First use the network cable to connect the wireless router and computer, input 192.168.1.1 Open the wireless router Settings page, login.
After opening the wireless settings here, open the wireless security settings, as shown in the figure.
There are 3 different modes of security settings, the most recommended WPA-PSK/WPA2-PSK is the most secure settings. Set the password here, can effectively prevent others to crack the password.
The above is done to set the router password, how to make their own WiFi network more secure, next look. Enter here in Wireless settings: Basic settings.
Set your own WiFi name here, which is the name to display when searching. The following open SSID broadcast is opened by default, we remove this hook, and after that, we can't search your wifi, we know the WiFi name to search, increase security.
After setting up no broadcast SSID, you will not see your wifi network here, we will find it elsewhere.
Then search yourself to set the SSID name to add, this is not a lot of security. Try it now.
