TIPS: wireless Internet access without an AP (1)

To share a wireless network for Internet access, we often need to use a Wireless AP to build a wireless LAN, and then the client workstation can share the Internet through the wireless LAN; however, in some special work places or work environments, we sometimes have no Wireless AP at hand. In this case, is there no way for us to enjoy wireless Internet sharing? In fact, a simple wireless network can be built between several laptops installed with wireless NICs without the need for Wireless AP connection. Then, a laptop is set as a proxy server, then, other laptops will naturally be able to share Internet content over wireless networks.

Thoughts on wireless Internet sharing

By default, we can easily connect to the wireless LAN after we enable the wireless cidrds function in the laptop or directly Insert the wireless Nic device into the laptop, however, this automatic wireless connection function requires AP devices to transmit wireless signals to provide wireless network access services. In fact, there are no Wireless AP devices available in some special workplaces. What should we do? If we have two laptops installed with wireless network adapters, we can access the wireless network, but we need to modify the default working mode of the wireless network adapter, in order to achieve point-to-point wireless network connection.

We know that wireless network card devices usually have two working modes: AP working mode and point-to-point working mode. AP working mode is the normal working mode of wireless network, this mode requires all wireless workstations to be connected to the Wireless AP device to work. The Wireless AP device is the most important network device in the wireless LAN. If the network device is damaged, then the entire Wireless LAN network will be paralyzed automatically. A point-to-point network is a wireless network without a core and can be freely combined. It does not need to be attached to any fixed network device for work, therefore, we can use this working mode to build a flexible temporary wireless network. In a point-to-point transmission network environment, any client workstation exists as an independent body. Any failure or unexpected shutdown of a common workstation will not affect the stability of the entire wireless network.

Obviously, without Wireless AP devices, we can use point-to-point wireless working mode to build a cheap temporary Wireless LAN. Once a wireless LAN is available, in this case, we only need to install the proxy server software in one of the laptops so that it becomes a LAN proxy server, so that other laptops can share the Internet through the proxy server.

Build point-to-point Wireless Networks

This document uses two laptops as an example to describe how to set up a point-to-point wireless network. Assume that one laptop is a and the other is B. Now we can set the working mode of the wireless Nic device as follows:

First, install the wireless network card device to computer a correctly. Then, the computer automatically runs the built-in wireless signal search program, because the wireless Nic device works in AP mode by default, if there is a wireless router or Wireless AP around the laptop, this signal search program can search for wireless Internet access signals sent from Wireless AP devices, so that computer A can easily access the specified Wireless LAN in AP working mode; because there is no Wireless AP device near computer A, the wireless signal search program in the computer cannot find the wireless network, and the prompt message shown in 1 is displayed;

Click Start, set, and network connection commands. In the displayed local network connection List window, find the network connection icon corresponding to the wireless network card device, right-click the network connection icon and execute the "properties" command from the shortcut menu to open the attribute setting window for the target wireless network connection;
