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.
