- 128 bits
• Key Type—The key type. Select one:
- ASCII
- Hex
• WEP Keys—You can specify up to four WEP keys. In each text box, enter a string of
characters for each key. The keys you enter depend on the key type selected:
- ASCII—Includes uppercase and lowercase alphabetic letters, the numeric digits,
and special symbols such as @ and #.
- Hex—Includes digits 0 to 9 and the letters A to F.
Use the same number of characters for each key as specified in the Characters
Required field. These are the RC4 WEP keys shared with the stations using the WAP
device.
Each client station must be configured to use one of these same WEP keys in the same
slot as specified on the WAP device.
• Characters Required—The number of characters you enter into the WEP Key fields is
determined by the key length and key type you select. For example, if you use 128-bit
ASCII keys, you must enter 26 characters in the WEP key. The number of characters
required updates automatically based on how you set the key length and key type.
• 802.1X Authentication—The authentication algorithm defines the method used to
determine whether a client station is allowed to associate with WAP device when static
WEP is the security mode.
Specify the authentication algorithm you want to use by choosing one of these options:
- Open System authentication allows any client station to associate with the WAP
device whether that client station has the correct WEP key or not. This algorithm is
also used in plaintext, IEEE 802.1X, and WPA modes. When the authentication
algorithm is set to Open System, any client can associate with the WAP device.
Just because a client station is allowed to associate does not ensure it can
NOTE
exchange traffic with an WAP device. A station must have the correct WEP key to
be able to successfully access and decrypt data from the WAP device, and to
transmit readable data to the WAP device.
- Shared Key authentication requires the client station to have the correct WEP key
in order to associate with the WAP device. When the authentication algorithm is set
to Shared Key, a station with an incorrect WEP key cannot associate with the WAP
device.
