Brodcom 43 Failing of FC8

I installed FC8 on my dual boot laptop, and ran "yum update".
when I try to activate Broadcom 43 my wifi, I get:


   SIOCSIFFLAGS: No such file or directory

   Determining IP information for wlan0...SIOCSIFFLAGS: No
   such file or directory
   SIOCSIFFLAGS: No such file or directory

Note lspci:
...
02:00.0 Network controller: Broadcom Corporation Dell Wireless 1390 WLAN 
Mini-PCI Card (rev 01)
...

Any suggestions?

Thanks,
Mike.
