[Question #78116]: Broadcom BCM4318: Wireless scan shows no result

Hello!

I am using Kubuntu 9.04 Jaunty Jackalope with the KDE 3.5.10 Remix. I was using Hardy Heron previously, and the wireless was working. Since the system update, I can't find any more wireless networks. The blue light on the wireless button on my Compaq nx6110 notebook however indicates that the wireless hardware is working.
I first thought it is a problem related to NetworkManager. Now I deleted that programme and installed wicd. Ethernet works fine, but wicd shows no wireless networks in the environment even though it should. The same goes for this:

wolfgang@nb-wolfgang:~$ iwlist wlan0 scan
wlan0     No scan results

Some more system output to give you an idea of my system:
wolfgang@nb-wolfgang:~$ lspci -v
[...]

I also tried to do something about the driver. I followed the tutorial on http://linuxwireless.org/en/users/Drivers/b43 and did the following:

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-012.tar.bz2
tar xjf b43-fwcutter-012.tar.bz2
cd b43-fwcutter-012
make
cd ..
export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
tar xjf broadcom-wl-4.150.10.5.tar.bz2
cd broadcom-wl-4.150.10.5/driver
sudo ../../b43-fwcutter-012/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta_mimo.o

and then I rebooted. To no avail.

Does anyone have a clue how to fix the problem?
