Description of problem: Upgrading from kernel 3.3.0 to 3.3.1 stopped my machine from detecting it's wireless network interface. Kernel 3.3.2 does not resolve this for me. Booting to 3.3.0-4.fc16.i686.PAE allows wifi device to still work. (However, the older kernel causes problems with my VirtualBox installation, and I really need both to work at the same time.) Version-Release number of selected component (if applicable): 3.3.1-5.fc16.i686.PAE 3.3.2-1.fc16.i686.PAE How reproducible: Always Steps to Reproduce: 1. sudo yum update to get kernel 3.3.1 or 3.3.2 2. reboot 3. network manager fails to detect wifi device ifconfig -a also fails to detect wifi device Actual results: System does not detect wifi device, so will not attempt to make a wifi connection. Expected results: Should detect wifi device and make a connection. Additional info: Similar to bug 810678 reported 08-April-2012. But the fix for that bug did not fix my problem.

Someone at fedoraforum.org suggested I reinstall kmod-wl. I did this and achieved a partial resolution (can post the yum trace if it would be helpful). Yum installed the non-PAE version of 3.3.2 kernel. Current status is: 1. If I boot to the non-PAE kernel, wireless works (and VirtualBox also works). [user@vos ~]$ uname -a Linux vos.somewhere.com 3.3.2-1.fc16.i686 #1 SMP Sat Apr 14 01:11:09 UTC 2012 i686 i686 i386 GNU/Linux 2. If I boot to the PAE kernel, wireless still does not work. My wireless device is not detected by network manager or by ifconfig -a. [user@vos ~]$ uname -a Linux vos.somewhere.com 3.3.2-1.fc16.i686.PAE #1 SMP Sat Apr 14 00:50:11 UTC 2012 i686 i686 i386 GNU/Linux
Severity/priority could be lowered, from my point of view, as I now have a workaround.
Problem resolved with: sudo yum install kmod-wl-PAE Apologies for raising a non-bug.
