All Speedefy routers support both 2.4 GHz and 5 GHz WiFi networks, the "Unify 2.4 GHz & 5 GHz" function is enabled by default.
When this function is enabled, the 2.4 GHz and 5 GHz WiFi networks share the same SSID and password. Devices connected to the WiFi network will use the network with better connection quality automatically. If you want to separate the WiFi names of these two networks, please disable this function, then you could set different WiFi names and passwords for each frequency.
Here is how to:
Launch a web browser from a computer or mobile device that is connected to the network. Enter http://www.speedefywifi.com or 192.168.3.1
Choose WiFi Settings > WiFi Name & Password.
Disable Unify 2.4 GHz & 5 GHz.
Customize the WiFi Name and WiFi Password of each WiFi network.
If the wireless devices such as mobile phones are far away from the router, or
blocked from the router by a wall, it is recommended to connect to the 2.4 GHz
If the wireless devices are close to the router, it is recommended to connect to the
5 GHz network.
