How does the router prevent others from smashing the network?

Recently, a small friend asked Xiaobian how the router can prevent others from smashing the network. In fact, the router is relatively simple to prevent others from smashing the network. The following is a tutorial for the router to prevent others from smashing the network. 1. Turn on WPA2 and set up the network You can enable WPA2 encryption through the steps in the router manual. Maybe you can change your password to prevent it from being smashed, but WEP's protection measures are too old and too fragile. Even if you find some free tools on the Internet, you can decipher them in 2 minutes. So open WPA2 for encryption and set a strong password. 2. Change your wireless network username (SSID) SSID refers to your wireless network username. You should modify this default ID from the manufacturer settings. Because the ID is usually the brand name of the router. Such as D & mdash; link, Tenda and so on. Changing the SSID helps prevent others from finding the router's vulnerability through the brand and deciphering your password in a specific way. If you haven't changed your password yet, the brand name may also let them pass the experience of their own "guess" 3. Turn off the "Allow external personnel access" option on your wireless router. As a precautionary measure for the anti-mite network, turn off the function of "Allowing outsiders to access" on your router. This can effectively prevent others from smashing the way through your router. Turn off this feature, your router can only be connected to the computer directly connected through the network cable. That is to say, unless they come to your house, don’t even think about your network.
