Windows 7 system set up 3G network card to achieve shared Internet access

3G era has come slower, after all, Europe has begun commercialization of 4G network. But there are better than nothing, better than the 2G and 2.5G eras. If the tariff policy is better, it is really a mobile phone to play around the network.

Just after the Spring Festival, I took the company's technical team and rushed to the company's new factory in the field to start the field work. Because it is working in the field, there is only a simple temporary shed as our office environment. Since I had a lot of personal business trips before, the company configured a WCDMA 3G network card for me. Although I can go online, my brothers sometimes need to download some information or keep in touch with the headquarters. In the absence of new equipment, is there any way to let the entire engineering team enjoy the convenience of 3G?

Ok, let's take a look at the specific solution -

Solution 1: Notebook + 3G network card

Equipment and operations I need:

My side is equivalent to "host", 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 Windows7. 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 up the Internet. After the connection is successful, my notebook can already go online.

Next click on the network connection icon in the lower right corner of the Windows7 desktop to enter the "Network and Sharing Center". Click "Set up a new connection or network" under the window, and then select "Set 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 select the prompt window. "Enable Internet Connection Sharing" in . A new wireless network connection in the "waiting for user" state will appear in the wireless network connection on the host side.

Equipment and operations that colleagues need:

Things are much simpler here. You only need a notebook with a wireless network card, and then search the wireless network as usual to find the name. "Outdoor" wireless network point "connection" (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 “everyone collects firewood high”, so we must find ways to reduce traffic and control. cost.

1. Mail first receives the mail header, encounters a large group of mails, which is collected by a colleague, and then shared locally;

2. Reduce the use of MSN, this IM software background traffic QQ is many times larger;

3. It can further close the picture display and sound display in web browsing, reducing traffic.
