Chapter 3. 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.
3.1 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.
¾Configure 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 any
number from 2 to 254), Subnet Mask is 255.255.255.0.
¾Obtain 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) Then 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 commasnd 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.

Figure 3-1 Successful result of Ping command
If the result displayed is similar to what is shown in Figure 3-1, the connection between your PC
and the router has been established.
Figure 3-2 Failed result of Ping command
If the result displayed is similar to what shown in Figure 3-2 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.
3.2 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.

)Note:
1. If you change the IP address of the LAN, you must use the new IP address to login to the
router.
2. If the new LAN IP Address you set is not in the same subnet, the IP Address pool in the
DHCP sever will not take effect, until they are re-configured.
3. If the new LAN IP Address you set is not in the same subnet, the Virtual Server and DMZ
Host may change accordingly at the same time, you’d better re-configure it as well.
4.4.2 WAN
You can configure the WAN port parameters on this page.
First, please choose the WAN Connection Type (Dynamic IP/Static IP/PPPoE/L2TP) to the
Internet. The default type is PPPoE. If you aren’t given any login parameters (fixed IP address,
logging ID, etc), please select Dynamic IP. If you are given a fixed IP (static IP), please select
Static IP. If you are given a user name and a password, please select PPPoE. If your ISP
provides L2TP connection, please select L2TP option. If you are not sure which connection type
you use currently, please contact your ISP with the correct information.
1. If you choose Dynamic IP, the router will automatically get IP parameters from your ISP. You
