installed it for the first time on my Dell Latitude D630.
My wireless card does not work, it doesnt show any wireless networks in range.
I believe the card is a broadcom sta. i activated the addtional driver needed, and it says :

This package contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-,BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-basedhardware.

Can somebody please help me get my wireless card to work?
My professor (im in computer science) made us install Ubuntu, and Im a noob to linux.
