[CentOS] Broadcom Wifi Problem

[James A. Peltier]

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

| 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.
