Wireless Adapter not functioning - New RHEL 6.4 Desktop on Dell E6530

Hi, I'm having a little trouble getting my wireless NIC working with RHEL 6.4.  lspci shows that the NIC is installed, but I don't see a wireless adapter in ifconfig -a.

03:00.0 Network controller: Broadcom Corporation BCM43228 802.11a/b/g/n

There are a lot of solutions on the web and I just replaced Ubuntu which was working fine.  What is the proper way to troubleshoot and resolve this?

Thanks.
