How to connect two laptops to the Internet and share the Internet surfing

Ad-Hoc network interconnection setting method for reference:

If the operating system is XP, the processing methods of other operating systems are similar;
Assume that both notebook A and notebook B have wireless network cards (WiFi). The method here can achieve their network connection without routing or network cable;
Assuming that notebook A can access the Internet, the method here will allow notebook B to access the Internet through a: Sharing Network Resources; tools/Raw Materials

• Laptop A and notebook B with wireless network adapter, and wireless network (WiFi) works properly

STEP/Method

3. Click "close", return to "wireless network configuration", click "add", and fill in the SSID in the pop-up window (you can write it as needed, for example: 123 ), network Authentication: open; Data Encryption: disabled; and select "this is a computer-to-computer (temporary) network", for example:
4. Click "OK" to close the window, return to the "General" tab, find and select "Internet Protocol (TCP/IP)", double-click to open (or click Properties ), fill in the IP information in the pop-up window, IP Address: 192.168.0.1, subnet mask: 255.255.255.0, for example:
5. Click "OK" to close the window, and then click "OK" to close the "Wireless Network Connection Properties" window.
6. In all network connections (SEE), find the connection for laptop a surfing the Internet (You may be using ADSL, 3G card, dialing, or other methods ), note that it must be the network adapter connection for your laptop to access the Internet. Generally, it is displayed as "connected" and working.
7. Select a connection that is surfing the Internet, right-click "properties" --> "advanced" tab, select the wireless network connection you just set in "Home Network Connection", and select the three check boxes.
8. Click "allow other network users to control or disable sharing..." on the right ", select" Web server "in the pop-up window, and click" OK ". This step is critical to determine which network services can be used by notebook B through notebook A (currently, only HTTP websites can be configured, and no emails can be sent and received). If you want to do other things, you can select the corresponding check boxes as needed. If you are not sure how to select the check boxes, you can select them.
   Now, the settings on notebook A have been completed. Double-click "wireless network connection" --> "view wireless network" in the notebook ",
   Click "Refresh Network List". If everything is normal, you can see the network connection from the computer set in step 1-3: 123 (SSID name, the image is the same as the image in Step 10.
9. Set notebook B now. Similarly, find the wireless connection on notebook B, similar to Step 4. On the "General" tab, find and select "Internet Protocol (TCP/IP )", double-click to open (or click Properties). In the displayed window, enter IP Address: 192.168.0.2, subnet mask: 255.255.255.0, and default gateway: 192.168.0.1 (the address of notebook A), for example:
10. Click OK to complete the settings. Double-click the wireless network connection. You can also see the wireless network with the SSID of 123, for example:
11. So far, all settings are obtained. Open the notebook A and B, and double-click the wireless connection "123" at the same time, let them initiate a connection, and soon it will be displayed "connected", it is done.

Notes

• Steps 1-8 are performed on notebook A; steps 9-10 are performed on notebook B; Steps 11 are performed on both notebook A and notebook B.
  The IP address set in the step can be set as needed, but note that the default gateway address of notebook B must be the IP address of notebook.
  Unable to access the Internet, or some network services are not available:
• For more information, see Step 8.
• Close the "firewall (and other firewall software installed on your laptop) on a and B. Close the firewall in XP as follows: Find" wireless network connection ", right-click Properties and the pop-up window --> "advanced" tab --> click "Settings". An example is displayed, and click "close:
