the wireless lan card card in my laptop wont work

I have installed kubuntu 11.04 on my HP zd8004 laptop and cant get the wireless NIC working, I have read through several threads on various forums (the most closely related being https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/136097) I have taken the actions detailed in this problem - (see below) but had no sucess fixing the problem.

sudo apt-get update
sudo apt-get install b43-fwcutter

The commands and output specified in this thread are pasted below;

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|usb|witch|wl'; iwconfig; cat /etc/modprobe.d/* | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|witch|wl'; sudo hwinfo --netcard ; cat /var/lib/NetworkManager/NetworkManager.state; sudo lsmod

I tried to follow the link mentioned in the following output;
[ 206.052791] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found
[ 206.052799] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found
[ 206.052805] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.
 - but the URL points to a broken link and I have not been able to track the target data.

I have also tried installing a D-link pcmcia adapter - while I did get this connected once I had problems with it and would prefer to use the onboard card if possible for simplicity as well as power reasons. This machine worked well on wireless under windows so I am fairly confident the onboard card is working OK.

Your assistance is greatly appreciated, with thanks,

Bill

After several hours of searching I found an answer that worked for me - the solution (as documented at http://wiki.debian.org/bcm43xx) was to install the firmware using the "firmware-b43-installer", I was not aware the driver (which was automaticaly, and correctly installed at build time), required this additional, manual process.

The amount of support information available and the variation in its technical content and presentation as well as the breadth of systems covered is going to take some getting used to.

Please change the state of this question to solved, thanks.
