The wireless lan card in the iConnect is de Ralink RT3090 PCIe half card
This one avalaibe in the kernel sinds 2.6.38+. In Downloads section the driver is already static compiled into the kernel
You'll need some extra firmware to get it working
wget http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-ralink_0.35_all.deb dpkg -i firmware-ralink_0.35_all.deb
Now you shoud have an interface wlan0. To add wpa2 security I suggest to add the wpasupplicant package
apt-get install wpasupplicant
Modify your interfaces file (nano /etc/network/interfaces) and add wifi config, for example:
#Wi-fi auto wlan0 iface wlan0 inet dhcp wpa-ssid myssid wpa-psk mypassword wpa-key-mgmt WPA-PSK wpa-group TKIP wpa-pairwise TKIP wpa-proto WPA
Reboot and enjoy your wifi!!
