I have a Broadcom 802.11b/g hardware on my dual-boot laptop. Note first that in the WinXP partition, the wifi makes DHCP connections to my router with no problem. Since this was not working in my new CentOS 6 partition, and remembering that there was a driver problem with the old Fedora partition it replaced, I followed instructions founs at: http://repecka.net/en/2011/04/19/install-broadcom-bcm4311-802-11bg-wlan- drivers-on-centos/ and http://www.broadcom.com/docs/linux_sta/README.txt modifying for that fact that I use wlan0 rather than eth1. The wifi is now dead-in-the-water. The wlan light now remains red, and neither ifconfig nor iwconfig show any sign of wlan0 (contra to the situation before I installed the new driver). It still works in the WinXP partition. Suggestions for my next step in fixing this would be most welcome. Thank, Mike.

[...] I note that instructions indicated that I should modify /etc/modprobe.conf to contain: alias eth1 wl Since I don't have that file, I grepped around and decided that the file to use is probably: /etc/modprobe.d/dist.conf So in that file I put: alias wlan0 With regard to the library, I tried several things, the latest being: alias iee80211_crypt_tkip lib80211 Might there be a problem herein? Thanks, Mike.
I didn't read the whole thread but you should make sure you blacklist the
b43, bcm43xx and ssb drivers
vi /etc/modprobe.d/broadcom-wl.conf
blacklist b43
blacklist bcm43xx
blacklist ssb
and also add intel_iommu=off to the kernel line in your grub configuration.
That works for my broadcom adapter
