From scratch: ADSL Broadband Internet sharing literacy class

From scratch: ADSL Broadband Internet sharing literacy class. For many friends, ADSL Broadband Internet sharing is still a common term. What does it do? What is its role? Let's take a look at these questions.

Purchase of ADSL Broadband Internet sharing products:

After determining the networking solution, enthusiastic Network Management pulled a list of products to be purchased for them. To set up such a type of wired LAN, network cables, crystal headers, connection modules, and panels are generally required. If two machines are interconnected, we need three NICs, two for the host and one for the shared machine.

To use a Broadband Router for networking, you need to buy a Broadband Router on the market. The Broadband Router on the market has four WAN ports, and the cheapest is less than one hundred yuan. If you want to share more than four machines, you can also choose eight Broadband Router products. Here, they choose to use a Broadband Router to build a shared network, all using the motherboard integrated network card, so you do not need to buy a network card.

ADSL Broadband shared Internet twisted pair wires:

As a neural network of a star topology, twisted pair wires are essential. At present, there are many different brands of twisted pair wires on the market, and the quality is also uneven. There are three types of twisted pair wires, five cat-5e twisted pair wires, and six cat-5e twisted pair wires by category. The three types of wires are used to transmit voice signals, no need to consider, and cat6 twisted pair is suitable for Gigabit Ethernet, and the hardness is high, it is difficult to install, so usually select cat5e unshielded twisted pair.

We can choose some well-known brands, such as AMP and AVAYA. The length of the twisted pair depends on the specific environment. Here we need three connection cables, which can be calculated as follows: the length of the three jumpers + 30 cm wall line length + 200 cm redundancy, this redundant line is optional to prevent line problems or change the machine location need to add twisted pair wires.

ADSL Broadband Internet sharing crystal head:

The term of the crystal head is RJ45 connector, which is used to connect the two ends of the twisted pair. You can choose some products with relatively hard materials when selecting the connector. A better crystal head is a piece of money, because the network is built on a Broadband Router, three network cables are enough. 6 crystal headers are needed. Because they are not very familiar with cabling, they also bought several more crystal heads.

ADSL Broadband shared Internet connection module:

The connection module refers to the RJ45 socket installed in the panel to connect the two ends of the Jumper. Such products are used to connect the two ends of the network cable for the purpose of line relay. The connection modules on the market are priced from RMB 20 to RMB 100 Based on the brand and product type. You can buy two cables here. There is no need for more, because the connection module can connect the cables repeatedly.

ADSL Broadband Internet sharing information panel:

The information panel is a wall that can be inserted into the RJ45 module. Generally, there are single port, dual port, and four ports on the market. Here they both save more money, I just bought two three-in-one panels that can connect telephone lines, network cables, and cable TV lines. While sharing the network, I used a cable TV line and the two watched cable TV at the same time, the cost will be greatly reduced.

When installing the panel, we can choose the installation of the hidden box and the installation of the clear box. The installation of the hidden box refers to the installation of the Panel box in the wall, which looks more elegant and generous, but the installation box must be located in the wall. The installation of the clear box refers to the installation of the Panel box outside the wall, which is easy to maintain and does not need to open too large holes in the wall.

ADSL Broadband Internet shared-bandwidth Router

Broadband routers are a popular product in Home Networking. These products provide the gateway sharing Function for LAN computers. Home broadband routers are generally equipped with four LAN interfaces and one WAN interface, the LAN interface is used to connect to the LAN Computer, while the WAN interface is used to connect to the broadband line provided by the ISP.

At present, the price of the Broadband Router on the market varies according to the configuration, from 90 yuan to 400 yuan. In Xiaohui and xiaobin's home, each of his home has only one computer, so I usually buy about yuan to meet the demand. Here they are recommended by dealers, select a TL-R402M Broadband Router product for TP-Link.

ADSL Broadband Internet sharing construction phase:

After the materials were purchased, the two men rushed to the business office to apply for the ADSL line. A few days later, the Netcom staff came to the door to install a phone number for them and activated the ADSL. Because the networking plan was generated before the decoration, Xiaohui and xiaobin asked the decoration master to help them build holes in the pre-designed wall position during the decoration process, when drilling holes, other readers should consider whether to use a dark box or a clear box to install the panel.

They borrowed RJ45 and module threading devices from the organization's network management, made two connection cables, and then connected the twisted pair wires in the panel to the module using the module threading device, after checking that the connection line is correct, use a screw to install the panel on the wall.

In this way, half of the network work has been completed. Next, connect the computer and debug the Broadband Router. The ADSL line is installed in Xiaohui's home, so he uses the network card of the computer connected to one end of the network cable, and the other end connects to the LAN interface of the Broadband Router, xiaobin needs to pass through the module on the panel before connecting to the Broadband Router, so two network cables are used. One connects the information module to the computer, and the other connects the LAN interface of the Broadband Router and the other end of the information module.

After confirming that the internal LAN is normal. Connect the Broadband Router to the adsl modem, log on to the Broadband Router using a browser on Xiaohui's machine, and use the Connection Wizard to enable the connection through PPPOE dialing. Finally, the IP address and gateway are set on the two machines, and both the machines of Xiaohui and xiaobin can share the internet. After these twists and turns, we finally achieved success. That night, the two were so happy that they could not sleep that they had played an all-night game.

Summary of ADSL Broadband Internet sharing:

Through this ADSL Broadband Internet sharing network, Xiaohui and xiaobin not only achieve dual-host internet sharing of ADSL Broadband lines, but also can conduct online games in the LAN, in addition, the cost of Internet access is reduced by about 800 yuan in a year. Later, they shared their cable lines, which greatly reduced the cost. What are you waiting for? Please join your neighbors to implement Internet cafes with shared bandwidth!
