To build a local area network without routers

As long as more than 2 have a network card host can achieve direct connection, for Soho or home with more than 2 notebook computers, can also break through the cable limit, through a reasonable setting in the absence of routers in the case of the establishment of a local area network.

If you do not have a wireless router, a notebook with a wireless network card can also be used to build a local area network.

Now, more and more users use notebook, in order to facilitate the user mobile office, at any time to surf the internet, some families or units are using wireless routers to set up a wireless network, to provide a convenient notebook Internet. But in the absence of wireless network environment, the wireless function of the notebook is useless. But did you ever think about it? Using the wireless network card of notebook computer to set up a wireless LAN in the dormitory? This can not only share the Internet, but also to achieve the file sharing between the computers.

Small Knowledge: Point-to-Point wireless Internet access

Wireless internet, also known as Point-to-Point Automatic Group network. Such a network through the software to achieve the wireless network card Point-to-Point (Peer-to-peer) or point-to-point (Peer-to-multi Peer) Ad-hoc Network, in which the wireless network card will automatically search for other wireless devices, and then automatically rapid connection and networking. Point-to-Point Ad-hoc Network, is also a simple LAN, users can achieve resource sharing, file transmission, game PK, share the Internet and other functions.

To understand the principle of point-to-point wireless networks, we can start networking. In fact, the AD-HOC network setup process is not difficult, we can use Windows XP with the Wireless Setup Wizard to achieve wireless interconnection.

When you use the Wireless Setup Wizard to implement the wireless internet

Setting, you first set up one of the Ad-hoc network's laptops as a host, and make sure that the computer is properly connected through "local Area Connection" or "dial-up access".

1. When you turn on the point-to-point mode of the wireless network adapter

Setting, we first enter the wireless network connection properties interface to the wireless card.

In the interface, click the Advanced button in the lower-right corner to open the Advanced options interface and select "Computer to computer only" in the "Network to access" option. This setting is very important, through this setting we will open the wireless card point-to-point interconnection function.

2. After setting the network flag

to turn on the point-to-point feature of the wireless network, we will also add a service Set flag (SSID) to the wireless network so that other notebooks can search the wireless network of that computer through the Wi-Fi. If you do not want to encrypt the network, you can set the password in the data encryption key to"Disabled." Next, we will also specify an IP address and subnet mask for this host. After the

host is set up, other computers we simply set the wireless network adapter to either "any available network" or "computer-only to computer" in the Wireless Networks configuration interface. Other items are not operational. Client settings, in the taskbar, right-click the icon of the wireless network, select "View available wireless network", the wireless network card automatically search to just set the "SSID" flag, so that the wireless network card can connect with the host-side wireless network card successfully.

through the above settings, the wireless interconnect has been set up successfully so that users can share files within the wireless network.

3. Shared Internet Settings

Although the wireless network card couplet is successful, other computers are still unable to share the network through the wireless network card, because the host is now using a local connection to the Internet, we have a dial-up connection in the host or local connection to share settings, Another computer can surf the internet via a wireless network.

After the above settings, point-to-point Internet has been built successfully, although there is no router, we can still use the LAN file transfer, sharing the Internet and other functions.
