What is the WEP Encryption key?
The absence of a physical connection between nodes makes the wireless links vulnerable to
information theft. To provide a certain level of security from eavesdroppers and hackers, you can
enable WEP encryption. The following information is needed to determine the WEP encryption
level.
Note: The Shared Key, as well as the key content used by the HA311 Wireless PCI adapter and the
wireless access point or other wireless nodes in the same network, must be the same. You can
enter up to four different keys in the dialog box (see the screen shot below) but only the selected
key is effective.
Note: Twenty-four bits in the encryption key are factory preset and not modifiable. A 64-bit
encryption key can be represented by ten (10) hexadecimal digits. For a 128-bit encryption key,
twenty-six (26) hexadecimal digits need to be provided. For a 152-bit encryption key, thirty-two
(32) hexadecimal digits need to be provided.
Note: Hexadecimal digits are the first ten numbers of the decimal system (0, 1, 2, 3, 4, 5, 6, 7, 8,
and 9) and the letters A, B, C, D, E, and F. Your choice of characters is arbitrary. You might use,
for example, a phone number. (Do not use an obvious one, such as your office phone number).
The table below shows you some examples of encryption settings.
