Windows 7 Powerful security WiFi set security key

With the development of science and technology, wireless internet technology is more and more mature and popular, and WiFi coverage point is more and more, I like to do a weekend thing is, came to the café, bubble a cup of coffee, open Win7 computer, connect Wi-Fi, enjoy the world in the network roaming.

The so-called Wi-Fi, is a personal computer, handheld devices (such as PDAs, mobile phones) and other terminals to connect to each other wireless technology. It provides wireless broadband Internet access to users. It is also a quick and convenient way to surf the Internet at home, in the office or on the road, where access to Wi-Fi networks is known as a hotspot.

However, there is a security risk that personal information and files on a wireless network can sometimes be seen by people who receive network signals, which can lead to identity theft and other malicious behavior that has been mentioned by more well-known security software vendors. However, in a highly secure Windows7 system, we can set a security key for WiFi, which protects our personal information to a large extent.

The following author to take you to see how to set up the WIN7 System Network Wizard, guide you to complete the security key setup process. In the lower-left corner of the Win7 desktop, click the Start button-> and then click Control Panel-> Open Network and Internet. Then click Network and Share center-> to set up a new connection or network "->" to set up a new network.

There are currently three types of wireless network encryption: WiFi Protected Access (WPA and WPA2), Wired Equivalent Privacy (WEP), and 802.1x.

1.WPA and WPA2

WPA and WPA2 require the user to provide a secure key to connect, and when the key is authenticated, the data sent between the computer or device and the access point is encrypted, which is more secure than the WPA,WPA2 authentication. Almost all new wireless adapters support WPA and WPA2, but some older wireless adapters are not supported, and it is recommended that the home network adopt this mode.

2.WEP

When WEP is enabled, you need to set the network security key. The WEP key may encrypt information that a computer sends to another computer over the network. However, the WEP security mechanism is relatively easy to crack. Although you are aware of these warnings, if you still want to use WEP shared key authentication, you can follow these steps:

Open Network and Sharing Center by clicking the Start button-> and then clicking Control Panel->. In the search box, type the network, then click Network and Sharing Center-> Click Set up a new connection or network-> Click Connect to wireless network manually, and then click Next-> under Security type on the Enter information for the wireless network you want to add page, select WEP-& Gt Complete the remaining actions on the page, and then click Next-> Click Change Connection Settings-> Click the Security tab, and then under Security type, click Share-> Click OK, and then click Close.

3.802.1x

802.1X is usually used for enterprise network, practicality is not strong, I also know very little, do not swim a fish.

With the above settings, do you still worry about your Win7 computer being hacked when you're relaxing in a café with WiFi? Win7 system for us to consider these wireless WiFi privacy settings, let us no matter where, can be assured of using their own Win7 computer Internet Office Entertainment.
