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...

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.
