provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used i n accorda nce with the instruct ions, may cause harm ful interfere nce to radio c ommunic ations. However , there is no guar antee that interfere nce wil l
not occur in a partic ular in st allat ion. If this equipment does c aus e har mfu l inte rferen ce to r adio or t e levis ion recept ion, w hich ca n b e deter mined by turning t he equ ipm ent
off and on, the user is encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separat io n between the equipment and receiver.
- Connect the equipment int o an out l et on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.

1 Safety Precautions
Follow the following instructions to prevent the device from risks and damage caused by fire or electric power:
Use volume labe ls t o mark the type of power .
Use the power ada pt er packed within the device pack age.
Pay attention to the power load o f the outlet or prolonged lines. An overburden power outlet or dam aged lines and plugs may cause electric shock or fire accident.
Check the power cords regul ar ly. If you find any damage, replace it at once.
Proper space left for heat dissipation is necessary to avoid damage caused by overheating to the device. The long and thin holes on the device are designed for
heat dissipation to ensure that the dev ice w orks normally. Do not cover these heat dissipation holes.
Do not put this dev ice close to a place where a heat source exists or high temperature occurs. Avoid the device from direct sunshine.
Do not put this device close to a place where it is over damp or watery . Do not spill any fluid on this device.
Do not conne ct t his dev ice to any PCs or electronic product s, u nless our c ust omer eng ineer or your broa dband pr ovi der i nstruct s y ou to d o t his, becaus e a ny wrong
connection may cause power or fire risk.
Do not place this d evice on an unstable surface or support.

3.1 Choosing the Best Location for Wir el ess Operation
Many environmental factors may affect the effective wireless function of the DSL Router. If this is the first time that you set up a wireless network device, read the
following information:
The access point can be placed on a shelf or desktop, ideally you should be able to see the LED indicators in the front, as you may need to view them for
troubleshooting.
Designed to go up to 100 meter s indoors and up to 300 meters outdo or s , wireless LAN lets you access your network from anywhere you want. Howev er, the numbers
of walls, ceilings, or other objects that the wireless signals must pass through limit signal range. Typical ranges vary depending on types of materials and background
RF noise in your home or busines s.

3.2 Connecting the Router
Connect the DSL port of the router and the Modem port of the splitter
with a telephone cable; connect the phone to the phone port of the
(1)
splitter through a cable; and connect the incoming line to the Line port of
the splitter.
The spliiter has three ports:
LINE: Connect to a w al l phone jack (RJ-11 jack)
Modem: Connect to the Line interface of the router
PHONE: Connect to a telephone set
(2) Connect the LAN port of the router to the network interface card (NIC) of
the PC through an Ethernet cable (MDI/MDIX).
(3) Plug the power adapter to the wall outlet and then connect the other end
of it to the Power port of the router.

Ping the MAINTENANCE IP address (192.168.1.1 by default) of the Router.
4 About the Web Configuration
The first time you setup the Router. It is recommended that you configure the WAN connection using a single computer, to ensure that both the computer and the
Router are not connected to the LAN. Once the WAN connection operates properly, you may continue to make changes to Router configuration, including IP settings
and DHCP setup. This chapter is concerned with using your computer to configure the WAN connection. The following chapter describes the various menus used to
configure and monitor the Router, including how to change IP settings and DHCP server setup.
4.1 Prep aration Before Login
Before accessing the Routerre the communication between PC and Router is normal. Check the commu nication as follows.
255.255.255.0, gateway address as 192.168.1
address of the Router.
If the PC can read the MAC address of the Router and can ping through the
MAINTENANCE IP address of the Router, that means the communication of
the PC and the Router is nor ma l.

When subscribing to a broadband service, you should be aware o f the method, by which you are connected t o the Internet . Your physical WAN dev ice can be Ethernet ,
DSL, or both. Technical information about the properties of your Internet connection is provided by your Internet service provider (ISP). For example, your ISP should
inform you whether you are connected to the Internet using a static or dynamic IP address, or the protocol, such as PPPoA or PPPoE, that you use to communicate
over the Internet.

Authentication Method:
MSCHAP. Usually, you can select AUTO.
Dial on demand (with idle timeout timer): If thi s function is enabled,
you need to enter the idle timeout time. Within the preset minutes, if the
router does not detect the flow of the user continuously, the router
automatically stops the PPPoE connection. Once it detects the flow (like
access to a webpage), the router restarts the PPPoE dialup.
If this function is disabled, the router performs PPPoE dial-up all the
time. The PPPoE connnection does not stop, unless the router is
powered off and DSL AM or uplink equipment is abnormal.
MTU Size: Maximum Transmission Unit. Sometimes, you must modify
this function to access network successfully.
PPP IP extension: If this function is enabled, the WAN
obtained by the router through built-in dial-up can be directly assigned to
the PC being attached to the router ( at this time, the router connects to
only one PC). From the aspect of the PC user, the PC dials up to obtain
an IP addres. But actually, the dial-up is done by the router. If this
function is disabled, the router itself obtains the WAN IP address.
Use Static IP Address: If this function is disabled, the router obtains an
IP address assigned by an uplink equipment such as BAS, through
PPPoE dial-up.
If this function is enabled, the router uses this IP address as the WAN IP
address.
Enable NAT : Select it t o enable the NAT functions of the router. If you do
not want to enable NAT and wish the router user to access the Internet
normally, you must add a route on the uplink equipment. Otherwise, the
access to the Internet fails. Normally, NAT should be enabled.
Enable Firewall: Enable or disable IP filtering.
Enable IGMP Multicast: IGMP proxy. For example, if you w ish that the
