Deco supports disabling 2.4GHz and 5GHz separately under the Main/Guest/IOT networks.

As for separate SSIDs over 2.4GHz and 5GHz, it might not be completed via a single network, But you could set the Main Network to 5GHz only, and then create a different SSID for the 2.4 GHz only IOT network.

“One Network” is widespread in Mesh networks in order to enjoy seamless roaming, which is different from non-mesh traditional routers that require you to connect to the band you want manually. So we tend to remain one SSID per network, and Deco keeps its network simple by automatically choosing the band that gives you the best wireless roaming experience. It uses the same name for both the 2.4ghz and 5ghz bands under the same network. Both radio bands are active simultaneously. If the device is only compatible with 2.4 GHz, then it won't try to connect to 5 GHz. And if it supports both, it will connect to only one radio band at any given time. Based on the device's capabilities, the Band Steering feature of Deco will attempt to guide your connected devices to the band with the best performance.

So if you want separate SSIDs over 2.4 GHz and 5GHz Wi-Fi  here is what you could do:

• Turn off 2.4 GHz under the Main Network.
• Enable the IOT network with a different SSID under 2.4 GHz only.
