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 Belkin wireless products 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 on your network and you will not be
able to successfully communicate within your network.
You can enter your key by typing in the hex key manually, or you can type in a
passphrase in the “Passphrase” field and click “Generate” to create a key. A hex
(hexadecimal) key is a mixture 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 wireless card uses
this passphrase to generate your WEP keys, but different hardware
manufacturers might have different methods for generating the keys. If you have
equipment from multiple vendors in your network, you can use the hex WEP key
from your Router or access point and enter it manually into the hex WEP key
table in your wireless card’s configuration screen.
WPA (Wi-Fi Protected Access)
WPA (Wi-Fi Protected Access) is a new Wi-Fi standard that was designed to
improve upon the security features of WEP. To use WPA security, the drivers
and software of your wireless equipment must be upgraded to support WPA.
These updates will be found on the wireless vendors’ websites. There are two
types of WPA security: WPA-PSK (no server) and WPA (with radius server).
WPA-PSK (no server)
This method uses what is known as a Pre-Shared key as the Network key. A
Network key is basically a password that is between eight and 63 characters long.
It can be a combination of letters, numbers, or characters. Each client uses the
