Chapter 1 Introduction
The VR-3031u is an 802.11n compliant Multi-DSL router that supports both ADSL2+ and
VDSL2. The latter is a brand new standard and technology perfect for triple play (Video,
Voice and Data) applications. The VR-3031u comes with four 10/100 Base-T Ethernet
ports, and one USB host, combining wired LAN connectivity and an integrated 802.11n
WiFi WLAN Access Point (AP) for wireless connectivity.
The VR-3031u is a cost effective solution designed to meet the needs of ISPs and carriers
planning on deploying a single DSL device for covering end users in different loop range areas.
Deploying VR-3031u is cost effective for ISPs and carriers because deploying a single CPE
DSL device with multiple profile support minimizes the number of required upgrades.
Chapter 2 Installation
2.1 Hardware Setup
Follow the instructions below to complete the hardware setup.
Non-stackable
This device is not stackable – do not place units on top of each other, otherwise
damage could occur.
BACK PANEL
The figure below shows the back panel of the device.
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 VR-3031u 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.
WPS/WiFi Button
Press and release WPS-WiFi button to activate WPS (make sure the WPS is enabled
in Wireless->Security page).
Press and hold WPS-WIFI button more than 5 seconds to enable/disable WiFi.
Ethernet (LAN) Ports
Use 10/100 BASE-T RJ-45 cables to connect up to four network devices. These ports
are auto-sensing MDI/X; so 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.
DSL Port
Connect to an ADSL2/2+ or VDSL with this RJ11 Port. This device contains a micro
filter which removes the analog phone signal. If you wish, you can connect a
regular telephone to the same line by using a POTS splitter.
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.

PPPoE session is dropped due to an idle timeout, the
light will remain green if an ADSL connection is still
present.

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.
x

x
x
x
x
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.
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 VR-3031u 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.
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.
12
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
