Intel has been releasing open source drivers for its PRO/Wireless 2100 products for several months now, which can be found in Centrino-based laptops. These drivers only work on Linux with kernel version 2.4.23 and 2.6.1 or higher, and require Wireless Tools for Linux and the IPW2100 firmware image to do their job. The release notes announce the following changes:

  • Wrapped a few printk()’s in IPW2100_DEBUG macros so that they are not filling the logs if you don’t want to see them (bug 139)

  • If you use Monitor mode, make sure you take down the interface first:
    % ifconfig eth1 down
    % iwconfig eth1 mode monitor
    % iwconfig eth1 up
    Users have reported that failure do to so frequently does strange things with the keyboard.
