Slackware :: Getting The 13.1 BCM4312 Wireless Setup?

I'm on a Dell Latitude E6500, and I'm switching from Windows 7 to Slackware 13.1; I've never used linux before. I'm trying to set up wireless internet, and it doesn't seem like there's any standard way of doing it for my system. When I run the "lspci -v" command, I find this:

Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb

When I run the "lsmod" command, This comes up:

Module Size Used by

b43 162121 0

And the wireless doesn't work.
