3.1 System Requirements
◼ Broadband Internet Access Service (Cable/xDSL/Ethernetconnection)
◼ One Cable/xDSL Modem that has an RJ45 connector (not necessary if the Router is connected
directly to the Ethernet.)
◼ PCs with a working Ethernet Adapter and an Ethernet cable with RJ45connectors
◼ PC subscribers use Windows XP, Windows Vista, Windows 7/8/10, MAC OS 9 or later, or Linux, UNIX
or other platforms compatible with TCP/IP protocols
◼ The above PC is installed with a Web browser
1. The Router in the following instructions means DIR-825M.
2. It is recommended to use Internet Explorer 7.0 or above to access theRouter.
3.2 Installing the Router
Before installing the Router, make sure your PC is connected to the Internet through the broadband service
successfully at this moment. If there is any problem, please contact your local ISP. After that, please install the

Step 1. Power off your PC, Cable/xDSL Modem and theRouter.
Chapter 3.Connecting to the Router
Step 2. Locate an optimum location for the Router. The best place is usually at the center of your wireless
network.
Step 3. Connect the PC or Switch/Hub in your LAN to the LAN Ports of the Router with Ethernet cable.
Step 4. Connect the power adapter to the power socket on the Router, and the other end into an electrical
outlet. Then power on the Router.
Step 5. Power on your PC and Cable/xDSL Modem.

This chapter will show you how to configure the basic functions of your Wireless Router using Quick Setup
within minutes.
4.1 Manual Network Setup - TCP/IP Configuration
The default IP address of the Wireless 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 the web UI of the Wireless Router. In this section, we use all the
default values for description.
Whether the Wireless Router is configured via wired or wireless connection, the PC needs to be assigned an IP
address first. Before you connect the local PC to the Wireless Router via wired or wireless connection, please
configure the IP address for your PC in the following two ways first.
◼Obtaining an IP address automatically
◼Configuring the IP address manually
In the following sections, we’ll introduce how to install and configure the TCP/IP correctly in Windows 7. And the
procedures in other operating systems are similar. First, make sure your Ethernet Adapter is working, and refer
to the Ethernet adapter’s manual if needed.
4.1.1 Obtaining an IP Address Automatically
Summary:
1. Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on yourPC.
2. Then the Wireless Router built-in DHCP server will assign IP address to the PCautomatically.
If you are sure the DHCP server of Wireless Router is enabled, you can set up the TCP/IP Protocol in "Obtain
an IP address automatically" mode on your PC. And then the Wireless Router built-in DHCP server will assign
an IP address to the PC automatically.
1. Installing TCP/IP Component
1) On the Windows taskbar, click the Start button, point to Control Panel, and then click it.

4) In the prompt window shown below, double-click on the Internet Protocol Version 4(TCP/IPv4).
5) Choose Obtain an IP address automatically, and Obtain DNS server address automatically as
shown in the figure below. Then click OK to save your settings.

4.1.2 Configuring the IP Address Manually
Summary:
◼Set up the TCP/IP Protocol for your PC.
◼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 IPaddress)
If you are sure the DHCP server of Wireless Router is disabled, you can configure the IP address manually. The
IP address of your PC should be 192.168.0.xxx (the same subnet of the IP address of the Wireless Router, and
"xxx" is any number from 2 to 254), Subnet Mask is 255.255.255.0, and the Gateway is 192.168.0.1(The default
IP address of the Wireless Router)
1) Continue the settings from the last figure. Select Use the following IP address radiobutton.
2) If the LAN IP address of the Wireless Router is 192.168.0.1, enter IP address 192.168.0.x (x is from 2 to
254), and Subnet mask 255.255.255.0
3) Enter the LAN IP address of the Wireless Router (the default IP is 192.168.0.1) into the default gateway
field.
4) Select Use the following DNS server addresses radio button. In the preferred DNS Server field, you can
enter the DNS server IP address provided by your local ISP. Then click OK to save your settings.

Now, you can run the Ping command in the command prompt to verify the network connection between your
PC and the Router. Open a command prompt, and type ping 192.168.0.1, and then press Enter.
◼If the result displayed is similar to next figure, it means the connection between your PC and t he
Router has been established well.
◼If the result displayed is similar to next figure, it means the connection between your PC and t he
Router has failed.
