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.
HEX Format ASCII Format
64 Bit 10 hexadecimal digits 5 ASCII characters
128 Bit 26 hexadecimal digits 13 ASCII characters
Open System The Access Point does not do the authentication.
Shared Key
The Access Point uses the WEP key for the Gigaset USB Adapter
11’s authentication.
Auto
Gigaset USB Adapter 11 detects automatically the Access Point’s
authentication type setting and chooses the right type accord-
ingly.
