1.2 Application
The following diagram depicts the application of the device on a wireless network.

1.3 Front Panel LED Indicators
The front panel LED indicators are shown in the picture below and followed by an
explanation in the table below.
LED Color Mode Function
Green On The router is powered up.
Off The router is powered down.
POWER
Red On POST (Power On Self Test) failure (not bootable) or
Device malfunction.
A malfunction is any error of internal sequence or state
that will prevent the device from connecting to the
DSLAM or passing customer data. This may be
identified at various times such after power on or
during operation through the use of self testing or in
operations which result in a unit state that is not
expected or should not occur.
Green On An Ethernet Link is established.
Off An Ethernet Link is not established.
LAN
4x~1x Green Blink Data transmitting or receiving over LAN.
Green On The wireless module is ready and idle.
Off The wireless module is not installed.
WLAN
Green Blink Data transmitting or receiving over WLAN.
Green On A USB link is established.
Off A USB link is not established.
USB
Green Blink Data transmitting or receiving over USB.

8
Green On DSL good sync
Off Modem power off
ADSL
Green Blink Flashing Green = DSL attempting sync
Flashing at 2 Hz with a 50% duty cycle when trying to
detect carrier signal
Flashing at 4 Hz with a 50% duty cycle when the carrier
has been detected and the modem is trying to train.
Green On IP connected and no traffic detected. If an IP or PPPoE
session is dropped due to an idle timeout, the light will
remain green if an ADSL connection is still present.
Off Modem power off, modem in bridged mode or ADSL
connection not present. Also, if an IP or PPPoE session
is dropped for any reason, other than an idle timeout,
the light is turned off.
Green Blink IP connected and IP Traffic is passing thru the device
(either direction)
INTERNET
Red On Device attempted to become IP connected and failed
(no DHCP response, no PPPoE response, PPPoE
authentication failed, no IP address from IPCP, etc.)
The light will turn red when it attempts to reconnect
and DHCP or PPPoE fails.

Chapter 2 Installation
2.1 Hardware Installation
In the rear panel, there is a reset button. To load the factory default settings, hold
the reset button down for at least 5 seconds.
Follow the instructions below to complete the hardware connections.
Connection to LINE port
If you wish to connect both the router and a telephone, connect the LINE port to a
POTS splitter with a RJ11 connection cable.
Connection to LAN port
To connect to a hub or PC, use a RJ45 cable. You can connect the router to up to four
LAN devices. The ports are auto-sensing MDI/X and either straight-through cable
or crossover cable can be used.
Connection to USB port
Connect the USB port to a PC with a standard USB cable.

10
Connection to Power
Connect the Power jack to the shipped power cord. Attach the power adapter to
the wall outlet or other AC source.
After all connections have been made, press the power-switch in to turn the device
on. After power on, the router performs a self-test. Wait for a few seconds until the
test is finished, then the router will be ready to operate.
Caution 1: If the router fails to power up, or it malfunctions, first verify that the
power supply is connected correctly. Then power it on again. If the
problem persists, contact our technical support engineers.
