Chapter 1 Introduction

The CT-5374 Multi-DSL WLAN Router provides wired and wireless access for
high-bandwidth applications in the home or office. It includes four fast Ethernet
ports and supports ADSL2/2+ and VDSL2 connections
ADSL2+ connections support multiple simultaneous Internet connections while
VDSL2 connections are suitable for triple play (Video + Voice + Data) applications.

An integrated 802.11n (draft) WLAN Access Point (AP) provides faster wireless
connections with increased range, when compared with 802.11b and 802.11g,
without sacrificing backwards compatibility with these older wireless standards.
WPS (Wi-Fi Protected Setup) and Wi-Fi On/Off buttons are positioned on the front
panel for easy wireless network setup and control.

Ethernet (LAN) Ports

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.

A/VDSL Port

Power Button

Power Port

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 5 to
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 20 seconds, the CT-5374 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.

7

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.

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.

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).

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.

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.
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 CT-5374 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.

11

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<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.

13

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

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

http://192.168.1.1.

3.1 Default Settings.

Click OK to continue.

NOTE: The login password can be changed later (see

14

8.6.1 Passwords).
