1.2 Application
The following diagram depicts a typical application of the AR-5381u.
Chapter 2 Installation
2.1 Hardware Setup
Follow the instructions below to complete the hardware setup.
BACK PANEL
The figure below shows the back panel of the device.
ADSL
Connect to the ADSL port with the ADSL RJ11 cable.
Ethernet (LAN) Ports
You can connect the router to up to four LAN devices using RJ45 cables. The ports
are auto-sensing MDI/X and either straight-through or crossover cable can be used.
USB Host Port (Type A)
This port can be used to connect the router to the print server.
Power ON
Press the power button to the OFF position (OUT). Connect the power adapter to the
power port. Attach the power adapter to a wall outlet or other AC source. Press the
power button to the ON position (IN). If the Power LED displays as expected then
the device is ready for setup (see section 2.2 LED Indicators).
Caution 1: If the device fails to power up, or it malfunctions, first verify that the
power cords are connected securely and then power it on again. If the
problem persists, contact technical support.
Caution 2: Before servicing or disassembling this equipment, disconnect all power
cords and telephone lines from their outlets.
Reset Button
Restore the default parameters of the device by pressing the Reset button for 10
seconds. After the device has rebooted successfully, the front panel should display
as expected (see section 2.2 LED Indicators for details).
NOTE:
If pressed down for more than 60 seconds, the AR-5381u will go into a
firmware update state (CFE boot mode). The firmware can then be
updated using an Internet browser pointed to the default IP address.
FRONT PANEL
The Wi-Fi & WPS buttons are located on the bottom-left of the front panel, as shown.
WiFi Switch
Press this button to enable/disable the wireless LAN (WLAN).
WPS Button
Press this button to begin searching for WPS clients. These clients must also enable
WPS push button mode (see
6.2.1 WPS for instructions).
10
2.2 LED Indicators
The front panel LED indicators are shown below and explained in the following table.
This information can be used to check the status of the device and its connections.

On
Device attempted to become IP connected and
failed (no DHCP response, no PPPoE
response, PPPoE authentication failed, no IP
address from IPCP, etc.).
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.
IP connected (the device has a WAN IP address from IPCP or DHCP and DSL is up
or a static IP address is configured, PPP negotiation has successfully complete – if
used – and DSL is up ) and no traffic detected. If the IP or PPPoE session is dropped
for any other reason, the light is turned off. The light will turn red when it attempts
to reconnect and DHCP or PPPoE fails.

Chapter 3 Web User Interface
This section describes how to access the device via the web user interface (WUI)
using an Internet browser such as Internet Explorer (version 5.0 and later).
3.1 Default Settings
The factory default settings of this device are summarized below.
•
•
•
•
LAN IP address: 192.168.1.1
LAN subnet mask: 255.255.255.0
Administrative access (username: root , password: 12345 )
WIFI access: enabled
Technical Note
During power on, the device initializes all settings to default values. It will then
read the configuration profile from the permanent storage section of flash memory.
The default attributes are overwritten when identical attributes with different values
are configured. The configuration profile in permanent storage can be created via
the web user interface or telnet user interface, or other management protocols.
The factory default configuration can be restored either by pushing the reset button
for more than five seconds until the power indicates LED blinking or by clicking the
Restore Default Configuration option in the Restore Settings screen.
3.2 IP Configuration
DHCP MODE
When the AR-5381u-NA2 powers up, the onboard DHCP server will switch on.
Basically, the DHCP server issues and reserves IP addresses for LAN devices, such
as your PC.
To obtain an IP address from the DCHP server, follow the steps provided below.
NOTE:
The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Select Obtain an IP address automatically as shown below.
13
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.
14
STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 192.168.1.x.
NOTE:
The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the 192.168.1.x (1
