STEP 5
If you choose
WEP
as the security mode, enter the following information:
•
Authentication Type:
Choose either
Open System
or
Shared key
, or
choose
Auto
to let the security appliance accept both Open System and
Shared Key schemes.
•
Default Transmit Key:
Choose a key index as the default transmit key. Key
indexes 1 through 4 are available.
•
Encryption:
Choose the encryption type: 64 bits (10 hex digits), 64 bits (5
ASCII), 128 bits (26 hex digits), or 128 bits (13 ASCII). The default is 64 bits
(10 hex digits). The larger size keys provide stronger encryption, thus making
the key more difficult to crack.
•
Passphrase:
If you want to generate WEP keys by using a Passphrase, enter
any alphanumeric phrase (between 4 to 63 characters) and then click
Generate
to generate 4 unique WEP keys. Select one key to use as the key
that devices must have to use the wireless network.
•
Key 1-4:
If a WEP Passphrase is not specified, a key can be entered directly
into one of the Key boxes. The length of the key should be 5 ASCII characters
(or 10 hex characters) for 64-bit encryption and 13 ASCII characters (or 26
hex characters) for 128-bit encryption.
STEP 6
If you choose
WPA-Personal
as the security mode, enter the following
information:
•
Encryption:
Choose either TKIP or TKIP_CCMP (AES) as the encryption
algorithm for data encryption. The default is TKIP.
•
Shared Secret:
The Pre-shared Key (PSK) is the shared secret key for WPA.
Enter a string of at least 8 characters to a maximum of 63 characters.
•
Key Renewal Timeout:
Enter a value to set the interval at which the key is
refreshed for clients associated to this SSID. The valid range is 0 to 4194303
seconds. A value of zero (0) indicates that the key is not refreshed. The
default value is 3600 seconds.
STEP 7
If you choose
WPA2-Personal
as the security mode, enter the following
information:
•
Encryption:
Always use AES for data encryption.
•
Shared Secret:
The Pre-shared Key (PSK) is the shared secret key for WPA.
Enter a string of at least 8 characters to a maximum of 63 characters.
