Public bug reported:
Hello, i tri'ed to connect my notebook with Ubuntu Jaunty to wifi access
point, but failed to do it.
I have Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
I think, to provide more relevant information, i'll beter write here all
my actions to debug it.(without unrelevant, like googl'ing, of course :)
)

eth0 Interface doesn't support scanning.

pan0 Interface doesn't support scanning.
After searching information for "Failed to read scan data : Invalid argument",
i've found that this happen's with many of people using "wl" module
# lsmod | grep wl
wl 1489748 0
ieee80211_crypt 13444 2 ieee80211_crypt_tkip,wl
dmesg didn't showed me any more information:

so i decide to try b43 module.
I installed b43-fwcutter, and it fetch'ed and extracted broadcom firmware while
were installed.
# du -hs /lib/firmware/b43

i unloaded wl:

Now i get wlan0 interface:
# iwconfig

eth0 no wireless extensions.
pan0 no wireless extensions.
wmaster0 no wireless extensions.

lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.

wmaster0 Interface doesn't support scanning.
wlan0 No scan results
There were no more messages in dmesg after this action
Network manager too doesn't see network, but it is 100% availible and
accessible from this notebook loaded with Windows LiveCD
As i understand, this is becouse of:
[ 1278.120091] b43-phy0: The hardware RF-kill button still turns the radio
physically off. Press the button to turn it on.
But pressing Fn+F5 seem's change nothing. And this is only way to
enable/disable wifi on my notebool, there is no other button or switch.
Also i can't change rf switch in bios to be always on, just becouse
there is no such option in it :(
The only relevant information about this i found here:
http://linuxwireless.org/en/users/Drivers/b43/faq
Q: The radio-enable-button on my laptop does not work.
A: You have to enable RF-kill support in the kernel configuration. The config
options you have to enable are: CONFIG_RFKILL, CONFIG_RFKILL_INPUT,
CONFIG_INPUT_POLLDEV.
But i doesn't have enough knowledge about kernel in ubuntu(and just
kernel building) to compile it properly myself with setting this options
So, i doesn't have any way to make wifi work properly.
Some information about my system:

Sorry, if this bug is not related to kernel, but i really don't know
where to report it. It doesn't seem's as bug of 'b43' module, becouse
'wl' doesn't work too(but i'm not sure that this is becouse same reason)
Thanks for your time.
Konstantin Klimentov.
P.S.
dmesg.log in attachments is full log after rebooting system and performing:
# iwconfig; iwlist scan; rmmod wl; modprobe b43; iwconfig; iwlist scan; dmesg >
dmesg.log
full_cmd_after_reboot.log is output of this commands.
