Default Fwd: centos Wireless - Broadcom BCM4313

Dear All,

I'm trying to configure wireless card on a Dell Vostro 1540.

I had a look at this site : http://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom?action=show

wireless card :# /sbin/lspci | grep Broadcom
12:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

I decided to follow the ELrepo instructions suggested on the site :

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

because it would give me a clear and present rpm that I can use on different machines and that will survive kernel updates.

This all goes down without error messages.

After installing, there is a new entry in /etc/udev/rules.d/70-persistent-net.rules :

# PCI device 0x14e4:0x4727 (wl)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="94:39:e5:dc:3a:cf", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

and there is now a blacklist-Broadcom.conf in /etc/modprobe.d/:

blacklist b43
blacklist b43legacy
blacklist bcm43xx
blacklist ssb

So I think the driver works and the blacklist - issue that is reported on different sites is ok.

I then made an entry in /etc/sysconfig/network-scripts:

vi ifcfg-eth1

DEVICE="eth1"
#BOOTPROTO="dhcp"
HWADDR="94:39:e5:dc:3a:cf"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE=Wireless

*The problem is* I'm not seeing any wireless networks.

Eth1 seems to try to get an adress via dhcp and then exits.

And it is listed in the gui as wired network...

[root@wduerloo ~]# dmesg | tail -n15

on restarting network manager this is in /var/log/messages :

I think I need to configure something else.

I know a lot of you guys don't like NetworkManager but because it's a laptop I would like to use it.

I hope I gave enough info, any help would be greatly appreciated.

greetings, James.

Centos is here to stay, I'm sure.

P.S. I don't have an English spell checker on this machine, sorry for language mistakes :=)
