Share Internet access using Wireless Self-Network

In this Internet already penetrates every corner, GUCAS’s network access charge is very uncomfortable: (more than two grades) 25 yuan per month, including 5G domestic traffic, 2G international traffic, domestic traffic exceeding part 10 yuan / g charge, the international exceeded part of the 1 yuan / m charge. Fortunately, IPv6 BT (IPv6 traffic is not included in the charging traffic), otherwise the GUCAS’s network is a tragedy.

For senior students, it is a little better. Some laboratory will have a free network, and you can slightly consider traffic distress. But if you don’t look at the BT, you don’t look at the video, if you don’t chat, 5G is not used every month, and the price of 25 yuan is not cheap, so many senior students are all in the dormitory to share an online account.

There are several ways to share online accounts: 1> Using routers, this is a relatively simple way, but this is unable to use IPv6 – current routers generally do not support IPv6 routing features, so requiring special configurations to support IPv6; 2 > Using the agent, one computer is used as the host, open an agent for another computer, in which IPv6 can be used, but the disadvantage is that the host allocated IP may change, you need to manually update the agent address, and some software does not perfect support for the agency .

I have tried another way, using wireless self-network sharing Internet access, only applicable to computer sharing Internet access on two wireless network cards. For a simple point, it is to let the two computer wireless network cards are connected, one of which (host) enters the wired Internet access to another (slave). This approach is also suitable for families with two notebooks in those homes, saving money to buy routers.

Note: The following uses the operating system platform for Windows XP SP3.

First, you need to set the wired connection of the host to be shared. The specific method is to right-click “local connection” on the host, select “Properties”, enter the “Advanced” tab, “Select Internet Connect Sharing” two check boxes, ie “Allow other network users to pass this computer Internet connection to connect “and” Allow other network users to control or disable shared Internet connectivity. “

Second, two computers are wirelessly self-assembled. The establishment of wireless self-networking network is based on different methods of network card management software. It is simple to establish a wireless connection between a point-to-point (no access point) between two notebooks. A typical configuration is:

Sign In Host: Ethernet Adapter Wi-Fi: IP address…………………………………………. Default gateway……………………………………………………………… 255.255.255.0Default Gateway……………………………………………

It should be noted that the two computers need to be in the same Windows Working Group, and the working groups of two computers here are MSHome.

If it is not very understandable to wireless self-networking, the above two steps can be set by software. Lenovo has a software called “Flash”, configured relatively easy to use, use its “shared network” function to do more. But the flash is free to have some bugs, which will cause the service to occupy the CPU too high. Once the configuration is successful, remember the establishment point-to-point network SSID (generally in Pan_ start), and then each two computers can be connected to the network. It is no longer necessary to run anything to run.

Finally, disable the IPv4 function of the slave wired interface to disable the IPv6 function of the slave wireless interface. The specific method is to right-click “local connection” on the slave, select “Properties”, “This connection uses the” Internet Protocol (TCP / IP) “before the” Internet Protocol (TCP / IP) “in the” General “selection box When the box is removed, determine exit; right-click “Wireless Network Connection” on the slave (or other name), find “Microsoft TCP / IP version 6” similar to the above location, remove the front check box.

After three steps, you can ensure that the traffic of the slave IPv4 will take the wireless interface, use the host shared IPv4 Internet access; the IPv6 traffic will take a wired interface, using the local switch’s IPv6 Internet access. Access.The second step-to-point network will be saved in the wireless network configuration, and the two computers are turned on as long as they open the wireless, and they will generally be automatically connected to the point-to-click network without having to make additional manual modifications.(Even if you use the agent’s classmates, because the wireless IP does not change, this can also bring the benefits of modifying the agent address.) In summary, this approach can perfectly realize shared IPv4 access without affecting IPv6 connections..
