Setting up wifi on a Debian IRLP node is fairly easy to do.

First, you will want to install wireless-tools and the wpasupplicant

COMMAND:
apt-get install wireless-tools wpasupplicant

Then have a look at

You need to manually edit your /etc/network/interfaces file to do it, and that
is the hardest part.

Some good info about systems that require boot-time firmware is available at:
