Discussing 2.4GHz and 5GHz devices on a single Wi-Fi network or router
The router features two distinct Wi-Fi networks: one for 2.4GHz and another for 5GHz. When scanning for signals, each network appears separately. Devices using only the 2.4GHz band connect to that network, while others use the 5GHz band. On your Asus router dashboard, it lists both 5GHz devices and 2.4GHz devices even though they’re connected to different SSIDs. This suggests they operate on separate networks despite sharing the same physical access point. When using an Elgato Key Light, which needs 2.4GHz for initial pairing, your 5GHz devices should still be able to communicate with it as long as both bands are accessible. However, switching back to 2.4GHz might simplify setup. Your concern about compatibility is valid—keeping some devices on 5GHz could streamline the process. The earlier experience with a Wi-Fi printer working across bands supports this idea.
Unless you use client isolation, users might communicate freely. I’ll test by sending a message on another Wi-Fi network. Generally, it’s recommended to keep one SSID active for both purposes.
I also like this approach. Each band has its own SSID. Typically, standard home routers using OEM firmware come with all connected devices on a single LAN by default. This means you’ll see every device in the client list. On 2.4GHz networks, clients can still talk to each other on 5GHz as long as they’re part of the same network.
