With the rapid development of network bandwidth, Wi-Fi has gradually gained popularity. One of the things I like to do on weekends is to come to "Starbucks", make a cup of coffee, open a Win7 computer, connect to Wi-Fi, and read the favorite e-book sample. When I met a favorite, I couldn't wait to go to the e-commerce website to place an order.
however, Win7 security documents tell me that personal information and files on your wireless network can sometimes be received network signal seen. This can lead to identity theft and other malicious acts. A network security key or password can help protect your wireless network from such unauthorized access.
For online shoppers who use online transactions, this means that all of our accounts, ID cards, and bank card information may be leaked. Therefore, setting a security key for Wi-Fi is imminent.
Introduction to Wi-Fi Technology
Before introducing the specific settings, let us first understand what Wi-Fi is. Wi-Fi is a technology that can connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones) wirelessly. It provides users with wireless broadband Internet access. At the same time, it is also a fast and convenient way to get online at home, in the office or on the go. The place where you can access the Wi-Fi network is called a hotspot.
Security Key Setting Process
Let's take a look at how to set up the Network Wizard to guide you through the process of setting up the security key. Click the Start button -> and then click Control Panel -> Open Set Up Network. In the search box, type Network -> and then click Network and Sharing Center -> Set up a new connection or network -> Set up a new network.
Wireless Network Encryption Method
There are currently three types of wireless network encryption: Wi?Fi 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 security key to connect. After the key verification is complete, the data sent between the computer or device and the access point will be encrypted. WPA2 authentication is more secure than WPA. Almost all new wireless adapters support WPA and WPA2, but some older wireless adapters do not. This mode is recommended for home networks.
2. WEP
When WEP is enabled, you need to set the network security key. A WEP key may encrypt information that a computer sends over the network to another computer. However, the WEP security mechanism is relatively easy to crack. Despite these warnings, if you still want to use WEP shared secret key authentication, you can follow these steps:
By clicking the Start button -> and then clicking "Control Panel" -> Open the Network and Sharing Center. In the search box, type network, and then click Network and Sharing Center -> Click Set up a new connection or network -> Click Manually connect to a wireless network, and then click Next -> On the "Enter information for the wireless network you want to add" page, under "Security Type", select WEP -> to complete the remaining operations on this page, then click "Next" -> Click "Change" Connection Settings -> Click the Security tab, then under Security Type, click Sharing -> Click OK, and then click Close.
3. 802.1x
802.1x is commonly used in corporate networks and is therefore not discussed here.
Wired Equivalent Privacy (WEP) is not recommended as a wireless network security method. Wi?Fi Protected Access (WPA or WPA2) is relatively secure.
