broadcom-wl help

I was given an ancient MacBook (Core2Duo) and I've got the LXQT spin running on it but it has a BCM4321 wireless chip in it. I have the broadcom-wl package installed and the kernel module was built successfully and is loaded (wl module) but I still can't use the wireless adapter. ifconfig doesn't show it's even present. Troubleshooting tips? Thanks, Richard
