Wireless b43 driver - loads itself ok, interface present, but no networks detected

[evad]

I have a task to install Fedora 8 on Dell Latitude D400 laptop with Dell Wireless / Broadcom wireless adapter. I have managed to install firmware using b43-fwcutter, driver loads itself properly, I've also added alias wlan0 b43 to /etc/modprobe.conf, and there is wlan0 interface. Everything looks great so far, but... wireless adapter doesn't detect any networks at all! :( iwlist wlan0 scan returns 'No scan results'. NetworkManager, or wifi-radar obviously can't see any wireless networks either.

I've tried to google around, but haven't found any solution yet. I'd like to avoid to use ndiswrapper, as b43 driver seems to load properly, there must be some tiny catch that adapter doesn't see networks...

I'd be greatly appreciated for any help on that matter. Here are some useful outputs:

dmesg | grep b43

Check to see if the older bcm43xx module is loaded. ' /sbin/lsmod '

Nope, there is no bcm43xx module... :(

Hello probably a silly question but is the aerial turned on (switch on side of laptop)

This laptop doesn't have side switch - only soft key combination, which I've also tried already...

UPDATE: Wireless works! And the reason was... turned off wireless adapter by Fn-F2 softkey combination! When I tried that before, I probably didn't wait enough for adapter to get up, and killed it by pressing Fn-F2 again...

I am now completely red on my face now, and feel like a fool... :| However, thank you very very much for that suggestion. I would probably never tried that solution later.

probably just one of many broadcomm chipsets that will not work with either bcm43xx or b43-fwcutter. ndiswrapper looks to be the only choice. It has worked very well for me with the many I have setup. I still perfer Atheros based chipsets though and some prism ones.
