Create a temporary Wireless Network

First, let's talk about the requirements for wireless Internet sharing:
1. All computers (including desktops or laptops) must have wireless NICs, such as two laptops with wireless NICs.

2. One of the operating systems is Windows 7, but it is not successful in xp. Other computers are not limited.

Then, use the network cable to connect the computer with win7 installed to the Internet. If the dormitory has multiple win7 servers, select one server with better configuration as the wireless network access

 

Step: First Open Control Panel-network and Internet-network and sharing center, then select set new connection or network, and select "set wireless temporary network" in the pop-up window ", click Next.

Next, you need to name your network and set a key. This can be done at will. For "Security type", select wpa2-individual.
Finally, after the network is set, click "Enable Internet Connection Sharing" and set this computer in win7.
Search for the wireless network on another computer, find the set wireless network, and enter the password to connect.

However, Internet access through this sharing method is slow under 2 m broadband in our dormitory, but it is enough for daily Internet applications.

In Linux, you can directly create a wireless network in network management, and select WEP as the key type.
