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.
¾ Configure the IP address manually (Recommended)
1) Set up the TCP/IP Protocol for your PC(s).
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(s).
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).
Note:
If you need instructions as to how to do this, please refer to
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, and then press Enter.

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.
