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 temperature: 0 ~40 (32 ~104 )℃℃℉ ℉
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.)

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
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.
