Figure 72 Security Settings
The IEEE 802.11n Wireless LAN USB Adapter allows you to configure up to four 64-bit, or
128-bit WEP keys and only one key is used as the default key at one time. The Key index field
allows you to specify the key index you desire to use for transmitting data on your wireless
LAN. You can change the default key by clicking on the up or down arrow and make sure the
default key is set up exactly the same on the Wireless LAN stations as they are on the wireless
Access Point.
z For 64bit encryption you may choose:
Alphanumeric: entering 5 characters (case sensitive) ranging from “a-z”, “A-Z” “0-9” to
special characters like “@”, “#”, “$” and so on as long as they are in the ASCII table. (e.g.
My&12).
Hexadecimal: entering 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g.
11AA22BB33, shown as below).
z For 128bit encryption you may choose:
Alphanumeric: entering 5 characters (case sensitive) ranging from “a-z”, “A-Z” “0-9” to
special characters like “@”, “#”, “$” and so on as long as they are in the ASCII table. (e.g.
My#$%12345678).
Hexadecimal: entering 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g.
00112233445566778899AABBCC).
Authentication with WEP: Open System authentication and
Shared Key authentication
z Open system mode is implemented for ease-of-use and when security is not an issue. It
requires NO authentication, since it allows any device to join a network without
performing any security check. The wireless station and the AP do not share a secret key.
Thus the wireless stations can associate with any AP and listen to any data transmitted
plaintext.
z Shared key mode involves a shared secret key to authenticate the wireless station to the
AP. It requires that the station and the access point use the same WEP key to
