Using a Hexadecimal Key
A hexadecimal key is a mixture of numbers and letters from A–F and
0–9. 64-bit keys are 10 digits long and can be divided into five two-
digit numbers. 128-bit keys are 26 digits long and can be divided into
13 two-digit numbers.
For instance:
AF 0F 4B C3 D4 = 64-bit key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit key
In the boxes below, make up your key by writing in two characters
between A–F and 0–9. You will use this key to program the encryption
settings on your Router and your wireless computers.
Note to Mac users: Original Apple AirPort products support 64-
bit encryption only. Apple AirPort 2 products can support 64-bit or
128-bit encryption. Please check your product to see which version
you are using. If you cannot configure your network with 128-bit
encryption, try 64-bit encryption.
