Check your BIOS for anything related.


Have you examined your dmesg, /var/log/messages carefully ?

These are the devs of b43 firmware.
$ yum info b43-openfwwf
If you need help, send a message to the OpenFWWF team at 
 openfwwf at
To make firmware work properly:
$ cat /etc/modprobe.d/openfwwf.conf 
options b43 nohwcrypt=1 qos=0

You can retry:
# modprobe -r b43
# modprobe b43 nohwcrypt=1 qos=0

and check /var/log/messages.

# modinfo b43
# lsmod |grep -i b43

Btw, please do not top post (on top of previous text) - most people prefer
bottom posting, otherwise some can get angry and refuse helping you :-)
