Field Name
Description
RADIUS Server
Allows you to enter the IP address of the RADIUS server used for
authentication and encryption key derivation.
This field is used with 802.1x and WPA Network
Authentication.
The factory default for this field is 0.0.0.0.
RADIUS Port
Determines the port number of the RADIUS server. The port
number is usually 1812 (factory default) or 1645, depending on the
server used.
This field is used with 802.1x and WPA Network Authentication.
RADIUS Key
Allows you to set the Shared Secret key for your RADIUS
connection.
The factory default for this field is empty.
This field is used with 802.1x and WPA Network
Authentication.
Group Key Rotation
Interval
Allows you to set the WPA Group Key Rotation Interval in seconds.
This only applies when WPA or WPA2 Network Authentication is
enabled.
Set this value to 0 (factory default) to disable periodic rekeying. The
valid range is 1 to 4,294,967,295 seconds.
WPA/WPA2 Re-auth
Interval
Allows you to set the WPA/WPA2 Re-authorization Interval in
seconds. This only applies when WPA/WPA2 Network
Authentication is enabled.
Set this value to 0 (factory default) to disable periodic rekeying. The
valid range is 1 to 4,294,967,295 seconds.

Field Name
Description
WEP Encryption
Allows you to enable data encryption to help secure the data that is
sent over your wireless network.
WEP 128-bit
128-bit or 64-bit static key data encryption can be selected when
the network is configured to have no authentication.
128-bit static key data encryption is automatically selected when
802.1x network authentication is enabled.
Notes:
Static key authentication uses one of the four encryption keys,
as defined below, to encrypt your data. You must manually
change keys. The keys do not change or rotate automatically as
they do with TKIP.
64-bit and 40-bit encryption are two different names for the
same encryption.
128-bit and 104-bit encryption are two different names for the
same encryption.
Shared Key
Authentication
Allows you to determine if Shared Key Authentication is used in the
network. Shared Key Authentication can be used when there is no
other network authentication in the network.
Optional (factory default) - Wireless clients can associate with
the wireless access point without authentication.
Required - Only wireless clients with a valid network key are
allowed to associate with the access point.
802.1x Authentication
Allows you to use 802.1x authentication with WEP encryption
(similar to when WPA or WPA2 is enabled).

Network Keys
1 through 4
64 bit keys
or
Select these keys for use with Encryption Mode set to 64-bit
encryption. Enter 5-byte values for a Key. You do not have to set all
four Keys. Only one Key is used for a home network. Each value is
represented in hexadecimal. Use only these numbers or letters: 0, 1,
2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, and f to set up your encryption keys.
Note:
It is generally a good practice to use only lowercase letters
when entering WEP encryption keys. Uppercase letters can
sometimes be confused with numbers. For example, the uppercase
letter ―B‖ is often mistaken for the number ―8.‖ Using lowercase
characters minimizes the risk of confusing characters when copying
keys from one device to another. Uppercase characters will
automatically be converted to lowercase when the key or keys are
applied and saved to memory.
Use two numbers or letters in each box. Record your Key values.
You will need these Key values when you set up your client
wireless adapter. The Key values in each wireless network device
must match.

value is represented in hexadecimal. Use only these numbers or
letters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, and f to set up your

Current Network Key
Allows you to select which of the four 64-bit or 128-bit keys to use to
encrypt your data when you are using encryption that requires the
manual entry of an encryption key. Only one WEP key is in use at a
time. You must manually change keys. They do not change
automatically.
Notes:
64-bit and 40-bit encryption are two different names for the
same encryption.
128-bit and 104-bit encryption are two different names for the
same encryption.

Field Name
Description
PassPhrase
Automatically generates WEP encryption keys required to
communicate with the network.
Although not required for WEP operation, use of a PassPhrase can
simplify the configuration and setup of each of your client wireless
adapters.
Using a PassPhrase eliminates the need to manual enter lengthy
encryption keys and reduces the chance of error associated with
entering entry of large numbers.
