The two drivers each use different firmware. So depending on where you got your firmware, only one version of the driver should work at all. Also, there is some hardware that works better (or only works) with one version of the driver or the other. Including both versions for now seems like the better choice. Are you observing an actual problem from both drivers being loaded? Or is the WPA2 connection failure the real problem? Please try the test kernels here: http://people.redhat.com/linville/kernels/fc7/ Do they work any better for WPA2? Closing on the basis of the "subject" problem having been addressed. |
Description of problem: The new development kernel for fc7 changed its wireless support driver for bcm43xx based cards from the (SoftMAC based) "bcm43xx" to the (mac80211 based) "bcm43xx_mac80211". However, the old SoftMAC based bcm43xx driver still gets loaded by the kernel, in addition to the new one.
