How to set up a broadband router

This article takes the di-740p model of broadband router D-link, the default management address is 192.168.0.1, and the management port is 8080.

Set the IP address and router management address of a computer to the same network segment, such as 192.168.0.2, open the browser of 192.168.0.2 computer, enter "http://192.168.0.1:8080" in the Address bar and press ENTER to appear the user Login prompt window, Enter the default admin account and password in the broadband router specification to enter the settings interface.

In order for the router to dial automatically, we also need to integrate the ADSL account into the router.

Click on the top of the "Home" tab, and then click on the Change "WAN", in the PPP over Ethernet see the setting of ADSL account, enter their own application for ADSL account and password save settings.

Now go to the System Information section in the System Status tab to view the networking status, where you can see clearly the network information that ADSL dial-up obtains on the WAN side.

After setting up the ADSL account, we can access the Internet through the broadband router, but in order to better manage and improve security, we need to do the following: Click "Home" tab, then select "DHCP" on the left, and set the IP address range at the IP range where the DHCP server can enter, After saving, the broadband router has the function of automatically assigning IP address.

To prevent the chaos of BT

Default settings All computers connected to the router are protected, that is, in the intranet, the use of Peer-to-peer software such as BT will be affected. We can set the declared host by using the "DMZ" in the "Advanced Settings" tab. Set up here the host is exposed to the network, on the one hand can use BT download software and establish IIS, FTP server, and on the other hand also exposed to hackers and viruses, so this computer security work must be done well. (if only to use BT and other Peer-to-peer software and the host to announce the words is very unwise, in fact, we can use UPnP function to solve the intranet can not use Peer-to-peer software problems. Click "Other Items" under the "Tools" tab of the Router settings interface, and then set UPnP to "start". ）

Enter the Filter tab in the Broadband router Setup interface, we can filter the source and address of the datagram, including IP address, URL information, MAC address and regional information.

Set "Activate" IP address filtering, and then enter the IP address within the IP address range, such as 192.168.0.111. "Port range" is actually filling out the information, because the BT download using 6881 to 6889 ports, so we can filter here. "Protocol" selects TCP, and "scheduling" sets the time for the filter to take effect (the time is forbidden to see the actual situation).

Both service and security

Computers exposed to the Internet hackers and viruses may exploit vulnerabilities to attack computers, but we can solve this problem by setting up virtual servers.

Login to the broadband router Setup interface. Select the virtual server label in the Advanced Settings interface. To activate the virtual server settings, enter the relevant virtual server information. For example, we want to allow 192.168.0.112 this computer to provide FTP services, but also want to let other ports to be protected by the router, you can only virtual the FTP service. The personal IP address is set to 192.168.0.112, and the Protocol mode is TCP (the FTP service uses the TCP protocol) and the personal port (FTP uses 21 ports). Additionally, you can set the time period in which the virtual service takes effect.

Tp-link Router Configuration Guide

The basic configuration of the router, so that the computer through the router to share the Internet, the process is relatively easy to achieve; The following sections of this document mainly describe the following parts:

1, collect and judge the information, prepare for configuring the router;

2, enter the router management interface, configure the router;

3, configure the process of simple fault location to eliminate!

1, the preparation before the router (if you are aware of your own connection, you can skip to the 2nd)

The first thing to be sure of is what is your "broadband access" approach?

Of course, the easiest way to do this is to call your ISP (Internet service provider) for advice, or you can make a quick decision with the way you purchased your router's previous network connection.

There are several common ways to connect hardware:

1, telephone line-> ADSL modem-> Computer

2, twisted pair (Ethernet cable)-> computer

3, cable TV (coaxial cable)-> Cable modem-> Computer

4, optical fiber-> Photoelectric Converter-> proxy server-> PC

ADSL/VDSL PPPoE: A computer running a third-party dial-up software such as Enternet300 or WinXP system with its own dialer, fill in the account and password provided by the ISP, each time before the Internet to dial;

Or your ADSL MODEM has enabled the routing function, fills in the ISP to provide the account number and the password, the dialing movement gives the MODEM to do; (this kind of broadband access mode is typical such as the "Network Express" provided by Southern Telecom)

Static IP:ISP provides you with fixed IP address, subnet mask, default gateway, DNS;

Dynamic IP: The computer's TCP/IP property is set to "Automatically obtain IP address", each time you start the computer can access the Internet; (this kind of broadband access mode typical such as Shenzhen "Tianwei video")

802.1x+ static IP:ISP provides fixed IP address, special dialing software, account number and password;

802.1x+ Dynamic IP:ISP provides special dialing software, account number and password;

Web authentication: Every time before the Internet, open IE browser, first go to the ISP designated home page, fill in the user name provided by the ISP password, through the certification before you can do other online operation;

(The bold text above is your broadband access mode, the access mode and the hardware connection is not a fixed collocation)

These connection authentication methods mentioned above are only some broadband access methods with high penetration rate, of course there are other topological connections and authentication methods exist; So when you are not sure of your broadband approach, it is best to ask the ISP: their installed broadband access, IP address is static or dynamic? Is the protocol used for authentication PPPoE, 802.1X or Web authenticated? When the above two problems have the answer, you can configure the router;

2, how to enter the Router management interface?

The first reference to the "User manual" above the icon, the ADSL MODEM, routers, computers link up;

TL-R4XX Series Router's management address factory defaults: IP Address: 192. 168.1. 1, subnet mask: 255. 255.255. 0 (tl-r400 and tl-r400+ two admin address defaults to: 192. 168.123. 254, Subnet mask: 255. 255.255. 0 the router LAN port and computer network card connection is good, because the Ethernet port on the router has the polarity of automatic flip function, so no matter your network cable using straight line or crossed lines can be, you need to ensure that the production of the crystal head of a reliable and stable, crystal Head copper film does not rust.

On the desktop, right-click on "My Network Neighborhood", select "Properties", double-click Open "Local Connection" in the pop-up window, click "Properties" in the pop-up window, then look for Internet Protocol (TCP/IP), and double-click the Internet Protocol (TCP/IP) Properties window;

Select "Use the following IP address" in this window and fill in the corresponding location:

IP Address: 192. 168.1. X (x range 2-254),

Subnet Mask: 255. 255.255. 0,

Default gateway: 192. 168.1. 1, after filling out "OK" two times;

3, check the computer and the router can communicate?

The following methods can be used to view, open the computer's DOS interface:

"Start"-> "program", click "MS-DOS" (Win98 operating system)

"Start"-> "Programs"-"Accessories", click "Command Prompt" (WIN2000/XP operating system)

First, check the above IP address configuration is effective?

In DOS window input: Ipconfig/all and enter, when you see a message similar to the following to indicate that the configuration is in effect,

IP Address .................................. : 192. 168.1. 10

Subnet Mast ..............: 255.......... 255.255. 0

Default Gateway. ............................ . : 192. 168.1. 1
