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.
| Speed | Against Obstacle (Recommendation) | SSID e.g. | |
| 2.4G (2G, g) | Middle | Strong (Different Room) | TP-Link_XXXX MOTO XXXX aterm-XXXX-g |
| 5G (a) | High | Weak (Same Room) | TP-Link_XXXX_5G MOTO XXXX-5G aterm-XXXX-a |
The table shown above will make you enable to tell 2.4G from 5G. The key is to take a look at the end of the code. If you can reach the WiFi router, look at the back of it. You can find more information about SSIDs with a password. Take a picture of this information!
If you have to set up a WiFi router at home, I recommend using top-selling models, e.g. TP-LINK AC1750, to avoid involving in a sticky situation. It's easy to find a review of how to set up.
Learn more! Tip for understanding
WiFi router delivers information using radio waves. The wave can detour the obstacle. The ability of detour depends on its wavelength.
| Ability of detour | Wavelength | Speed | |
| 2.4G | Strong | 12 cm | Middle |
| 5G | Weak | 6 cm | High |
| 60G (Coming Soon) | Very weak | 5 mm | Ultra High |
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.
