2.3 Connecting the Router
Before installing the router, make sure your PC is connected to the Internet through the
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 at the center of your
wireless network. 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 the wireless function, you can skip
this step.)
5. Connect the DSL/Cable Modem to the WAN port on the router, shown in Figure 2-1.
6. Connect the power adapter to the power socket on the router, and the other end into an
electrical outlet. The router will start to work automatically.

Chapter 3. Quick Installation Guide
This chapter will show you how to configure the basic functions of your TL-WR941ND 300Mbps
Wireless N Router using Quick Setup Wizard within minutes.
3.1 TCP/IP Configuration
The default domain name of the TL-WR941ND 300Mbps Wireless N Router is
http://tplinklogin.net, the default IP address is 192.168.0.1, and the default Subnet Mask is
255.255.255.0. These values can be changed as you desire. In this guide, we use all the default
values for description.
Connect the local PC to the LAN ports of the router. And then you can configure the IP address for
your PC in the following two ways.
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 192.168.0.xxx ("xxx" is any number
from 2 to 254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.0.1 (The router's
default IP address)
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.
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 XP.
Open a command prompt, and type ping 192.168.0.1, and then press Enter.
¾If the result displayed is similar to the Figure 3-1, it means the connection between your PC
and the router has been established well.

Figure 3-1 Success result of Ping command
¾If the result displayed is similar to the Figure 3-2,it means the connection between your PC
and the router is failed.
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 ports which you link to on the router and LEDs on your PC's adapter
should be lit.

300Mbps Wireless N RouterTL-WR940N/TL-WR941ND
-10-
2. Is the TCP/IP configuration for your PC correct?
)Note:
If the router's IP address is 192.168.0.1, your PC's IP address must be within the range of
192.168.0.2 ~ 192.168.0.254.
3. Is the default LAN IP of the router correct?
)Note:
If the LAN IP of the modem connected with your router is 192.168.0.x, the default LAN IP of the
router will automatically switch from 192.168.0.1 to 192.168.1.1 to avoid IP conflict. Therefore, in
order to verify the network connection between your PC and the router, you can open a command
prompt, and type ping 192.168.1.1, and then press Enter.
3.2 Quick Installation Guide
With a Web-based utility, it is easy to configure and manage the TL-WR941ND 300Mbps Wireless
N Router. The Web-based utility can be used on any Windows, Macintosh or UNIX OS with a Web
browser, such as Microsoft Internet Explorer, Mozilla Firefox or Apple Safari.
1. To access the configuration utility, open a web-browser and type in the default address
http://tplinklogin.net in the address field of the browser.
Figure 3-3 Login the Router
After a moment, a login window will appear, similar to the Figure 3-4. Enter admin for the User
Name and Password, both in lower case letters. Then click the OK button or press the Enter key.
Figure 3-4 Login Windows
)Note:
If the above screen does not pop-up, it means that your Web-browser has been set to a proxy. Go

WAN Connection Type.
3. Click Next, and then WAN Connection Type page will appear, shown in Figure 3-6.
Figure 3-6 Choose WAN Connection Type
The router provides Auto-Detect function and supports five popular ways Dynamic IP,
Static IP,PPPoE/Russian PPPoE, L2TP/Russian L2TP and PPTP/Russian PPTP to
connect to the Internet. It’s recommended that you make use of the Auto-Detect function. If
you select Auto-Detect, the router will automatically detect the connection type your ISP
provides. If you are sure of what kind of connection type your ISP provides, you can select
the very type and click Next to go on configuring.
