The first step is to gather more information.
Run "sudo /sbin/lspci -v" and post the section about your wireless device.
Then run "sudo /sbin/lspci -n" and post the results.
Post the results of "uname -r" so we know which kernel version you have.
Most broadcom devices use either the b43 or b43-legacy kernel modules. This kernel module used to be called bcm43 in older kernels. Sometimes if a device is new, you need a newer kernel so that it is detected.
For broadcom wireless devices, you need the b43-fwcutter package to cut out and copy the firmware from a driver written for windows (bcm43-fwcutter on older kernels IIRC).
If you need the b43 firmware, this script may help. It is from SuSE Linux, but I used it for Fedora 11 successfully. At least the url's & README reference should be useful. I added the .txt extension so I could upload it. You might want to rename the file, and make it executable. It needs to be run as root.
