Win8.1 system wireless network encryption skills

When using wireless network, is it often worried about their own WiFi "being smashed network"? We can set MAC filtering in the router, or in the Win8.1 system Settings so that only allowed people are allowed to access the network. The following is a small series to introduce you to the Win8.1 system wireless network encryption skills.
1. Wi-Fi Protected Access (WPA and WPA2)
Wi‐Fi Protects access to encrypted information and ensures that the network security key has not been modified. Wi‐Fi Protected Access also authenticates users to help ensure that only authorized users can access the network.
There are two types of WPA authentication: WPA and WPA2. WPA is designed for all wireless network adapters, but may not work with older routers or access points. WPA2 is more secure than WPA, but it cannot be used with some older network adapters. WPA is designed to distribute 802.1X authentication servers with different keys to each user. This is called WPA-Enterprise or WPA2-Enterprise. WPA can also be used in Pre-Shared Key (PSK) mode, which grants each user the same password. This is called WPA-Personal or WPA2-Personal.
2. Limited Equivalent Encryption (WEP)
WEP is an older network security method that can still be used to support older devices, but it is recommended that you do not use it. When WEP is enabled, a network security key needs to be set. This key may encrypt the information that one computer sends over the network to another. However, the WEP security mechanism is relatively easy to crack.
System Home Suggestions: It is recommended to use WPA2 whenever possible. It is recommended that you do not use WEP. WPA or WPA2 is safer. If you are trying to use WPA or WPA2 but they don't work, it is recommended that you upgrade your network adapter to an adapter for WPA or WPA2.
3.802.1X Authentication
802.1X authentication helps to enhance the security of 802.11 wireless networks and wired Ethernet networks. 802.1X uses an authentication server to authenticate users and provide network access. On a wireless network, 802.1X can be used in conjunction with WPA, WPA2 or WEP keys. This type of authentication is typically used when connecting to an office network.
