¾ Keep at least 2 inches (5 cm) of clear space around the Router ¾ Operating temperature: 0℃~40℃ (32℉~104℉) ¾ Operating Humidity: 10% ~ 90% RH (non-condensing)

2.3 Connecting the Router

Before installing the Router, please make sure your broadband service provided by your ISP is available. If there is any problem, please contact your ISP. After that, please install the Router according to the following steps. Don't forget to pull out the power plug and keep your hands dry.

1. Locate an optimum location for the Router. The best place is usually at the center of your wireless network.

2. Adjust the direction of the antenna. Normally, upright is a good direction.

3. Connect your PC and Switch/Hub in your LAN to the LAN Ports of the Router. (If you have a wireless NIC and want to have wireless connection, please skip this step.)

4. Connect the telephone line to the Line port on the Router. Or you can access the Internet and make calls at the same time by using a separate splitter to divide the data and voice. The external splitter has three ports:

• LINE: Connect to the wall jack

• PHONE: Connect to the phone sets

Chapter 3. Quick Installation Guide

This chapter will show you how to configure the basic functions of your TD-W8970N Wireless N ADSL2+ Modem Router using Quick Setup Wizard within minutes.

3.1 TCP/IP Configuration

The default IP address of the Router is 192.168.1.1. And the default Subnet Mask is

255.255.255.0. These values can be changed as you desire. In this guide, we use all the default

values for description.

Connect the local PC to the LAN ports of the Router. And then you can configure the IP address for your PC in the following two ways.

1. Configure the IP address manually

1) Set up the TCP/IP Protocol for your PC. If you need instructions as to how to do this, please refer to "Appendix B: Configuring the PC"

2) Configure the network parameters. The IP address is 192.168.1.xxx ("xxx" is any number from 2 to 254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.1.1 (The Router's default IP address).

2. Obtain an IP address automatically

1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on your PC. If you need instructions as to how to do this, please refer to "Appendix B: Configuring the

PC"._Appendix_B:_Configuring_the PCs

2) Then the built-in DHCP server will assign IP address for the PC.

Now, you can run the Ping command in the command prompt to verify the network connection between your PC and the Router. The following example is in Windows XP OS.

Open a command prompt, and type ping 192.168.1.1, and then press Enter.

3. If the result displayed is similar to the Figure 3-1, it means the connection between your PC and the Router has been established well.

TD-W8970N Wireless N ADSL2+ Modem Router User Guide

Figure 3-1 Success result of Ping command

¾ If the result displayed is similar to the Figure 3-2, it means the connection between your PC

and the Router is failed.

Figure 3-2 Failure result of Ping command

Please check the connection following these steps:

1. Is the connection between your PC and the Router correct?

Note:

)

The 1/2/3/4 LEDs of LAN ports which you link to on the Router and LEDs on your PC's adapter should be lit.

2. Is the TCP/IP configuration for your PC correct?

)

If the Router's IP address is 192.168.1.1, your PC's IP address must be within the range of

192.168.1.2 ~ 192.168.1.254.

Note:

TD-W8970N Wireless N ADSL2+ Modem Router User Guide

3.2 Quick Installation Guide
