 /*
  
- This example connects to an unencrypted Wifi network. 
+ 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.
+ 
  Circuit:
  * WiFi shield attached
