[elrepo] kmod-compat-wireless - and BCM4313 [14e4:4727]

[ni at centergate.net]

Hi,

I recently installed Centos 6.3 Minimal on my Dell Latitude Laptop
(E6520), prior to that I had Ubuntu 10.10. I've been having one heck of
a time getting my wireless to work properly.

Current setup:

Wireless card: 03:00.0 Network controller [0280]: Broadcom Corporation
BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

Kernel: 2.6.32-279.2.1.el6.x86_64

Software:  kmod-compat-wireless-3.3-2.n.el6.elrepo.x86_64.rpm

lo        no wireless extensions.
em1       no wireless extensions.
vmnet1    no wireless extensions.
vmnet8    no wireless extensions

lsmod  | grep "b43\|ssb\|bcma\|wl\|brcm"
bcma                   25498  0


lspci -vnn

03:00.0 Network controller [0280]: Broadcom Corporation BCM4313
802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
	Subsystem: Dell Inspiron M5010 / XPS 8300 [1028:0010]
	Flags: bus master, fast devsel, latency 0, IRQ 17
	Memory at e4b00000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [40] Power Management version 3
	Capabilities: [58] Vendor Specific Information <?>
	Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [d0] Express Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [13c] Virtual Channel <?>
	Capabilities: [160] Device Serial Number 00-00-c4-ff-ff-f4-68-a3
	Capabilities: [16c] Power Budgeting <?>
	Kernel driver in use: bcma-pci-bridge
	Kernel modules: bcma

So I feel like with the above I'm part way there, though I could be
terrible mistaken.

I located the following thread which I thought would be my saviour:

http://grokbase.com/t/centos/centos/125s7snzw1/support-for-broadcom-bcm4313

But it errors out:

modprobe brcmsmac

FATAL: Error inserting brcmsmac

I was wondering if someone could shed any insight on if I'm doing
something wrong, if I'm using the incorrect software combination or
there's a bug in the code (http://elrepo.org/bugs/view.php?id=285).


Appreciate any insight or direction.

Thanks!
