Wireless Network Creation Mode content sharing

What are the establishment modes of wireless networks? We can build different networks for different hardware devices. Now let's take a look at the specific content. No vro: we still need to build a wireless network construction mode. As you know, the most basic Networking Mode of the wireless network construction mode is two. One wireless network construction mode is Infrastructure, one wireless network is set up in Ad-hoc mode. The Infrastructure mode is a wireless access mode centered on a Wireless AP or a wireless router. to access this mode, you only need to "refresh the Network List" on the Wireless Configuration Interface of Windows XP ", select the wireless access point to be connected and click "Connect" to access the Internet easily.

Ad-hoc is a network composed of terminals and servers using wireless network cards. It does not require Wireless AP or wireless routers and uses wireless network cards + wireless network cards, this allows 254 computers in the same network segment to be easily networked. Ad-hoc networks are more practical than common wired peer-to-peer networks that can only achieve dual-machine interconnection.

1. Set up an Ad-hoc Network

How can I set up an Ad-hoc peer-to-peer network for several or dozens of computers with wireless NICs? Many readers do not understand this. I will introduce it in detail below:

◆ After the driver is installed for the wireless network card, open the "wireless connection icon" in the lower-right corner of the desktop and select "change the preferred network sequence ". Enable the "wireless network construction mode" option, select "advanced", and select "computer-to-computer Ad-hoc) network" for "network to be accessed ", select the "automatically connect to a non-preferred network" check box and click "close.

◆ In the "wireless network construction mode" option, enable "add" and write "network name SSID, ServiceSetIdentifier" to ESSID to distinguish different networks, A maximum of 32 characters can be entered. Only computers with the same SSID name can communicate with each other. It is like a working group name in a wired network .)" Add a network name, such as 999. Note that the SSID name of each computer in the Ad hoc network should be set to the same, such as 999 in this example.

◆ In the "add" interface, you also need to set the key for the wireless network creation mode. For most temporary Ad-hoc networks, we recommend that you set "Data Encryption" to "disabled ". In this way, multiple computers can directly implement Ad-hoc Network Interconnection without entering the key.

Of course, if you consider security, you can also enter your own easy-to-remember key. Select an option for "network verification". Remove the check box before "automatically providing this key for me, enter the same key in "Network key" and "Confirm network key", which can be numbers and letters ). To connect other computers, you only need to enter the corresponding key in the key input prompt box.

Ii. Play "soft AP"

Some wireless network adapters have a special feature in the manufacturers' publicity, that is, they can be transformed into "soft APSoftAP, software AP )". In fact, the "soft AP" function is a function available for each wireless network card. a modem needs the corresponding interface, for example, a USB interface MODEM needs a spare USB interface, ethernet interface MODEM requires the computer to have a wired network card and Interface) + a wireless network card + a shared software, such as the built-in "Internet Connection Sharing/ICS" in Windows "), this allows the wireless network construction mode to implement "soft AP" and routing functions, and provides Internet sharing services for other computers in the WLAN Network.

◆ To implement such functions, you must first ensure that the MODEM can access the Internet on the computer selected as the server.

◆ Second, you must specify the IP address and DNS information for each computer. First, enable the wireless network creation mode attribute of the computer selected as the server. Double-click "Internet protocol TCP/IP" in the "General" option, select "Use the following IP Address", set "IP address" to 192.168.1.1, And the subnet mask is 255.255.255.0 by default. "Use the following DNS server address" to set "preferred DNS server" to the local server address provided by the ISP, for example, local 61.139.2.69, the "backup DNS server" is 202.96.128.68. The address varies by region. Contact the broadband carrier ).

◆ 3. Set the IP address for other computers. Set the IP address to the IP address range from 192.168.1.2 to 254 to ensure that the IP address varies between 2 and on each computer. The subnet mask is 255.255.255.0 by default, the gateway is 192.168.1.1. "Use the following DNS server address" to set "preferred DNS server" as the local server address provided by the ISP, for example, 61.139.2.69 and "backup DNS server" as 192.168.1.1.

◆ Step 4: Enable the "Internet Connection Sharing ICS" function of the wireless network card in the brain of the server. The method is to enable the setting up mode attribute of the wireless network, select "advanced", and select "allow other network users to connect through the Internet connection of this computer" in "Internet Connection Sharing ", and "allow other users to control or disable shared Internet connections ".

◆ 5. The soft AP configuration in the software is randomly configured by the manufacturer. In fact, the method is similar to enabling the ICS function. You only need to add the NIC connected to the Internet in the computer to its Internet connection list, then EnableICS enables ICS function), click Apply Application), and then the same function can be implemented.

After this setting, other computers in the Ad-hoc network that have the wireless network construction mode can access the Internet through the shared host. The host's wireless network construction mode has also become a "Wireless AP or wireless router" with NAT and DHCP servers.
