Remember! Wifi password don't tell anyone easily

A friend of mine was specifically installing mobile broadband. Today, I asked him if wifi is always being hacked by other people. I asked him whether Mobile Broadband can change the password. He said that it can be changed, but it is not changed by others. The problem is not that the password is changed, but my password once told others, but my friend who used my wifi password, he installed on the phone, the principle of ** is this: it can not crack the password itself , It is through all people who have installed ** to share with each other to achieve "cracking" someone else's password.

A large number of people are jealous of your wireless network, resulting in your network. The rapid decline, but you can not find the reason, always thought it was a problem with the cable, or complain that the current network quality is so bad.
