1 Introduction
1.1 Overview
Thank you for choosing this Wireless Broadband Router. This Wireless Broadband Router is a multi-function device featuring a wireless 54Mbps Access Point, a 4-port LAN switch and a WAN port, which extends the existing broadband Cable/ADSL connection. It allows the Internet connection to be shared through either the 54Mbps Access Point feature or the 10/100Base-TX Ethernet switch, which also eliminates the purchase of additional hub or switch. Now the wired and wireless networks are integrated to allow various applications to access the Internet.
With the support of the newly emerged 802.11g standard, the Access Point provides data transfer of up to 54 Mbps, up to 5 times faster than 802.11b. Since 802.11g operates on the same frequency of 2.4 GHz as 802.11b, it is backwards compatible with existing Wi­Fi 802.11b devices. The benefit is that you can preserve the existing
802.11b infrastructure while migrating to the new 802.11g infrastructure.
The router has a DHCP server that automatically assigns IP addresses to your LAN or WLAN devices. With the built-in Network Address Translation (NAT) function, your LAN/WLAN can access the Internet through a single external IP address and at the same time protected from outside intruders. The router can also be configured to filter internal access to the Internet. It is designed to provide a reliable Internet access solution for the corporate environment as well as for the small office home office (SOHO).

3 Configuring Local Computer to
Access the Wireless Router
This chapter describes how to configure a computer for initial connection to the device.
3.1 Overview
To access the Wireless Broadband Router’ s Web-based Configuration Utility, at least one properly configured PC must be connected to the device and reside on the same subnet with the Wireless Broadband Router. The easiest way to make the connection is attaching your host computer’ s network card directly to the LAN port of the device.
Whatever your connection method is, the computer’ s Ethernet /wireless interface must be on the same subnet as the router. As the Wireless Broadband Router is configured with these default values:
IP address: 192.168.1.1
Subnet mask: 255.255.255.0
DHCP server: Enabled with the IP address pool from
192.168.1.100 to 192.168.1.150.
So you should set up your NIC or wireless adapter’ s TCP/IP settings as one of the following:
1. To use dynamic IP: Set your PC to be DHCP client to accept the dynamic IP from the router’ s DHCP server.
2. To use static IP: Set the IP address as 192.168.1.x (x is between 2 and 254), subnet mask as 255.255.255.0 and the gateway as 192.168.1.1
The default TCP/IP setting for Windows is acting as a DHCP client. Please proceed to the next section to verify or, if necessary, to configure the TCP/IP settings.

4.3 WAN Configuration – Router Mode
Prior to configuring the Wireless Broadband Router, you must decide whether to configure the device as a router or as a bridge. This section only describes how to set up the device to act as a router. For bridge configuration, see “4.4 WAN Configuration – Bridge Mode” for instructions.
NAT Routing allows the device to act as a router and use the built­in NAT function to translate your multiple private IP addresses into a single public IP address. However, only outgoing requests are allowed to pass through the device unless you specify otherwise, see “4.8 Filters (Router Mode Only)”. Outside users cannot see your private local IP addresses. This leaves your home or business network hidden from outside intruders, see “4.9 Forwarding (Router Mode Only)”.
Click WAN in the configuration menu to enter the WAN configuration page and carry out the procedures below.
Part 1 Configuring general settings
1. WAN/LAN Relation: select the NAT Routing option (factory
default option).
2. Protocol: select a protocol type to indicate how the Wireless
Broadband Router connects with the existing network environment.
3. MAC Address: Leave the default values if it is not necessary to
enter another MAC address. This field allows cloning another network adapter’ s MAC address to the Wireless Broadband Router’ s address. Some ISPs use the MAC address of NIC, which is connected to your Cable/ADSL modem, for static mapping and thus giving you the same IP address each time the Cable/ADSL modem requests for IP address for the Ethernet port. If this is the case, this feature eliminates the need of asking the ISP or network administrator to change the registered MAC address and you can still use the same given IP for the router’ s WAN port.
23
Page 34
Wireless Broadband Router User Manual
3. Host Name: If required, enter a host name for this router. Some
ISPs only respond to a DHCP request with a valid “Host Name”. If a host name is not necessary for your ISP/network environment, just leave it blank.

Part 2. Configuring protocol-specific settings
According to the Protocol selected above, enter the related parameters.
u DHCP Client
If DHCP Client is your option, no other configuration is needed. You may just click Apply to end your WAN settings. After the connection with the ISP is established, the information provided by the ISP will be displayed in the Status section.

Page 35
Wireless Broadband Router User Manual
Username/Password: Enter the username and password provided by the ISP used to log on to the Internet.
Connection Mode: Select your PPP connection from these options:
Keep Alive: This feature will keep your Internet connection
always alive. The Wireless Broadband Router sends echo requests periodically to the ISP to prevent the connection from being terminated by the ISP.
Connect on Demand: If enabled, the router will trigger a PPP session for connection to the Internet if any client PC on your WLAN/LAN sends out a request for Internet access. However, the router automatically disconnects the PPP session after the WAN connection has been idle for the amount of time you specified in the Max Idle Time box (default, 300 seconds). If your Internet account is billed based on the amount of time of your Internet connection, you probably want to enable this option and enter an idle time value best suitable for your network.
MTU/MRU: Allows you to adjust the Maximum Transmission/Receive Unit in bytes for the WAN interface. The packets larger than the specified values will be fragmented before being transmitted. It’ s suggested not to modify the MTU/MRU settings unless instructed by the ISP.
After you finish the WAN settings, click Apply to enable the changes.

u Manual Config
If Manual Config is your option, configure these fields as required by your ISP.
IP Address/Subnet Mask/Default Gateway: Enter the IP address, subnet mask, and default gateway given by the ISP in respective fields.
DNS Servers: Specifies the IP address of the Domain Name Server. Your LAN side DHCP clients use the DNS to map a domain name to its corresponding IP address and vice versa. Up to three DNS servers are allowed. If no DNS server is specified or the specified servers are not available, the router will automatically assign a DNS server to the DHCP clients.
WINS Servers: Optional for Windows Internet Name Service. Enter the IP addresses of WINS servers if required.
Domain Name: Optional. Enter the domain name for the router. After you finish the WAN settings, click Apply to enable the
changes.

IP Address/Subnet Mask. Enter the IP address and subnet mask for the Wireless Broadband Router LAN port. All local wired/wireless devices communicate with the device through this port. It is also the IP address of the Web-based Configuration Utility. By default, the IP address and subnet mask of the LAN port is 192.168.1.1 and
255.255.255.0 respectively. Note that if you change the private IP address and apply the changes, the PC from which you configure the router will lose the communication to the router. To reconnect, you will need to renew the IP address of the PC or change to an IP address compatible with the new LAN port IP address.
28
u DHCP Server (Router Mode Only)
Services: Select whether to enable DHPC service for LAN and
WLAN. The Wireless Broadband Router implements a built-in DHCP (Dynamic Host Configuration Protocol) server on its LAN and WLAN interface, which dynamically assigns IP addresses to the DHCP clients on the LAN / WLAN. The DHCP server also provides a default gateway (the router’ s LAN IP address) and DNS addresses for DHCP clients to access the Internet. DHCP function spares you the hassle of manually assigning a fixed IP address to each PC on the LAN / WLAN. If you already have a DHCP server on your network you should disable this function. DHCP server is enabled by default.
It is not allowed to have two DHCP servers running on one LAN at the same time. If you decide to enable the DHCP on this router, remember to disable the DHCP function of the other device.
Note
If DHCP server is enabled, enter the fields below:

Allow: If selected, only the wireless client whose MAC
address is in the Allow List is allowed to access this AP.
Deny: If selected, only the wireless client whose MAC
address is in the Allow List is NOT allowed to access this
AP. Others clients are granted access.
Disable: No access control. All the clients are allowed to
access this AP. When entering MAC address in the list, up to 16 MAC entries are
allowed.
u Advanced Configuration
It’ s not recommended to modify the Advanced parameters unless specific requirement is needed. The parameters are described as below:
34
Radio: Choose whether to enable or disable the RF (Radio Frequency) of the AP.
Band: Displays the operating frequency of the AP. Channel: Varies according to the specified Country. Rate: The default setting, Auto, allows the AP to automatically use
the fastest possible data rate. Selecting a specific rate forces the AP to transmit at a particular speed.
Basic Rate Set: The Default option uses 1 or 2 Mbps for 802.11b and 6, 12 or 24Mbps for 802.11g as the basic rate of your wireless network. The All option uses 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54Mbps. The wireless clients must support the basic rate to successfully associate with the AP.
Fragment Threshold: It determines whether packets will be fragmented and at what size. On an 802.11 wireless LAN, packets
Page 45
Wireless Broadband Router User Manual
exceeding the fragmentation threshold are fragmented, i.e., split into, smaller units suitable for the circuit size. On the other hand, packets smaller than the specified fragmentation threshold value are not fragmented.
RTS Threshold: Request to send threshold. It specifies the packet size beyond which the AP invokes its RTS/CTS mechanism. Packets that exceed the specified RTS threshold trigger the RTS/CTS mechanism.
DTIM: Specifies the Deferred Traffic Indicator Map (DTIM) period. This value determines at which interval the AP will send its broadcast traffic. The default value is 3.
Beacon Interval: Defines the periodic interval at which the Access Point sends out a beacon.
54gTM Mode: This item allows you to choose from these communication options:
54g Auto: Both 802.11g and 802.11b clients can
communicate with this AP. The data rate will be
automatically adjusted.
54g Performance: Only 802.11g wirless clients can
communicate with the AP.
54g LRS: LRS stands for Limited Rate Support. This option
is intended to support legacy clients (802.11b). Select this
option if wireless clients are experiencing difficulties to
associate with the AP. This option supports both 802.11g
and 802.11b clients.
802.11b Only: Both 802.11g and 802.11b clients can
communicate with this AP. The data rate will be
automatically adjusted to the one supported by the 802.11b
standard. 54g Protection: Select Off or Auto. The default value is set to Off.
When set to Auto, a protection mechanism will ensure that 802.11b wireless devices will connect to the Access Point when many
802.11g wireless devices are present. However, performance of your 802.11g wireless devices may be decreased.
Enable Xpress ™ Technology: Select Off or Auto. When set to Auto, it increases the bandwidth availability that enables more

4.7 Wireless LAN Security
This page configures the wireless security mode.
u Network Authentication
Network Authentication: Disabled by default. If the local network has an authentication server such as Radius server, the user can
Page 47
Wireless Broadband Router User Manual
enable this function by choosing either 802.1X or WPA. This option fulfills the security that an enterprise needs. If the local network does not have an authentication server, it’ s recommended to use WPA- PSK (Pre-Shared Key). This option is commonly used in small office home office (SOHO) environments.
WPA Pre-Shared Key: If WPA-PSK is the network authentication option, enter a secret key. Check the table below for instructions when entering the key.
Format Minimum Characters Maximum Characters
ASCII 8 63 Hexadecimal 8 64
WPA Group ReKey Interval: For WPA and WPA-PSK only. Specifies the timer the WPA key must changes. The change is done automatically between the server and the client.
Radius Server: For 802.1X and WPA only. Enter the IP Address of the authentication server, commonly the Radius server.
Radius Port: Enter the port number of the authentication server. The default port number is 1812.
Radius Key: Enter the same key as the Radius server’ s.
u WEP
Data Encryption: Specifies the encryption mode that the AP uses to transmit the data. Encryption type changes according to the Network Authentication mode. Encryption protects your wireless network against eavesdropping.
Off: The data is not encrypted when it is transferred from
one station to another. This is the default option.
WEP: Only for 802.1X or when authentication is disabled.
The data is encrypted with the WEP algorithm before being
transmitted. If WEP is selected, enter the values in the
Network Key fields.
TKIP: Only for WPA and WPA-PSK. Temporal Key
37
Page 48
Wireless Broadband Router User Manual
Integrity Protocol (TKIP) utilizes a stronger encryption
algorithm and includes Message Integrity Code (MIC) to
provide protection against hackers.
AES: Only for WPA and WPA-PSK. Advanced Encryption
System (AES) utilizes a symmetric 128-Bit block data
encryption. It’ s the strongest encryption currently available. Shared Key Authentication: Authentication is a process in which
the AP validates whether the wireless client is qualified to access the AP’ s service. Select Optional or Required.
Optional: The authentication is done through a pseudo
process, accepting all kinds of requests, mainly used in
cases where connectivity is more important than security.
Required: Utilizes WEP capability to further verify if a
wireless client is authorized to share this AP’ s resource. If
the client has the wrong key or no key, the authentication
will fail and will not be allowed to associate with the AP. If you select Optional, wireless stations with or without correct WEP
keys can be authenticated by the AP. If Required is selected, you must enable WEP function and define
your WEP keys. The keys are used both to authenticate wireless clients and encrypt outgoing data.
38
Network Key 1~4: Enter one to four WEP keys in either ASCII or Hexadecimal format. You can use 64 bits or 128 bits as the encryption algorithm.
Note that when using Hexadecimal format, only digits 0-9 and letters A-F, a-f are allowed. Valid key length for each encryption type is as below:
Key Length HEX Format ASCII Format
64 Bit 10 hexadecimal digits 5 ASCII characters 128 Bit 26 hexadecimal digits 13 ASCII characters
Current Network Key: Aside from entering the WEP keys, select one of the entered keys to encrypt the data before transmission. The AP always transmits data encrypted using the selected WEP Key. The receiving station will use the key number to determine which
Page 49
Note
Wireless Broadband Router User Manual
key to use for decryption. If the key value does not match with the transmitting station, the decryption will fail. To ensure successful decryption, have your wireless stations set identical key tables.
All Wireless Stations must use identical encryption/authentication method and Key values (same key position in its key table) to ensure successful data transmission.

4.9 Forwarding (Router Mode Only)
This page allows you to configure the Forwarding feature. Unlike Filter, which governs outgoing traffic, Forwarding is used to control external access to the local network. This is commonly used when you have publicly accessible virtual servers on your local network.
By default, forwarding entry is empty and any external access to your LAN is blocked. Once you define a forwarding entry, incoming packets (identified by its port number) that match your Forwarding criteria will be forwarded to the port range of the specified local machine. Otherwise packets are blocked. Forwarding serves as a
Page 53
Wireless Broadband Router User Manual
measure of security that protects your network from hazardous packets.
However, if you designate a DMZ (De-Militarized Zone) IP Address, incoming packets that do not match the forwarding criteria will be redirected to the DMZ IP address. That is, forwarding demands a higher priority than DMZ.
u DMZ IP Address
DMZ allows specifying a local machine to be exposed to the Internet. If you specify a DMZ host here, the incoming packets containing no port information specified in the Forwarding table are forwarded to the DMZ host.
u Port Forwards

5 Troubleshooting
I cannot access the Web-based Configuration Utility from the Ethernet computer used to configure the router.
Check that the LAN LED is on. If the LED is not on, verify
that the cable for the LAN connection is firmly connected.
Check whether the computer resides on the same subnet
with the router’ s LAN IP address.
If the computer act as a DHCP client, check whether the
computer has been assigned an IP address from the DHCP
server. If not, you will need to renew the IP address. See
the check/renew IP address section under ‘ 3.2 Setting up
TCP/IP’ for instructions.
Use the ping command to ping the router’ s LAN IP address
to verify the connection.
Make sure your browser is not configured to use a proxy
server.
Check that the IP address you entered is correct. If the
router’ s LAN IP address has been changed, you should
enter the reassigned IP address instead.
I can browse the router’s Web-based Configuration Utility but cannot access the Internet.
Check if the WAN LED is ON. If not, verify that the physical
connection between the router and the DSL/Cable modem
is firmly connected. Also ensure the DSL/Cable modem is
working properly.
If WAN LED is ON, open the System Overview page of the
Web configuration utility and check the status group to see
if the router’ s WAN port has successfully obtained an IP
address.
Make sure you are using the correction method (DHCP
client, PPPoE client, or Manual Config) as required by the
ISP. Also ensure you have entered the correct settings
49
Page 60

provided by the ISP.
For cable users, if your ISP requires a registered Ethernet
card MAC address, make sure you have cloned the
network adapter’ s MAC address to the WAN port of the
router. (See the MAC Address field in WAN page.)
My wireless client cannot communicate with another Ethernet computer.
Ensure the wireless adapter functions properly. You may
open the Device Manager in Windows to see if the adapter
is properly installed.
Make sure the wireless client uses the same SSID and
security settings (if enabled) as the Wireless Broadband
Router.
Ensure that the wireless adapter’ s TCP/IP settings are
correct as required by your network administrator.
If you are using a 802.11b wireless adapter, check that the
54gTM Mode item, in Wireless LAN (2.4G) page, is not
configured to use 54g Performace.
Use the ping command to verify that the wireless client is
able to communicate with the router’ s LAN port and with the
remote computer. If the wireless client can successfully
ping the router’ s LAN port but fails to ping the remote
computer, then verify the TCP/IP settings of the remote
computer.
