WEP and WPA (along with WPA2) are names for different encryption tools used to secure your wireless connection. Encryption scrambles the network connection so that no one can “listen in” to it and look at which web pages you are viewing, for example. WEP stands for Wired Equivalent Privacy, and WPA stands for Wireless Protected Access. WPA2 is the second version of the WPA standard.

使用一些总是比不加密要好些，但 WEP 是这些标准里安全性低的一个，如果可能，您不应当使用它。WPA2 是三者中最安全的一个，如果您的无线网卡和路由器支持 WPA2，那么您在设置无线网络时应当使用它。
