A Privacy Configuration window will then appear.
-26-
Privacy Configuration consists of specifying Security and Certification, as explained in the
following:
Security Tab
In order to join a network, networks may require an encryption key for association. You must
configure the Authentication Mode and Encryption Mode for your keys in the Privacy section of
this menu.
For Authentication Mode:
Open: Requires NO authentication, since it allows any device to join a network without performing
any security check.
Shared: Requires that the station and the access point use the same WEP key to authenticate. This
basically means that WEP must be enabled and configured on both the access point and the client
with a same key, showed as below:
-27-
WPA-PSK: Allows you to gain access to a secured wireless network that the station and the access
point use the same pre-shared key to authenticate. You must type a mixture of numbers and letters
in the Pre-shared key [WPA] section of this menu. You may input either 8-63 ASCII characters or
64 HEX characters. Pre-shared key is usually used for SOHO authentication.
-28-
WPA: Allows you to gain access to a more secured wireless network that requires mutual
authentication between client and access point with a Radius authentication server. This product
supports various EAP types, which require different credential authentication. In order to access the
wireless network, you must select EAP type your service provider supplied in the section of
IEEE802.11X Authentication.
-29-
WPA2-PSK: Like WPA, WPA2-Personal offers authentication via a pre-shared key. Pre-shared
key is usually used for Personal authentication. Personal mode requires only an access point and
client on the network. Similarly, you need to type a mixture of numbers and letters in the
Pre-shared key [WPA] section of this menu. You may input either 8-63 ASCII characters or 64
HEX characters. Choose WPA2-PSK if needed from Authentication Mode.
-30-
WPA2: WPA2 provides a stronger encryption mechanism than WPA. WPA2 is the second
generation of WPA security, providing personal and enterprise users with a high level of assurance
that only authorized users can access to their wireless network. There is no difference between
WPA and WPA2. The only difference is that WPA2 provides a stronger data encryption via the
AES, contrast to WPA, which uses Temporal Key Integrity Protocol (TKIP). Choose WPA2 if
needed from Authentication Mode.
-31-
Once you choose your Authentication Mode, you then need to select the Encryption Mode.
For Encryption Mode
WEP: Specify the encryption keys. There are two methods to set the WEP keys, as described
below:
Key will be generated automatically for data private
To create encryption keys automatically, click the Key will be generated automatically for data
private check box.
Note: This function is used in IEEE802.1X Authentication mode. Keys are dynamically
generated and distributed by the authentication server. Actually, you can obtain keys by
asking your service provider for further configuration and information to gain access to
the wireless network.
-32-
Pre-configured key [WEP]
You can also create encryption keys manually by pulling down the Key Length menu and select
either 64bit or 128bit encryption method in the Pre-configured key section of this menu.
For 64bit encryption you may choose:
Alphanumeric: entering 5 characters (case sensitive) ranging from “a-z”, “A-Z” and
“0-9” (e.g. MyKey).
Hexadecimal: entering 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9”
(e.g. 11AA22BB33, showed as below).
For 128bit encryption you may choose:
Alphanumeric: entering 13 characters (case sensitive) ranging from “a-z”, “A-Z” and
“0-9” (e.g. MyKey12345678).
Hexadecimal: entering 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9”
(e.g. 00112233445566778899AABBCC).
After you type, the utility uses an algorithm to generate 4 keys automatically. The Key index field
allows you specify which of the four keys you use to transmit 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 Points.
After entering the WEP keys in the key field, click the OK button to make the setting take effect.
TKIP: A greatly enhanced wireless encryption scheme. Designed to enhance protection by most
popular WPA-capable devices. When TKIP is enabled, the key value will be generated
automatically for data private.
AES: A sophisticated wireless encryption scheme. Designed to increase the strength and
complexity of wireless encryption. When AES is enabled, the key value will be generated
automatically for data private.
If the Security you are configuring requires authentication, simply go to the IEEE802.1X
Authentication section of this menu to choose an EAP type.

Current Tx Rate: Shows the highest transmit rate of the current association.
Throughput: Shows the short term transmit and receive throughput in bytes/second, and is
continuously updated.
Link Quality: Based on the quality of the received signal of the Access Point beacon. There are 5
states of link quality:
100%~80%: Excellent link.
80%~60%: Good link quality.
60%~40%: Fair link quality.
Under 40%: Poor or no connection.
Signal Strength: Based on the received signal strength measurement of the baseband processor of
the Beacon signal. Same as link quality, there are 5 states of signal strength:
100%~80%: Excellent signal strength.
80%~60%: Good signal strength.
60%~40%: Fair signal strength.
Under 40%: Poor or no signal strength.
You can click the Rescan button to force the radio to rescan all available channels. If your link
quality or signal strength is poor, rescanning can be used to push the radio off a weak Access Point
and search for a better link with another Access Point.
