The laptop contains a Intel PRO/Wireless 2200BG 802.11b/g mini-pci adaptor card. It's supported by the ipw2200 driver, which Fedora includes. The driver needs to download some firmware to the card during initialization. Unfortunately, Fedora does not include that firmware. You need to download them from http://ipw2200.sourceforge.net/firmware.php,
and unpack the tar file into /lib/firmware.
There are multiple versions of the firmware, and you need the right version for the driver in your kernel. Fedora core 4 ships with version 1.0.0 of the driver, which needs the 2.2 version of the firmware. The 2.3 or newer firmware will NOT work.
Once you have the firmware installed in /lib/firmware, unload and reload the ipw2200 module. using the commands;
command should list the adapter as eth1, and it's status.
You may need to create a file /etc/sysconfig/network-scripts/ifcfg-eth1, containing:
Once that file exists, /sbin/ifup eth1, should bring up wireless networking.
Now this worked perfectly for me. I believe it will work for you if you follow the instructions. I got this information from http://copland.udel.edu/~doke/dell_d810/
