&AES.
2. Security Key: Enter a security key, which must be between 8-63 ASCII characters long.
3. Key Update Interval: Enter a valid time period for the key to be changed.
WPA2-PSK
WPA2 (Wi-Fi Protected Access version 2) is based on 802.11i and uses Advanced Encryption Standard
(AES) instead of TKIP. It is more secured than WPA and WEP.
1. Cipher Type: Select AES (advanced encryption standard) or TKIP (temporary key integrity protocol)
&AES.
2. Security Key: Enter a security key, which must be between 8-63 ASCII characters long.
3. Key Update Interval: Enter a valid time period for the key to be changed.
3.5.3 WDS
Wireless distribution system (WDS) is a system enabling the wireless interconnection of access points in
an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points
without the traditional requirement for a wired backbone to link them. Note: The Access Points you select
must support WDS.
11
Access Point
1. WDS Mode: Select Disable, Repeater Mode or Bridge Mode.
2. AP MAC Address: Displays the remote AP’s MAC address.
For Example:
Access Point 1 LAN IP: 192.168.0.254

WDS Mode: Repeater Mode
Configure Access Point 1:
1)Click Open Scan to select the remote AP and click OK to add the corresponding MAC address
automatically.
2) Click OK to save your settings.
12
Access Point
Then follow the steps mentioned above to configure the Access Point 2. After the two APs have added
each other, they can be bridged successfully.
Note ----------------------------------------------------------------------------------------------------------------------------1. In WDS mode, the two APs should support WDS and you should keep their SSIDs, channels, security
modes and keys the same. As for IP address, they should not be the same but on the same network
segment;
2. Once the security mode has been changed, please reboot the device.
3. If one of the APs is in Bridge Mode, the remote one must be in Repeater Mode.
4. In Bridge mode, clients won’t be able to access the device’s primary SSID.
-----------------------------------------------------------------------------------------------------------------------------------------
3.5.4 Universal Repeater
Select Universal Repeater and enable scan to automatically populate SSID and channel of the AP to
connect or manually enter the AP's SSID, channel and security key.
Note ----------------------------------------------------------------------------------------------------------------------------1. Enabling scan does not populate the security key, so you must still manually enter it.
2. Make sure your (local) AP, PCs connected and the remote AP to connect are on the same subnet with
different IP addresses.
3. If ping requests sent from PCs connected to your local AP are properly replied by the targeted remote
AP, Universal Repeater is successfully operating; if not, check your settings again.
----------------------------------------------------------------------------------------------------------------------------------------13

Appendix 1 Glossary
Channel
A communication channel, also known as channel, refers either to a physical transmission medium such
as a wire or to a logical connection over a multiplexed medium such as a radio channel. It is used to
transfer an information signal, such as a digital bit stream, from one or more transmitters to one or more
receivers. If there is only one AP in the range, select any channel you like. The default is Auto.
If there are several APs coexisting in the same area, it is advisable that you select a different channel for
each AP to operate on, minimizing the interference between neighboring APs. For example, if 3
American- standard APs coexist in one area, you can set their channels respectively to 1, 6 and 11 to
avoid mutual interference.
SSID
Service set identifier (SSID) is used to identify a particular 802.11 wireless LAN. It is the name of a
specific wireless network. To let your wireless network adapter roam among different APs, you must set
all APs’ SSID to the same name.
WEP
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or 152-bit
shared key algorithm, as described in the IEEE 802.11 standard.
WPA/WPA2
The WPA protocol implements the majority of the IEEE 802.11i standard. It enhances data encryption
through the Temporal Key Integrity Protocol (TKIP) which is a 128-bit per-packet key, meaning that it
dynamically generates a new key for each packet. WPA also includes a message integrity check feature
to prevent data packets from being hampered with. Only authorized network users can access the
wireless network. The later WPA2 protocol features compliance with the full IEEE 802.11i standard and
uses Advanced Encryption Standard (AES) in addition to TKIP encryption protocol to guarantee better
security than that provided by WEP or WPA. Currently, WPA is supported by Windows XP SP1.
