ndiswrapper is a really nifty application and Linux kernel module that will let you use just about any network card supported by Windows. Here are some notes for enabling various wireless cards (both PCMCIA and PCI). The tips are quite specific to Ubuntu so you may want to look elsewhere if you aren't running that.
Handy commands to use
This will show what wireless networks are visible to your wlan0 card
iwlist wlan0 scan
This will show the wireless capability of each visible network interface
This will show what drivers and hardware is visible to ndiswrapper
ndiswrapper -l Installed ndis drivers: 2802w driver present, hardware present 2802wo invalid driver!
To ensure the kernel module gets loaded at boot ...
echo "ndiswrapper" >> /etc/modules
This method applies to Ubuntu, other distributions might use an entry in modules.conf To blacklist a module, add it to /etc/modprobe.d/blacklist
To see pci device information - useful for identifying what wireless devices you have
Same, but show the pciid listed on the ndiswrapper index.
D-Link AWG-510 PCI wireless / Ubuntu / Dell Optiplex GX200
The card appears like this in the lspci output. Though not obvious, the model corresponds to a WL-138g on the ndiswrapper list.

Great instructions can be found at http://www.ubuntuforums.org/archive/index.php/t-76804.html Resulting device was wlan0 - not eth1 as I had expected.

Note that is device is rebranded as a Dell Truemobile 1450 MiniPCI.
Found driver from ndiswrapper driver page referenced above
unzip from /tmp/tmp2 (warning: the .exe doesn't have friendly subfolder structure)
ndiswrapper -i AR/bcmwl5a.inf Installing bcmwl5a Forcing parameter IBSSGMode|0 to IBSSGMode|2
ndiswrapper -l Installed ndis drivers: bcmwl5a driver present, hardware present
The rest follows as above, modprobe ndiswrapper and so on. After running modprobe ndiswrapper, dmesg shows:
[5079478.159000] ndiswrapper version 1.1 loaded (preempt=no,smp=no) [5079478.245000] ndiswrapper: driver bcmwl5a (Broadcom,04/09/2004, 18.104.22.168) loaded [5079478.246000] ACPI: PCI Interrupt 0000:02:03.0[A] -> Link [LNKB] -> GSI 7 (level, low) -> IRQ 7 [5079478.254000] ndiswrapper: using irq 7 [5079478.915000] wlan0: ndiswrapper ethernet device 00:90:96:c6:41:87 using driver bcmwl5a, configuration file 14E4:4324.5.conf [5079478.916000] wlan0: encryption modes supported: WEP, WPA with TKIP, WPA with AES/CCMP
Next step... enable WPA with TKIP !
Ok so I finally get back around to enabling WPA, using the instructions found here, and what would you know but the output from dmesg has changed!
jetson:/var/log> dmesg | egrep 'ndis|wlan' [4294690.470000] ndiswrapper version 1.1 loaded (preempt=no,smp=no) [4294690.515000] ndiswrapper: driver bcmwl5a (Broadcom,04/09/2004, 22.214.171.124) loaded [4294690.521000] ndiswrapper: using irq 7 [4294691.023000] wlan0: ndiswrapper ethernet device 00:90:96:c6:41:87 using driver bcmwl5a, configuration file 14E4:4324.5.conf [4294691.023000] wlan0: encryption modes supported: WEP
Somehow I lost WPA support along the way. Mystery unfolds.
Update 2006-12-11... So after upgrading to 6.06 LTS (Dapper) I now have a different version of ndiswrapper installed now (as per dmesg)...
ndiswrapper version 1.8 loaded (preempt=yes,smp=no)
Also wlan0 has dissappeared to be replaced by eth1, which appears as this in the output of iwconfig.
eth1 IEEE 802.11b/g ESSID:off/any Nickname:"Broadcom 4306" Mode:Managed Access Point: Invalid Bit Rate=1 Mb/s RTS thr:off Fragment thr:off Encryption key:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Hrm, this it not a 4306 but a 4309.
