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.

!!!Connect No Encryption

This example shows you how to connect to a WEP encrypted 802.11b/g network with the Arduino WiFi shield. Your Arduino's serial monitor will provide information about the connection once it has connected.

(:div class=BOM :)
!!!Hardware Required
* Arduino WiFi Shield
* Shield-compatible Arduino board
(:divend:)

!!!Circuit
(:div class=circuit :)

The WiFi shield uses pins 10, 11, 12, and 13 for the SPI connection to the HDG104 module. Digital pin 4 is used to control the slave select pin on the SD card.

You should have access to a 802.11b/g wireless network that connects to the internet for this example. You will need to change the network settings in the sketch to correspond to your particular networks SSID.

WEP network passwords are hexadecimal strings known as keys. A WEP network can have 4 different keys; each key is assigned a "Key Index" value. For WEP encrypted networks, you need the SSID, the key, and key number.
