Using the Belkin Wireless Networking Utility
128-Bit Encryption
As a result of 64-bit WEP's potential security weaknesses, a more
secure method of 128-bit encryption was developed. 128-bit
encryption includes a key length of 104 bits plus 24 additional bits of
system-generated data (128 bits total). Some hardware manufacturers
refer to 128-bit as 104-bit encryption. Most of the new wireless
equipment in the market today supports both 64-bit and 128-bit WEP
encryption, but you might have older equipment that only supports
64-bit WEP. All wireless products from Belkin will support both 64-bit
and 128-bit WEP.
Encryption Keys
After selecting either the 64-bit or 128-bit WEP encryption mode, it is
critical that you generate an encryption key. If the encryption key is
not consistent throughout the entire wireless network, your wireless
networking devices will be unable to communicate with one another.
You can enter your key by typing in the hex key manually, or you can
type a passphrase into the "Passphrase" field and click "Generate"
to create a key. A hex (hexadecimal) key is a combination of numbers
and letters from A–F and 0–9. For 64-bit WEP, you need to enter 10
hex keys. For 128-bit WEP, you need to enter 26 hex keys.
For instance:
AF 0F 4B C3 D4 = 64-bit WEP key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key
The WEP passphrase is NOT the same as a WEP key. Your Card uses
this passphrase to generate your WEP keys, but different hardware
manufacturers might have different methods on generating the keys.
If you have multiple vendors' equipment in your network, the easiest
thing to do is to use the hex WEP key from your wireless router
and enter it manually into the hex WEP key table in your Card's
configuration screen.
WPA
WPA is a new Wi-Fi standard that improves upon the security features
of WEP. To use WPA security, the drivers and software of your
wireless equipment must be upgraded to support it. These updates
will be found on your wireless vendor's website. There are three types
of WPA security: WPA-PSK (no server), WPA (with radius server), and
WPA2.
WPA-PSK (no server) uses what is known as a pre-shared key as
the network key. A network key is a password that is between eight
and 63 characters long. It can be a combination of letters, numbers,
or characters. Each client uses the same network key to access the
