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 ten 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-5313u 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. 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.

14
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.

15
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. 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<x<255) subnet with subnet mask of
255.255.255.0. The screen should now display as shown below.
STEP 4: Click OK to submit these settings.

16
3.3 Login Procedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in 3.1 Default Settings.
STEP 1: Start the Internet browser and enter the default IP address for the device in the Web
address field. For example, if the default IP address is 192.168.1.1, type
http://192.168.1.1.
NOTE: For local administration (i.e. LAN access), the PC running the browser must be attached
to the Ethernet, and not necessarily to the device.
For remote access (i.e. WAN), use the IP address shown on the Chapter 4 Device
Information screen and login with remote username and password.
STEP 2: A dialog box will appear, such as the one below. Enter the default username and
password, as defined in section 3.1 Default Settings.
Click OK to continue.
NOTE: The login password can be changed later (see 8.6.1 Accounts).
