3.1 System Requirements
 Broadband Internet Access Service (Cable/xDSL/Ethernet connection)
 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 RJ45 connectors
 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 the Router.
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
Router according to the following steps. Don't forget to pull out the power plug and keep your hands dry.
Step 1. Power off your PC, Cable/xDSL Modem and the Router.

Step 2. Locate an optimum location for the Router. The best place is usually at the center of your wireless
network.
St
ep 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

This chapter will show you how to configure the basic functions of your Wireless Router using Quick Setup
within minutes.
A computer with wired Ethernet connection to the Wireless Router is required for the first-
time configuration.
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 your PC.
