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 ----- Original Message ----- | 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. | | _______________________________________________ | CentOS mailing list | CentOS at centos.org | http://lists.centos.org/mailman/listinfo/centos -- James A.
