Chapter II: System and Network Setup
2-1 Installation
Follow the instructions below to build the network connection between
your new Wireless router and your computers, network devices:
1. Connect your xDSL / cable modem to the WAN port of the router by
Ethernet cable.
2. Connect your computers and network devices (network-enabled
consumer devices other than computers, like game consoles, or a
switch / hub) to an available LAN port of the router.
3. Insert the A/C power adapter into the wall socket, and then connect
it to the ‘Power’ socket of the router.
16
4. Check all LEDs on the front panel. The ‘Power’ LED should be steadily
on, WAN and LAN LEDs should be on if the computer / network
devices connected to the respective port of the router is powered on
and correctly connected. If the Power LED is not on, or any LED you
expected to be on is not on, recheck the cabling, or jump to ‘4-2
Troubleshooting’ for possible reasons and solutions.

2-2 Connecting to the wireless broadband router by web
browser
Before you can connect to the router and start configuration procedures,
your computer must be able to get an IP address automatically (using a
dynamic IP address). If it’s set to use a static IP address, or you’re unsure,
follow the instructions below to configure your computer to use
dynamic IP address:
18
2-2-1 Windows 7 IP address setup:
1. Click the ‘Start’ button (it should be located at the lower-left corner of
your computer screen), then click control panel. Click View Network
Status and Tasks, and then click Manage Network Connections.
Right-click Local Area Network, then select ‘Properties’. The Local Area
Connection Properties window will appear, select ‘Internet Protocol
Version 4 (TCP / IPv4), and then click the ‘Properties’ button.
19
2. Select ‘Obtain an IP address automatically’ and ‘Obtain DNS server
address automatically’, then click the ‘OK’ button.
20
Connect to the router’s management interface by web browser.
Start your web browser, and input the default IP address of the router
in the address bar, type http://192.168.0.1
A dialog box will appear, such as the one below.
Input the user name and password in their respective fields, the default
user name is ‘admin’, and the default password is ‘admin’, then press
the ‘OK’ button, and you can see the Quick Setup interface of this router:
21
NOTE: If you can’t see the web management interface, and you’re being
prompted to input the user name and password again, it means you didn’t
input the username and password correctly. Please retype the user name
and password again. If you’re certain that the user name and password you
type are correct, please go to ‘4-2 Troubleshooting’ to perform a factory
reset, to set the password back to its default value.

though you’re using another connection type, like xDSL.
Choose the WAN (Internet connection) type you’re using on this page.
There are five options for the type of Internet connection:
DHCP Connection (Cable Modem) - go to section 2-3-1
Username / Password Connection (PPPoE) - go to section 2-3-2
Static IP Address Connection (Fixed-IP) - go to section 2-3-3
Username / Password Connection (PPTP) - go to section 2-3-4
Username / Password Connection (L2TP) - go to section 2-3-5
If you’re not sure, contact your Internet service provider. A wrong
Internet connection type will cause a connection problem, and you will
not be able to connect to the Internet.
If you want to go back to the previous step, press the ‘Back’ button on
