wireless client, which can be either 8 to 63 text characters or 64 hexadecimal (hex) characters.
The only allowable hexadecimal characters are 0-9, and A-F. This option is available when
Personal (Pre-shared Key) is selected from
Authentication
type.
RADIUS Secret
Displays the RAIUS server’s secret that it shares with the Gateway. This option is available
when Enterprise (802.1x) is selected from
Authentication
type.
RADIUS Server
IP Address
Displays the RAIUS server’s IP address used for authentication purposes. This option is
available when Enterprise (802.1x) is selected from
Authentication
type.
RADIUS Port
Displays the RAIUS server’s port. This option is available when Enterprise (802.1x) is
selected from
Authentication
type.
WPA Group
ReKey Interval
Displays the number of seconds between rekeying the WPA group key. 0 means that rekeying
is disabled. By default, WPA Group ReKey Interval is set to 3600.
To configure WPA security, please follow these steps:
1.
Select the
Authentication Type
method from the drop-down menu.
•
Personal (Pre-Shared Key)
must use 8 to 63 text characters or 64 hexadecimal digits to authenticate the
wireless adapter.
•
Enterprise (802.1x)
authentication uses a third
-
party radius server to authenticate the wireless adapter.
2.
Select the
WPA Type
from the drop-down menu:
•
WPA Mixed
– Enables stations that support WPA v.1 or WPA v.2 to connect to the AP.
•
WPA
– Enables stations that support WPA v.1 to connect to the AP.
•
WPA2
– Enables stations that support WPA v.2 to connect to the AP.
3.
Select the
Data Encryption
from the drop-down menu:
•
TKIP
– Temporal key Integrity Protocol
•
AES
– Advanced Encryption Standard
•
TKIP + AES
– Accepts either TKIP or AES encryption
If
Enterprise (302.1x)
was selected as the
Authentication Type
in step 1, type the following information in the
fields provided:
•
RADIUS Secret
– The secret that the AP shares with the RADIUS server.
•
RADIUS Server IP Address
– The RADIUS server’s IP address used for authentication.
•
RADIUS Port
– The RADIUS server’s port.
If Personal (Pre-shared Key) was selected as the Authentication Type in step 1, type the following information in the
field provided:
•
WPA Shared Key
– This is a passphrase (also called a shared secret) that must be typed into both the
wireless Gateway and the wireless client. This shared secret can be between 8 to 63 text characters (or 64
hexadecimal characters) and can include special characters and spaces. The WPA Shared Key should be a
random sequence of either keyboard characters (upper and lowercase letters, numbers, and punctuation), at
least 20 characters long, or hexadecimal digits (numbers 0-9 and letters A-F) at least 24 hexadecimal digits
long. The more random your WPA Shared Key, the safer it is to use.
4.
Type the
WPA Group ReKey Interval
in the field provided. This is the number of seconds between rekeying
the WPA group key. A zero “0” means that rekeying is disabled.
5.
Click the
save
button.
After you have typed in your values and clicked
save
in the
WPA
screen, a pop-up screen appears, indicating that

MAC Filtering
The following screen will appear if you select
Wireless > MAC Filtering
from the main menu. This feature allows
only wireless stations that have been added to the MAC Filtering table to have access to the Gateway. All other
stations will be blocked. This is an effective way to ensure that only those devices you designate can join your
network. However, it does not replace other security measures. With security turned off and MAC filtering turned
on, unwanted (unauthorized) stations cannot connect to your network, but they can still eavesdrop on your
unsecured data transmissions.
MAC address

Beacon Period
Displays the time interval between beacon frame transmissions. Beacons contain rate and
capability information and are used to identify the access points in the area.
RTS
Threshold
Displays the
Request to Send/Clear to Send (RTS/CTS) handshaking performed for any data or
management packet containing a number of bytes greater than the threshold. If this value is larger
than the packet size (typically set by the fragmentation threshold), no handshaking will be
performed. A value of 0 will enable handshaking for all MPDUs (MAC Protocol Data Unit).
Fragmentation
Threshold
Displays the
packet size value where numbers larger than this value will be fragmented into
multiple packets of the specified size or smaller.
Supported
Rates
Click these drop-down menus to select the allowable communication rates the Gateway will
attempt to use. The rates are also broadcast within the connection protocol as the rates supported
by the Gateway. Each Mode has a corresponding set of default Supported Rate values. These
default values may be changed as desired.
•
N: not supported: This rate is not supported for transmit.
•
Y: supported: This rate is supported.
•
B: basic supported: This rate is supported. Only stations that support all of these basic
rates will associate with the Gateway.
