Worked great after I emerged net-wireless/madwifi-driver. I didn't even need to rebuild the kernel (though I do need to re-emerge for each kernel, after changing the /usr/src/linux symlink). I had to set the mode=2 (`/usr/sbin/iwpriv ath0 mode 2`) in the init scripts, otherwise it wasn't scanning.

I've only had it for about a week, but no hitches so far. The lights tend to blink unceasingly, which is kinda annoying, but nothing a piece of tape won't fix :)

For the curious, here's the output of `iwpriv ath0`:

Got mine today and it ran out of the box...good buy.

Same as ubermenschx

Nice card, very sensitive.
The installation was even easier in ubuntu than in windows XP .
Real plug and play.
