Chapter 2. Connecting the Router
2.1 System Requirements
Broadband Internet Access Service (DSL/Cable/Ethernet)
One DSL/Cable Modem that has an RJ45 connector (which is not necessary if the Router
is connected directly to the Ethernet.)
PCs with a working Ethernet Adapter and an Ethernet cable with RJ45 connectors
TCP/IP protocol on each PC
Web browser, such as Microsoft Internet Explorer 5.0 , Netscape Navigator 6.0 or above
2.2 Installation Environment Requirements
Place the Router in a well ventilated place far from any heater or heating vent
Avoid direct irradiation of any strong light (such as sunlight)
Keep at least 2 inches (5 cm) of clear space around the Router
Operating Temperature: 0℃~40℃ (32℉ ~ 104℉ )
Operating Humidity: 10%~90%RH, Non-condensing
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 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) or Switch/Hub in your LAN to the LAN Ports of the 3G/4G Router with
Ethernet cable.
5. The 3G/4G Router supports both 3G/4G and WAN connection; so you can insert 3G/4G
USB Modem to the USB port of the Router (as shown in Figure 2-1), or connect the
DSL/Cable Modem to the WAN port of the Router (as shown in Figure 2-2). Please visit our
website http://www.tp-link.com to get the latest USB modems compatibility, and we
recommend you to check whether the modem in your hand has already been tested by us.
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.
This chapter will show you how to configure the basic functions of your 3G/4G Wireless N
Router using Quick Setup Wizard within minutes.
3.1 TCP/IP Configuration
The default IP address of the 3G/4G Wireless N Router 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.
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 192.168.0.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)
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) Then the built-in DHCP server will assign IP address for the PC.
3.2 Quick Installation Guide
Note:
If you are trying to connect to TL-MR3420 wirelessly, please refer to the label on the bottom of
the Router for the Wireless Password.
1. To access the configuration utility, open a web-browser and type in the default address

If you don't know how to choose the appropriate connection type, click the Detect button to
allow the router to automatically search your Internet connection for servers and protocols. The
connection type will be reported when an active Internet service is successfully detected by the
router. This report is for your reference only. To make sure the connection type your ISP
provides, please refer to the ISP. The various types of Internet connections that the router can
detect are as follows:
PPPoE - Connections which use PPPoE that requires a user name and password.
Dynamic IP - Connections which use dynamic IP address assignment.
Static IP - Connections which use static IP address assignment.
The router cannot detect PPTP and L2TP connections with your ISP. If your ISP uses one of
these protocols, then you must configure your connection manually.
