WLAN(WiFi) of Ubuntu 8.04 on DELL D420, Kernel 2.6.24-19
After Ubuntu 8.04 updating to Kernel 2.6.24-19-generic, my wireless card is lost and WLAN configuration is invalid.
It spent my 4 hours to solve this problem, the following is summary:
1. Install b43-fwcutter,
sudo apt-get install b43-fwcutter
2. Run b43-fwcutter
sudo /usr/share/b43-fwcutter/install_bcm43xx_firmware.sh
3.rmmod
rmmod ndiswrapper
rmmod ssb
rmmod b43
4.modprobe
modprobe ndiswrapper
modprobe ssb
modprobe b43
5. To check wlan0, OK
ifconfig -a
6. Config WLAN
Ubuntu Status bar, left click “Network”, Mannual configuration, unlock, Wireless connection, Properties, WPA, DHCP or IP (depend on your AP), disable LAN, save as a new network location.
Before these steps,
I have updated ndiswrapper to V1.9, both common and util, and found no ndiswrapper in /usr/sbin, so make a link(ln -s).
Reinstall DELL Wireless bcmw15.inf

It works, so I post this article by WLAN.
