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)
 User access (username: user, password: user)
 Remote (WAN) access (username: support, password: support)
 WLAN 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.

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<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 section 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.

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 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 section 8.6.1 Accounts).
