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: 1234 , password: 1234)
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.
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
during 5 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 VG-8050 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.

12
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.
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<x<255) subnet with subnet
mask of 255.255.255.0. The screen should now display as shown below.

13
STEP 4: Click OK to submit these settings.
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.
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 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.

14
Click Login (or Acceso) to continue.
NOTE: The login password can be changed later (see section 4.1.7)
