How to build a LAN without using a wireless router

With the development of China's routing industry, it also promotes the wide application of wireless routers. Here we mainly analyze how to build a LAN without using wireless routers, see the title, are you surprised? In fact, you can directly connect to more than two hosts with NICs. When soho or home has more than two laptops, you can also break through the cable restrictions, you can set up a LAN when using a wireless router. If you do not have a wireless router, you can use a laptop with a wireless Nic to build a LAN.

Now, more and more users are using laptops. To make it easier for users to move their offices and access the Internet at any time, some families or organizations use wireless routers to build a wireless network, which provides convenience for laptops to access the Internet. However, in an environment without a wireless network, the wireless functions of the notebook become useless. But have you ever thought about creating a wireless LAN in the dormitory using the laptop wireless network card interconnection function? This not only enables Internet sharing, but also enables file sharing between computers.

Knowledge: point-to-point Wireless Networks

A wireless Interconnected Network, also known as point-to-point automatic networking. Such a network implements a Peer-to-Peer or Peer-to-Multi-Peer Ad-Hoc network through software, in this network, the wireless network adapter will automatically search for other wireless devices, and then automatically perform fast connection and networking. A point-to-point Ad-Hoc network is also a simple lan. Users can share resources, file transfers, game PK, Internet sharing, and other functions. After learning about the principles of point-to-point wireless networks, we can establish a network. In fact, it is not difficult to set up the Ad-Hoc network. We can use the wireless setting Wizard provided by Windows XP to achieve wireless interconnection. When you use the wireless setup wizard to set up wireless interconnection, you must first set up a laptop in the Ad-Hoc network as the host, make sure that the computer accesses the Internet through "Local Connection" or "dial-up Internet.

1. Enable the point-to-point mode of the wireless network card

When setting, we first go to the "Wireless Network Connection Properties" interface of the wireless network card. On this page, click the "advanced" button in the lower-right corner to open the "advanced options" interface, and click "computer to computer only" in the "Network to be accessed" option ". This setting is very important. Through this setting, we enable the point-to-point interconnection function of the wireless network card.

2. Set network flag

After enabling the point-to-point feature of the wireless network, we also need to add a Service Identifier (SSID) for the wireless network so that other laptops can search for the wireless network of the computer through the wireless network card. If you do not want to encrypt the network, you can set the password mode to "disabled" in "Data Encryption ". Next, we need to specify an IP address and subnet mask for the host.

After the host is set, you only need to set the wireless network adapter to any available network or computer-only mode on the "wireless network configuration" page for other computers. You do not need to perform other operations. After setting the client, right-click the Wireless Network icon in the taskbar and select "view available wireless networks". The wireless network adapter will automatically find the configured "SSID, in this way, the wireless network card can be connected to the wireless network card of the host. Through the above settings, the wireless network has been set up successfully, so that users can share files in the wireless network.

3. Internet sharing settings

Although the wireless network card is successfully connected, other computers still cannot share the network through the wireless network card, because the host currently uses a local connection to access the Internet, after we share the dial-up connection or local connection in the host, the other computer can access the Internet through wireless networks. After the above settings, the point-to-point interconnection network has been established successfully. Although there is no wireless router, we can still use the file transmission and Internet sharing functions in the LAN.
