How to set the WiFi security key to ensure the security of WiFi in Win7 system

Now with the development of the network world, WiFi has become a very important way to access the Internet. In order to ensure your own speed, so you can surf the Internet, avoiding your own WiFi is an important way. Today Xiaobian teaches you how to secure WiFi by setting a security key.

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 “Start” button -> and then click “Control Panel” -> Open “Set Network”. In the search box, type Network -> and then click “Network & Sharing Center" -""Set up a new connection or network" -" "Set new network".

Encryption methods for wireless networks

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 - then clicking on "Control Panel" - " Open “Network and Sharing Center”. In the search box, type network, then click “Network & Sharing Center" -> Click “Set New Connection or Network" -> Click “Manually Connect to Wireless Network", and then click “Next,” -" Under "Enter the information of the wireless network you want to add", click "Security Type", select WEP -" to complete the remaining operations on this page, then click "under" One step & rdquo; -> Click “Change connection settings”-> Click the "Security" tab, then click “Share” -> Click “OK> ;, 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. WiFi-protected access (WPA or WPA2) is relatively secure.

This is how several different WiFi security key settings are made. Users who are often smashed by the network are set to set a security key for their WiFi.
