High speed is not always the best choice.  How to choose the best SSID for your Wi-Fi at home

When you try to connect WiFi at home, have you ever seen two kinds of SSIDs containing the number 2.4 or 5, or the character g or a? WiFi routers offer two kinds of SSIDs simultaneously nowadays. Multiple choices make us confused.

2.4G or 5G? It depends on obstacles between your device and WiFi router

It's all up to your environment. 5G is faster than 2.4G, but 5G is more vulnerable to obstacles than 2.4G. If there are obstacles such as a wall, a door, a ceiling or a floor between your device and WiFi router, your best choice is 2.4G.

Next-generation, ultra-high-speed 60G, will be very weak to any obstacles. So the user might have to stay close to the router. It must be more inconvenient for users if there is no improvement in usability.
