I don't think I ever tried WiFi with 6.06; I did have it working with
6.10, using the config files below. With 7.04 (Feisty) beta, it works
like a charm, without config files - I let Network Manager do the work,
and all is well, and I'm using WPA2 (RSN) with AES on that network.

For 6.10, my config files were the following:

% cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp
wireless-essid mySSID # I don't this was necessary
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

% cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=dialout
network={
        ssid="mySSID"
        key_mgmt=WPA-PSK
        proto=WPA
        pairwise=TKIP
        group=TKIP

psk=0f4a8f36f162d60701b4730fb484a40dce1cd85464de0ceb02d32f4b7b351903

}

The psk was generated using

% wpa_passphrase mySSID "my very secret passphrase"

You don't have to do this, you can put the passphrase in the
wpa_supplicant.conf, just quote it:

	psk="my very secret passphrase"

wpa_supplicant will then generate the passphrase itself. The on-line
pages do say this is a performance hit, though, and generating the key
yourself is quite easy.

This - quoted or not, passphrase or actual key - was the biggest
stumbling block I had to getting WPA working under 6.10: I had to ensure
that I used the right datum on the client and the AP. In the end, the AP
wanted the passphrase, unquoted, but called it the key, while
wpa_supplicant can play either way, you just need to know which datum
gets the quotes....
