Solution 1: Notebook 3G Network Card I need equipment and operation: I am equivalent to the host here, the basic equipment needed is my own notebook and 3G network card. Of course, this notebook must have a wireless network card (or how to connect a colleague's notebook?), the operating system must be Vista or Windows 7. The following example uses Windows 7, and the operation method of Vista is the same. First of all, I installed the 3G network card here, and turned on the computer's wireless network switch (soft/hard off is on), double-click the Unicom dial-up program, use the default Unicom as the dial-up link to dial the Internet, my notebook after successful connection Already available on the Internet. Next click on the network connection icon in the lower right corner of the Windows 7 desktop to enter the Network and Sharing Center. Click Set up a new connection or network below the window, and then select Set up a wireless temporary (computer to computer) network in the window. Then in the Set Temporary Network window, set the new network name shared to colleagues (here I set to outdoor) and the encryption type. In order to ensure that the computer using Windows XP can also access smoothly, it is recommended to select WEP in the encryption mode (ie security type). The WAP2 mode and the non-encryption mode are not recommended. When these settings are done, our WLAN is built, but Windows 7 has not bridged the 3G network with this new wireless network, so in the next step, remember to enable Internet connection in the prompt window. shared. At this time, a new wireless network connection waiting for the user state will appear in the wireless network connection on the host side. Equipment and operations that colleagues need: Colleagues are much simpler, just need a laptop with a wireless network card, then search the wireless network as usual, find the wireless network point connection called outdoor (the network name can be set by yourself) , not necessarily called outdoor), and then fill in the password to successfully connect, you can share 3G Internet through my laptop. Tips: Pay attention to saving traffic Although 3G Internet access is convenient, the cost is still not cheap, especially in the case of high firewood collection, so we must find ways to reduce traffic and control costs. 1. The mail first receives the mail header, encounters a large mass mail, is collected by a colleague, and then shared locally; 2. Reduce the use of MSN, the background traffic of this IM software is many times larger than QQ; 3. Can further close the web browsing The picture in the display and the sound display reduce traffic. Solution 2: Notebook 3G mobile phone If you don't even have a 3G network card under special circumstances, can you share the Internet? The answer is yes. Solution 1 is not the most cost-effective trick, as long as you have a 3G mobile phone, as long as it is not too slow, 2G mobile phones can also build a wireless LAN that shares Internet access. Below I will use a Windows Mobile 6 mobile phone as an example. Other operating system mobile phones, such as Android, Saipan S60, and even the old version of Windows Mobile 2003 are also possible, but the operation is more troublesome, here is skipped. . The device I need is still a notebook, and another 3G phone. First connect the phone to the notebook with a USB cable. Select Program - Internet Sharing on your phone. Then select GPRS to connect to the Internet (2G network) or UNICOM to connect to the Internet (3G network) at the menu item network connection, and then click the connection. At this time, the Windows Mobile Device Center on the host side will set the network in the background. Next, repeat the steps from setting up a new connection or network in scenario 1. Colleagues need the same equipment and operation as the solution. In this way, our team realized 3G network sharing without any other equipment.
