Encryption

Encryption technology is used to enhance wireless media security. Your encryption set-

tings must match those used by the Access Points or wireless stations (ad hoc mode) in

your network, or your computer will be unable to communicate with others through the

network.

If you are not going to use encryption, go to the Encryption tab and select Disabled

from the Encryption drop-down menu. However, if you want to enable encryption,

please do the following:
1. Select the Encryption tab from the Wireless LAN Monitor Utility.
2. Select 64 Bit or 128 Bit as your encryption type.

For flexibility, you can enter the WEP keys in either HEX or ASCII format. Enable the

preferred format and then enter the key values in the Key #1- Key #4 fields.

If using HEX format, the utility converts two entered characters into their corre-

sponding ASCII code and vice versa. Note that when using HEX format, only digits

0-9 and letters A-F are allowed. The valid key length for each encryption type is as

below:

Note that the four keys, including the one selected as WEP Key to use, are used to

decrypt the data you receive.

3. In the WEP Key to use box, select one of the four keys to encrypt the data you are

going to transmit.

4. Select the Authentication Type.

Your authentication type must be the same as those on the Access Point/wireless

network adapter (ad hoc mode) with which you want to associate.

i

If you want to use encryption in infrastructure mode, please proceed as

follows:

Ensure that encryption is activated on the Access Point.

Convert your passphrase for the Access Point to HEX format and type

the key values into the appropriate fields Key #1- Key #4.

Using the HEX format makes sure that the keys are the same, even if wire-

less devices use different procedures to convert passphrases.
