Chapter 2. Connecting the Router

2.1 System Requirements

¾ Broadband Internet Access Service (DSL/Cable/Ethernet)

¾ One DSL/Cable modem that has an RJ45 connector (you do not need it if you connect the

router to the Ethernet)

¾ Each PC in the LAN needs a working Ethernet Adapter and an Ethernet cable with RJ45

connectors

¾ TCP/IP protocol must be installed on each PC

¾ Web browser, such as Microsoft Internet Explorer 5.0 or later, Netscape Navigator 6.0 or later

2.2 Installation Environment Requirements

¾ Do not place in direct sunlight or near a heater or heating vent

¾ Do not cluttered or crowded. There should be at least 2 inches (5 cm) of clear space on all

sides of the router

¾ Well ventilated (especially if it is in a closet)

¾ Operating Humidity: 10%~90%RH, Non-condensing

2.3 Connecting the Router

Before you install the router, you should connect your PC to the Internet through your broadband

service successfully. 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. Power off your PC, Cable/DSL Modem, and the router.

2. Locate an optimum location for the router. The best place is usually near the center of the

area in which your PC will connect wirelessly. The place must accord with the

Installation

Environment Requirements.

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

4. Connect the PC(s) and each Switch/Hub in your LAN to the LAN Ports on the router, shown

in Figure 2-1. (If you have the wireless NIC and want to use wireless function, you can

skip

this step.)

5. Connect the DSL/Cable Modem to the WAN port on the router, shown in Figure 2-1.

6. Connect the AC power adapter to the AC power socket on the router, and the other end into

an electrical outlet. The router will start to work automatically.

7. Power on your PC and Cable/DSL Modem.

Chapter 3. Quick Installation Guide

After connecting the TL-WR542G Router into your network, you should configure it. This chapter

describes how to configure the basic functions of your TL-WR542G Wireless Router. These

procedures only take you a few minutes. You can access the Internet via the router immediately

after successfully configuring.

3.1 TCP/IP configuration

The default IP address of the TL-WR542G 54Mbps Wireless Router is 192.168.1.1. And the

default Subnet Mask is 255.255.255.0. These values can be seen from the LAN. They can be

changed as you desire, as an example we use the default values for description in this guide.

Connect the local PC to the LAN ports of the router. There are then two ways to configure the IP

address for your PC.

¾ 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 from 2 to

254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.1.1 (The router's default

IP address)

¾ 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."

2) Power off the router and PC. Then turn on the router and restart the PC. The built-in

DHCP server will assign IP address for the PC.

)

Note:

For Windows 98 OS or earlier, the PC and router may need to be restarted.

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 2000 OS.

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

If the result displayed is similar to that shown in Figure 3-1, the connection between your

PC and

the router has been established.

Figure 3-1 Success result of Ping command

If the result displayed is similar to that shown in Figure 3-2, it means that your PC has not

connected to the router.

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 port 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?

)

Note:

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, the gateway must be 192.168.1.1.

3.2 Quick Installation Guide

With a Web-based (Internet Explorer or Netscape

®

Navigator) utility, it is easy to configure and

manage the TL-WR542G 54Mbps Wireless Router. The Web-based utility can be used on any

Windows, Macintosh or UNIX OS with a Web browser.

Connect to the router by typing http://192.168.1.1 in the address field of Web browser.

Figure 3-3 Login the router

After a moment, a login window will appear similar to that shown in Figure 3-4. Enter admin for

the User Na

me and Password, both in lower case letters. Then click the OK button or press the

Enter key.
