As Jchung said, MA701 works out of the box, I myself use this card.
Setup is pretty straightforward. Go to 'Settings' tab and tap on 'Network' icon. Tap on 'New' button, select 'Wireless LAN' from the list and tap 'Add' button, then enter SSID and WEP information in the respective fields. After you are done you will see a 'globe' icon in the task bar. Tap on the globe, select the account you just created and tap connect.
