Two wireless network cards are connected to the Internet...

I am on a business trip with my colleagues. I have two wireless computers and only one network cable can access the Internet. Even if the configuration fails for half a day, after 10 years of it work, the sweat flow. In the end, Google is the only one. I still find a good article. Save it in a timely manner.

Among them, the configuration of Vista has been verified successfully. From http://fangzhifeng2002.blog.163.com/blog/static/2289593200852855053285/

For everyone who is using computers, the network is one of the essential parts for Matching computers. Especially for laptops, the laptop is designed for mobile office, networks and offices are also inseparable, but for those of us laptop users, this problem is often used: Sometimes there is only one network interface, but there are multiple computers to access the Internet, what should I do?

The answer is simple. You can use wireless Internet sharing.

Solution 1:Use a wireless router. This is the simplest method, but the premise is that the laptop must have a wireless Nic module; otherwise, only wired ports are used. The configuration of a wireless router is very simple. Taking the author's D-link 624 + A as an example, you only need to open the browser and enter 192.168.0.1 to enter the router operation interface. According to different needs, you can select pppoe (dial-up Internet access), static IP (fixed IP), and so on. For details about Slim operations, see vro instructions.

Solution 2:However, if you go out, it is inconvenient to bring a wireless router with you. Currently, a Mbps network connection port is provided in hotels, school dormitories, and other places, in this case, only one computer can access the network. But now most laptops are equipped with wireless NICs, so that one of them can connect to the network through a wired connection, and then connect other computers through a wireless Nic, in this way, you can access the Internet at the same time. If you do not have a built-in wireless network card, you can also use the wireless network card of the USB or pcmica interface. Generally, the wired network of a hotel or school dormitory uses DHCP to automatically allocate IP addresses. In this case, the "dual-host wireless couplet + bridge" method is used to access the Internet. First, connect computer A to the wired network, and computer B to connect to computer A wirelessly.

If the operating system isWindows XPWords

The configuration of A is as follows:

1. Right-click "Network Neighbor" and select the "properties" tab. The "properties" of "wireless network connection" is displayed, and "wireless network configuration" is selected ".

2: click "advanced", select "computer only to computer" in the window, and check the box "automatically connect to a non-preferred network.

3: Go back to the "wireless network configuration" page, click the "add" button under "preferred network", enter the network name (such as Connect), and set "network verification" to open, set "Data Encryption" to disabled.

4: Select "Local Connection" and "wireless network connection" on the "Network Connection" page, and right-click and select "bridge ".

B's configuration is as follows: Double-click "wireless network connection". Then, you can see the connection from the computer named "Connect" to the computer in the list, after double-clicking, you can communicate with the computer. Now both computers can get the IP address and access the Internet normally.

If the operating system isWindows VistaThe configuration is simpler.

For host a: first, go to "manage wireless networks", click "add", and select "create temporary network". Then, you 'd better select "no authentication", which makes it easier to use. This completes the Wireless Configuration. Next, go to "manage network connections", Press Ctrl, select "Local Connection" and "wireless network connection", right-click and select bridge. Note that, this process requires administrator permissions. If you are in trouble, you can disable the User Account Control of Vista. After the "bridge" is created successfully, as long as a is inserted into the network cable, B is connected to a wirelessly, and the two machines can access the Internet normally.

Solution 3:Now, ADSL networks are used in many places, and "dual-host wireless couplet + bridge" is ineffective. The main reason is that as long as one of the computers dials, the other one can no longer make a dial-up connection. How can this problem be solved? This requires the help of the agent software. First, set a to 1 ~ 3. Follow the preceding steps. Next, double-click Internet protocol TCP/IP under the "wireless network connection" and "properties" "regular" labels. Enter 192.168.0.1 as the IP address and the subnet mask is 255.255.255.0. Similarly, you also need to change the Internet protocol TCP/IP in B. Enter 192.168.0.2 as the IP address, set the subnet mask to 255.255.255.0, and the default gateway is 192.168.0.1. Then search for the wireless network and connect to "Connect ". Then run the proxy software CCProxy on a, select "DNS" and "webpage cache" in its settings, and remove "Automatic Detection ". Select 192.168.0.1. Then run the proxy client software ccclient on B, enter 192.168.0.1, and click "Start proxy.
