CentOS 6.5 Broadcom Corporation BCM43228 driver

I used these instructions to build a rpm for my wireless driver on my HP ProBook 650:

http://elrepo.org/tiki/wl-kmod

But, after it installs and I do the final step "modprobe wl" I cannot see the card with iwconfig or in NetworkManager.

What could be the issue here?

The difficulty is posting the step in the instructions does not reflect what you have which is often where a typo could be the culprit.

You might want to consider using DKMS so that whenever you update that alters the kernel version, this module will automatically is rebuilt/integrated on boot of the new kernel.

look at dmesg to see whether it reports an issue when loading/processing the boot up.

Why you build yourself?
Install this one: http://elrepo.org/tiki/kmod-compat-wireless if you really have broadcom card

HP says there aremultiple networking kits for that laptop:
Atheros 802.11b/g/n (1x1)
Combinación de Broadcom 802.11a/b/g/n (2x2) y Bluetooth 4.0
Combinación de Intel Centrino Advanced-N 6235 802.11a/b/g/n y Bluetooth 4.0
