kernel update caused wireless problem?

Hello

yesterday I updated the kernel to 2.6.43.2-6.fc15.i686.PAE. Since then I cannot list / see / connect to any wireless network. It seems they have disappeared.

Some details that might help:

$ lspci | grep Wireless
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

when I try to start the NetworkManager I get (from swatch that monitors the log files):

$ NetworkManager

Is this a bug from the new kernel? Should I wait for the next kernel release? Or am I missing something?

Anyone has an idea that could help me out?

thanx
