How to use a router to set a LAN (1)

This article describes how to set up a LAN for a vro, and sets up a LAN for sharing resources among other virtual servers.

How to Use the router to set the LAN, our colleagues are using the TP-LINK router to share a network cable to access the Internet, I heard that the virtual server can be used to achieve resource sharing, but XD is a bird, I do not know where to start, thank you for your advice.

In a home or small office, if there are two or more computers, they naturally want to form a network. For convenience, the following conventions refer to it as LAN. In a home environment, you can use this network to share resources, play games that require multiplayer participation, and share a modem to enjoy Internet connections. In the office room, the use of such a network mainly solves shared peripherals such as printers. In addition, the office LAN is also an infrastructure for collaborative work by multiple people.

Looking at such a small network project, in the past, we also needed professionals to configure the network. At that time, most of the operations were manual, and general users did not have the relevant knowledge and experience. It is the case of "being inferior", which naturally limits its development. The appearance of Windows XP breaks this situation, depending on the powerful network support function and convenient wizard built in it. After the user completes the physical connection, run the Connection Wizard to test the network hardware, install the corresponding driver or protocol, and instruct the user to complete all the configuration steps.

This article introduces two networking solutions for Windows XP, and introduces the features of Windows XP in LAN.

I. Objectives:

Make up a LAN: you can connect to the Internet and allow all computers in the LAN to share the connection. You can share network resources and devices.

2. What network type is used?

Computers in the home network may have desktop or notebook machines, such as handheld computers or laptops, and may also have interfaces for various transmission media. Therefore, wired networks should not be used in the network form, wireless interfaces must be considered. However, if it can be clearly positioned on a purely wired network, there can also be no wireless interfaces. Therefore, two solutions are provided:

1. wired and wireless hybrid.

2. wired.

3. network hardware selection

Network Adapter Nic) the cards that use PCI, PC, or PCMCIA interfaces are usually used on portable or laptop computers. Windows XP also supports network adapters with USB interfaces. Whether the adapter is used depends on the computer in the access network. Regardless of the type of adapter, you need to pay attention to the coordination with the existing computer interface and HUB, the USB interface adapter may be more adaptable, but for older computers, note whether the USB interface is supported.

Network connection lines are commonly used with coaxial cables and twisted pair wires. This is something that everyone is familiar. It depends on what you think.

4. Available Network Structures and media

Ethernet structure: this structure is the most popular among office and commercial users. Many people are familiar with it, and technical materials and maintenance personnel are easy to find.

Telephone line connection: the main characteristic of this form is that the cost is very low, physical connection is also very simple, suitable for most home users.

Radio waves: electromagnetic wave signals are used to transmit signals, which can be used for communication without any connections. However, if you need to install a wireless adapter on each computer, the cost is high. In China, wireless communication is rarely used in computer networks. In the United States, a standard protocol for wireless networks, known as IEEE 802.11b, is used for computer short-distance network communication. With the support of this protocol, the network speed is 11 Mbps.

5. One of the solutions

This is a wired and wireless hybrid solution. For the detailed structure, see Figure 1. In this example, four computers form a hybrid network. PC1 is a host and has three external connections:

1. MODEM connected to the Internet: used for Internet access sharing among all computers in the network.

2. Wireless Adapter: used for communication with wireless devices in the local network.

3. HUB: Used to "Drive" downstream computers in the network.

In this solution, the PC1 and PC2 machines must use Windows XP, And the wired part uses an Ethernet connection. In the figure, HPNA is the abbreviation of home phoneline network adaptor, indicating the home telephone line network adapter. The PC3 and mobile computers in the figure do not require that the Windows XP operating system is not supported. The network connection between the mobile computer and the host uses the wireless form.

If you want to build a hybrid network, this solution already has a typical feature and can expand the network scale without a large cost.
