Chapter 2 - Installation
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if you are using the
device as a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored on another computer or gateway
device, not in the Router itself.
If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection can be stored
in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some settings in the device, including
account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled device on the LAN
side of the bridge, such as a PC, a server, a gateway device, such as a router, or similar firewall hardware. The IP address can be assigned in a number of ways.
Your network service provider will give you instructions about any additional connection software or NIC configuration that may be required.
Wireless LAN
Computers using the wireless network can access the Internet using the embedded wireless access point. Wireless workstations must have an 802.1n, 802.1g, or
802.1b wireless network card installed to use the Router. In addition, the workstation must be configured to operate on the same channel and SSID as the Router. If
wireless security is used, the wireless workstations must be properly configured for the security settings used.

Chapter 2 - Installation
Information you will need from your ADSL service provider
Username
This is the Username used to log on to your ADSL service provider’s network. Your ADSL service provider uses this to identify your account.
Password
This is the Password used, in conjunction with the Username above, to log on to your ADSL service provider’s network. This is used to verify the identity of your account.
WAN Setting / Connection Type
These settings describe the method your ADSL service provider uses to transport data between the Internet and your computer. Most users will use the default settings.
You may need to specify one of the following WAN Setting and Connection Type configurations (Connection Type settings listed in parenthesis):
y
PPPoE/PPPoA (PPPoE LLC, PPPoE VC-Mux, PPPoA LLC, or PPPoA VC-Mux)
y
Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)
y
Static IP Address (1483 Bridged IP LLC, 1483 Bridged IP VC Mux, 1483 Routed IP LLC (IPoA), or 1483 Routed IP VC-Mux)
y
Dynamic IP Address (1483 Bridged IP LLC or 1483 Bridged IP VC-Mux)
Modulation Type
ADSL uses various standardized modulation techniques to transmit data over the allotted signal frequencies. Some users may need to change the type of modulation
used for their service. The default DSL modulation (Auto Synch-Up) used for the Router automatically detects all types of ADSL, ADSL2 and ADSL2+ modulation.
Security Protocol
This is the method your ADSL service provider will use to verify your Username and Password when you log on to their network. Your Router supports the PAP and
CHAP protocols.
VPI
Most users will not be required to change this setting. The Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI) to identify the data
path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to configure
the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can be changed in the WAN Settings window of the Web
management interface.
VCI
Most users will not be required to change this setting. The Virtual Channel Identifier (VCI) is used in conjunction with the VPI to identify the data path between your
ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to configure the VPI and VCI as
instructed by your ADSL service provider for the additional connections. This setting can be changed in the WAN Settings window of the Web management interface.

admin
.” The user may change this.
LAN IP addresses for the Router
This is the IP address you will enter into the Address field of your Web browser to access the Router’s configuration graphical user interface (GUI) using a Web
browser. The default IP address is
192.168.1.1
. This may be changed to suit any IP address scheme the user desires. This address will be the base IP address used
for DHCP service on the LAN when DHCP is enabled.
LAN Subnet Mask for the Router
This is the subnet mask used by the Router and will be used throughout your LAN. The default subnet mask is
255.255.255.0
. This can be changed later.
Information you will need about your LAN or computer
Ethernet NIC
If your computer has an Ethernet NIC, you can connect the Router to the Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the Router
to connect to other computers or Ethernet devices.
DHCP Client status
Your Router is configured, by default, to be a DHCP server. This means that it can assign an IP address, subnet mask and a default gateway address to computers
on your LAN. The default range of IP addresses the Router will assign are from
192.168.1.2
to
192.168.1.254
. Your computer (or computers) needs to be configured
to obtain an IP address automatically (that is, they need to be configured as DHCP clients.)
It is recommended that you collect and record this information here, or in some other secure place, in case you have to re-configure your ADSL connection in the future.
Once you have the above information, you are ready to set up and configure your Router.

Chapter 2 - Installation
Device Installation
The Router maintains three separate physical interfaces, an ADSL, an Ethernet, and a wireless Interface. Place the Router in a location where it can be easily
connected to Ethernet devices, the telephone line, and a power source. The Router should not be located where it will be exposed to moisture or excessive heat.
Make sure the cables and power cord are placed safely out of the way so they do not create a tripping hazard. As with any electrical appliance, observe common
sense safety procedures.
The Router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front if you need to view them for troubleshooting.
Power on Router
The Router must be used with the power adapter included with the device.
1.
Connect the Power Adapter to the power receptacle located on the rear panel of the Router and plug the other end of the power adapter to a wall outlet
or power strip.
2.
Depress the Power button into the on position. You should see the Power LED indicator on the front panel shine bright green to indicate the device is
powered on.
3.
If the Ethernet port is connected to a working device, check the LAN LED indicator to make sure the connection is valid. The Router will attempt to
establish the ADSL connection. If the ADSL line is connected and the Router is properly configured, this should light up after several seconds. If this is
the first time you have installed the device, some settings may need to be changed before the Router can establish a connection.
Factory Reset Button
The Router may be reset to the original factory default settings by using a ballpoint or paperclip to gently push down the reset button in the following sequence:
1.
With the Router powered on (check the Power LED to make sure it lights steady green), press and hold down the reset button using a paper clip or
similar object for about 6 to 8 seconds.
2.
The Router will restart. Watch the Power LED to verify that it is restarting.
3.
When it is powered on again it is ready to be configured. The whole process takes about 30 seconds.
4.
The device settings will be restored to the factory default IP address
192.168.1.1
and the subnet mask is
255.255.255.0
, the default management Username
is “
admin
” and the default Password is “
admin
.”
Note
: A factory reset will erase the current configuration settings and reset them to the default settings. After it has restarted, log in to the router’s
Web-based management interface and use the Setup Wizard to configure the basic settings.

Network Connections
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL port (RJ-11 receptacle)
on the rear panel of the Router and insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the
device or the instructions given to you by your service provider. The ADSL connection represents the WAN interface, the connection to the Internet. It is the physical
link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10/100 BASE-TX Ethernet port on the rear panel. Any connection to an Ethernet
concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of
operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port. Use standard twisted-pair cabling with
RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make this
connection. When connecting the Router directly to a PC or server use a normal straight-through cable. You should use a crossed cable when connecting the Router
to a normal (MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing
Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting the LAN to the Router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on the switch or hub
for another device, connect to any of the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed in a PC using the Ethernet cable provided.
Wireless Connection to Router
The Router’s embedded 802.11b/g/n wireless access point should be configured to suit the local wireless network. All 802.11b/g/n devices that associate with the
Router’s wireless access point must have the same SSID and channel. If wireless security is used, the wireless clients must be configured with the correct security
information to use the Router. More information on configuring the wireless settings is found later in this manual.
