Chapter 4: Quick Installation Guide
After connecting the TL-R402M router into your network, you should configure it. This
chapter describes how to configure the basic functions of your TL-R402M Cable/DSL
Router. These procedures only take you a few minutes. You can access the Internet via
the router immediately after it has been successfully configured.
4.1 TCP/IP configuration
The default IP address of the TL-R402M Cable/DSL Router is 192.168.1.1, and the
default Subnet Mask is 255.255.255.0. These values can be seen from the LAN, and can
be changed as your desire. As an example, we use the default values for description in
this guide.
Connect the local PCs to the LAN ports on the router. There are then two means to
configure the IP address for your PCs.
Configure the IP address manually
1) Set up the TCP/IP Protocol for your PC(s). If you need instructions as to how to
do this, please refer to
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)
Obtain an IP address automatically
1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on
your PC(s). If you need instructions as to how to do this, please refer to
Appendix B: "Configuring the PCs."
2) Power off the router and PC(s). Then turn on the router, and restart the PC(s).
The built-in DHCP server will assign IP addresses for the PC(s).
Appendix B: "Configuring the PCs."
Now, you can run the Ping command in the command prompt to verify the network
connection between your PC(s) and the router. The following example is in Windows
2000.
Open a command prompt, and type ping 192.168.1.1, then press Enter.
Figure 4-1 Successful result of Ping command
If the result displayed is similar to what is shown in figure 4-1, the connection between

TL-R402M Cable/DSL Router User Guide
your PC and the router has been established.
Figure 4-2 Failed result of Ping command
If the result displayed is similar to what shown in figure 4-2, it means that your PC has
not connected to the router. If so, refer to the following steps for a solution.
1. Is the connection between your PC and the router correct?
Note: The Link/Act LEDs of LAN port 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
4.2 Quick Installation Guide
With a Web-based (Internet Explorer or Netscape® Navigator) utility, the TL-R402M
Cable/DSL Router is easy to configure and manage. 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.
