• ADSL LED - 

This green LED flashes while a link is being set up on the ADSL port.

The LED stays on when the link has been set up and is functioning correctly.

• Online LED - 

This green LED will normally be off but flashes when data is sent or 

received on the ADSL port.

• WLAN LED - 

When this green LED is on, wireless networking is enabled. The LED will

flash when data is sent or received over a wireless connection.

• LAN LEDs (LAN1, LAN2, LAN3 and LAN4) - 

These green LEDs turn on when there 

is an Ethernet connection to the corresponding LAN port on the back panel and will
flash to indicate that data is being sent or received over the connection.

• Phone LED -

Shows the VoIP FXS connection status.  When the green LED is solid, 

the Phone is OFF-Hook talking on a call. When the green LED is blinking, it indicates
there is an incoming VoIP Call. When the LED is off, the phone is ON-Hook.

1. ADSL Port

- Use the supplied cable to connect the ADSL port to your phone socket.

The DSL LED on the front panel will light up when the connection is made and the 
Online LED will turn when you are able to send and receive data.

2. LAN Ports (1, 2, 3 and 4)

- There are four Ethernet LAN ports for connection to PCs, 

network printers or similar devices. Note the labelling; one LAN LED on the front panel is 
associated with one port on the rear panel. Port 1 is associated with the LAN1 LED, port 2 
with LAN2 and so on. If a device is not correctly connected, using a suitable Ethernet 
cable, the associated LED will not turn on.

3. Power

- Connect the supplied, 12V power adapter to this socket.

4. Reset

- You can restart the unit by pressing the reset button and releasing it 

immediately. If, for any reason, you need to reset the unit to factory defaults and 
cannot access the user interface (e.g. if you have changed and forgotten the 
password), press the reset button for 10 seconds. Note that you will lose all your 
configuration changes when you reset the router to factory defaults.

5. USB 1.1 Port - 

Use this port for connecting USB printer or storage device.

6. RJ-11 FXS Phone Ports -

Use these ports to connect to a telephone.

Ethernet cables

Ethernet cables are usually constructed from unscreened, “Cat 5” cable with 
RJ45 connecters at both ends. Cables of this type can be purchased at most 
computer retailers.

Installation Troubleshooting

• Check that the Power Adapter is both plugged into a working power socket and 

connected to the Router. Check that the green PWR LED on the Router is on. 
Only use the power adapter that was supplied with your Router.

• The wired PC should connect to a LAN port of the Router using an Ethernet 

cable. The corresponding LAN LED of the Router should be on.

• The Router ADSL port should be connected to your phone socket on the wall. The DSL

LED should be on when there is a valid connection to your ISP. The Online LED will 
flash when data is transferred to and from the ADSL port.

• Power up your equipment in the following order: First the ADSL Router and then 

your PC. Leave at least 30 seconds between turning on each device.

• The PC should be setup to obtain an IP address automatically from the Router's 

DHCP server. See the user manual on the CD for details of how to setup your PC 
to obtain an IP address.

• Check that web proxy is disabled on your PC. Go to the Control Paneland select 

Internet Options. Select the Connections tab and click the LAN Settings button. 
Check that the Use Proxy Serveroption is not ticked.

• Check you can access the Router's web interface. Open a browser and enter 

http://192.168.2.1

to access the default IP address of the Router.

WAN Connection Troubleshooting

• Check that you have selected the correct WAN connection option and the ISP 

details are correct. If you do not have these details, they can be obtained from 
your ISP.

• If you have any PPPoE client applications already installed on your PC which 

were required when your PC was directly connected to the DSL modem, they 
must be disabled.

Wireless Troubleshooting

• Check that the SSID is the same on the Router and the wireless PC.
• Check that the wireless encryption is the same on the Router and the wireless 

PC. To help debug a problem, turn off encryption in both the Router and wireless
PC until you can establish a connection. After a change in encryption, some PCs 
may have to be restarted.

• The wireless PCs must be set to Infrastructure mode to work with a Router.
• If your computer has both a wired and wireless connection installed, ensure that 

the wired Ethernet cable is unplugged.

• Check that the Router WLAN LED is on, to indicate that Wireless networking is 

enabled. To enable wireless networking, go to the Router Wireless page and 
enable Wireless Networking.

• If there are a number of wireless networks within range, then you may 

experience poor wireless performance if the wireless channels are too close 
together. Ideally, neighbouring wireless networks should be at least 5
channels apart. The wireless channel is controlled by and set in the Router.

• The Router has a feature called MAC Filter which controls which wireless PCs 

have access to the wireless LAN. If this feature is enabled, then ensure that the MAC 
address of your wireless PC card is listed in the MAC Filter page.
