Looks like I'm in the same boat. I got some time, removed everything I
could so I could start with a clean slate.


Downloaded and installed the following:

96cf06e4ff9f0c04a0f26ebefdf32e3d  /lib/firmware/brcm/bcm43xx-0.fw
48882412db63b4e2dd9c26571a29a799  /lib/firmware/brcm/bcm43xx_hdr-0.fw


Next I installed kmod-compat-wireless-3.5-3.el6.elrepo.x86_64.rpm


Did the following commands:

depmod -a
modprobe brcmsmac


lspci -vnn shows:

So here is the issue, similar to Roy's

kernel: ieee80211 phy0: brcmsmac: fail to load firmware brcm/bcm43xx-0.fw
kernel: ieee80211 phy0: brcmsmac: Failed to find firmware usually in
/lib/firmware/brcm
kernel: brcmsmac: brcms_bcma_probe: brcms_attach failed!


If there are other things I can do or test, let me know.

Thanks Phil!

Cheers,
