Raspberry Pi Model B, Home Wi Fi config on AirPort (Time Capsule)

So I have an all-Apple household.  My wi-fi router is an old Time Capsule.

To get wi-fi working on my box, I simply edit: /etc/network/interfaces and put this code in

1. auto lo
2. iface lo inet loopback
3. iface eth0 inet dhcp
4. allow-hotplug wlan0
5. auto wlan0
6. 
   
7. iface wlan0 inet dhcp
8. wpa-ssid "myssid"
9. wpa-psk "mywpapassword"

Pretty simple. Works like a charm on my network.
