ipw2100 wireless adapter and Linux

Tuesday, June 26th, 2007

After reinstalling Linux on a IBM Thinkpad X31 i forgot that the wireless adapter was not just plug-and-play. Linux detected the adapter, but because of license issues the firmware is not bundled with the kernel:

ipw2100: eth2: Firmware 'ipw2100-1.3.fw' not available or load failed.
ipw2100: eth2: ipw2100_get_firmware failed: -2
ipw2100: eth2: Failed to power on the adapter.
ipw2100: eth2: Failed to start the firmware.
ipw2100Error calling register_netdev.

The firmware must be downloaded from http://ipw2100.sourceforge.net/firmware.php and the extracted files must be put in /lib/firmware.

After rmmod ipw2100 && modprobe ipw2100 the adapter works again…
