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 Ether net 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

Chapter 3. Quick Installation Guide 
After connecting the TL-WR542G Router into your network, you should confi gure it. This chapter 
describes how to configure t he 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 255.255.25 5.0. These values can be seen from the LAN. They can be 
changed as you desire, as an exam ple we use the default values for description in this guide. 
Connect the local PC to the LAN ports of the rout er. 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 Gatewa y is 192.168.1.1 (The routers 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 connecti on 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 bet ween 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 PCs adapter 
should be lit. 
2.  Is the TCP/IP configur ation for your PC correct?

) Note: 
If the routers IP address is  192.168.1.1, your PCs IP addre ss 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
