WiFi passwords commonly used in general WiFi can be set to 8- 16 digits. Avoid setting simple and repeated passwords. Make the following suggestions: 1. WiFi password settings try to use passwords composed of letters, numbers and characters. This password is strong and not easy to crack. More combinations provide more possibilities and increase the difficulty of password cracking. It is suggested to increase the number and complexity of password characters. 2. When the router sets the wifi password, it is recommended to use the security mode of WPA2-PSK. Trademark routers all support WPA2. If you purchased an earlier model, we recommend that you switch to a new router that supports WPA2. Because it's safer and faster.
