high traffic flows along in the wireless network. If the 802.11g MIMO Wireless Router often
transmit large files in wireless network, you can enter new Fragment Threshold value to split
the packet. The value can be set from 256 to 2346. The default value is 2346.
RTS Threshold: RTS stands for “Request to Send”. This parameter controls what size data
packet the low level RF protocol issues to an RTS packet. RTS Threshold is a mechanism
implemented to prevent the “Hidden Node” problem. If the “Hidden Node” problem is an issue,
please specify the packet size. The RTS mechanism will be activated if the data size exceeds
the value you set. The default is 2347.
Tx Power: TX Power measurement.
Short Preamble: Select Disable or Enable this function, default setting is Disable. A preamble
is a signal used in wireless environment to synchronize the transmitting timing including
Synchronization and Start frame delimiter.
Short Slot: When short slot is Enable, the wireless device uses the short slot time only when
all clients associated to the 802.11g, 2.4-GHz radio supports short slot time. Short slot time is
an 802.11g-only feature and does not apply to 802.11a radios.
Tx Burst: Enable the transmitted time slot can increase transmission throughput.
Pkt_Aggregate: The parameter can be used to increase the delivered bandwidth in
community networks including fixed and mobile stations.
Country Code: Select your local Country code for pull-down menu. For Safety (FCC or CE
rule) reason, please don’t change this default setting.
WMM Capable: Enable/Disable the Wi-Fi Multimedia (WMM) support.
APSD Capable: Enable/Disable the APSD support.
WMM Parameters: Click “WMM Configuration” to setup the WMM function.
3.5.3 Security
This function allows you setup the wireless security. Setup the wireless security and
encryption to prevent from unauthorized access and monitoring.
40
SSID Choice: Select the SSID which you want to configure.
Security Mode: This function allows you setup the wireless security. Enable security mode
could prevent any unauthorized access to your wireless network. [Open: If your wireless router
is using “Open” authentication, then the wireless adapter will need to set to the same
authentication type. Shared: Shared key is when both the sender and the recipient share a
secret key. WPA, WPA-PSK, WPA2, WPA2-PSK, WPA-PSK/WPA2-PSK, and WPA1/WPA2:
WPA-PSK offers two encryption methods, TKIP and AES. Select the type of algorithm, TKIP or
AES and then enter a WPA Shared Key of 8~64 characters in the WPA Pre-shared key field.]
Encryption Type: For Open & Shared authentication mode, the selection of encryption type
are None and WEP. For WPA, WPA2, WPA-PSK, and WPA2-PSK authentication mode, the
encryption type supports both TKIP and AES.
WPA Pre-shared Key: This is the shared secret between AP and STA, For WPA-PSK and
WPA2-PSK authentication mode, this field must be filled with character longer than 8 and less
then 64 lengths.
WEP Key: Only valid when using WEP encryption algorithm. The key must match with the
AP’s Key. There are several formats to enter the keys.
-- Hexadecimal (128bits): 26 Hex characters (0-9, a-f)
-- ASCII (128bits): 13 ASCII characters.
WPA Algorithms: Select TKIP, AES, TKIP/AES for the WPA Algorithms.
Enable Pre-Authentication: The two most important features beyond WPA to become
41
standardized through 802.11i/WPA2 are: pre-authentication, which enables secure fast
roaming without noticeable signal latency.
RADIUS Server: RADIUS is an authentication, authorization and accounting client-server
protocol. The client is a Network Access Server that desires to authenticate its links. The
server is a server that has access to a user database with authentication information.
IP Address: Enter the RADIUS Server’s IP address provided by your ISP.
Port: Enter the RADIUS Server’s port number provided by your ISP. The default is 1812.
Shared Secret: Enter the password that the router shares with the RADIUS Server.
Capable: Specify the SSID’s capability.
New: For security reason, enter the MAC address in this section can prevent others to connect
this wireless router.
3.5.4 WPS
You could setup security easily by choosing PIN or PBC method to do Wi-Fi protected setup.
Wi-Fi Protected Setup was designed to ease setup of security enabled WiFi networks in the
home and small office environment. It supports methods that are familiar to most consumers to
configure a network and enable security, like pushing a button (PBC method) or entering a PIN
code (PIN method). The new system, which will be incorporated in Windows Vista, will work
with computers, gateways peripherals, and consumer electronics.
You would initiate a WPS mode on gateway and then enter a simple sequence of digits (like a
PIN code) or press a button, use a similarly easy method to start a secure key exchange to
retrieve the WPA/WPA2 key.
This function allows you to change the setting for WPS (Wi-Fi Protected Setup). WPS can help
42
your wireless client earlier automatically connect to the Access Point.
[WPS Summary]
From this section, you can view the current WPS status, Configured, SSID, Auth mode,
Encrypt Type, Default Key Index, WPS Key, and AP PIN information.
Reset OOB: Click this button to rest the settings.
[WPS Progress]
WPS Mode: Specify the AP router acts as a Registrar or an Enrollee.
In PIN method (PIN-Personal Identification Number), When your 11n router acts as a
Registrar, your must enter “Add Enrollee PIN code” on WPS config section, this Enrollee PIN
code should be provided by the Enrollee. If your 11n router acts as a Enrollee, in WPS config
section, the “PIN code of this AP” will automatically generate for you. The purpose of PIN
code is to provide the security key to Registrar (AP/Server). Therefore, WPS (Wi-Fi Protected
Setup) can be established completely.
In PBC Method (PBC-Push Button Communication), while the AP router acts as Registrar or
Enrollee, and click “Start WPS Config” button, the WPS (Wi-Fi Protected Setup) will establish
the connection automatically.
PIN: Enter the PIN code from the registrar or enrollee.
WPS Status: Here shows the current status of the WPS function.

3.6 Firewall
The Firewall contains the following sections:
◎MAC/IP/Port Filtering
◎System Security Setting
◎Port Forwarding ◎DMZ
◎Content Filtering ◎Port Trigger
3.6.1 MAC/IP/Port Filtering Settings
You can setup firewall rules to protect your network from virus, worm and malicious activity on
the internet. Filters are used to deny or allow LAN computers from access the Internet. Within
the local area network, the unit can be setup to deny Internet access to computers using the
assigned IP or MAC addresses. The unit can also block users from accessing restricted web
site.
MAC/IP/Port Filtering: Enable this function, all list from the filtering will be deny the internet
access.
Default Policy: There have 2 options, Dropped and Accepted.
45
MAC Address: The MAC address of the computer in the LAN (Local Area Network) to be
used in the MAC filter table. Enter the MAC address of LAN port, e.g. 00:00:27:88:81:18
Dest IP Address: The IP address that will be denied to access.
Source IP Address: The IP address that will be denied access to the Internet.
Protocol: This is the protocol type that will be used with the Port that will be blocked.
Destination Port Range: The single port or port range that will be denied to access. If no port
is specified, all ports will be denied access.
Source Port Range: The single port or port range that will be denied access to the Internet. If
no port is specified, all ports will be denied access.
46
3.6.2 Port Forwarding
You may setup virtual servers to provide service on internet.
Virtual Server Setting: Enable/Disable the port forward.
IP Address: This is the port number on the WAN side that will be used to access the
application. You may define a single port or a range of ports. You can use a comma to add
multiple ports or port ranges.
Port Range: This is the port used to forward the application. It can be either a single port or a
range of ports. For the TCP and UDP services enter the beginning of the range of port
numbers used by the service. If the service uses a single port number, enter it in both the start
and finish fields.
Protocol: Select the protocol (TCP, UDP, or TCP & UDP) used to the remote system or
service.
Comment: You may key in a description for the IP address.
47
3.6.3 DMZ
You may setup a De-Militarized Zone (DMZ) to separate internet network and internet.
DMZ Setting: If the DMZ Host Function is enabled, it means that you set up DMZ host at a
particular computer to be exposed to the Internet so that some applications/software,
especially Internet/Online game can have two-way connections. Select Enable or Disable from
the pull-down menu.
DMZ IP Address: Enter the IP address of a particular host in your LAN that will receive all the
packets originally going to the WAN port/Public IP address above.
Note: You need to give
your LAN PC clients a fixed/static IP address for DMZ to work properly.
48
3.6.4 System Security Settings
You may configure the system firewall to protect AP/Router itself from attacking.
Malformed Packet Detection: Filter the packet’s header unreasonable or unusual, such as IP,
TCP, UDP, and ICMP protocols’ packet.
IP Land Attack: When packet’s source IP and destination IP are same and the source port is
also same as destination port, the packet is determined the IP Land attack and dropped by the
router.
IP Spoof: The packet from WAN and the source IP network is same as LAN IP network, this
packet is determined the IP Spoof attack and dropped by the router.
