/* This example connects to a WEP-encrypted Wifi network. Then it prints the MAC address of the Wifi shield, the IP address obtained, and other network details. If you use 40-bit WEP, you need a key that is 10 characters long, and the characters must be hexadecimal (0-9 or A-F). e.g. for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work (too short) and ABBAISDEAF won't work (I and S are not hexadecimal characters). For 128-bit, you need a string that is 26 characters long. D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters, all in the 0-9, A-F range.
