Packages

• Fedora Packages(1): Fedora Core includes the ipw2100-drivers in FC3 (with updates) and FC4. You still need to grab the firmware from http://rpm.livna.org/
• Fedora Packages(2): http://www.atrpms.net/name/ipw2100/
• Mandriva Packages: modules included in stock kernel packages; firmware included in commercial distribution or available from http://plf.zarb.org/.
• Debian Packages: http://packages.debian.org/ipw2100-source or inclueded in the kernel package (since 2.6.14 (?))

Status

• In development but usable. Version 1.0.5 works quite well with kernel 2.6.10.
• Works very well with kernel 2.6.16-9. Only firmware needs to be copied to the appropriate directory and everything works out-of-box.

Additional Comments

Make sure to try the newest version. You will need to install the loadable binary firmware provided on http://ipw2100.sourceforge.net/firmware.php as required by the driver.

To install the firmware, decompress the .tgz in /lib/firmware

To turn off the radio on boot-up load ipw2100 with option disable=1, i.e. # modprobe ipw2100 disable=1.
