How To Use 2.4GHz and 5GHz at the Same Time

How to Use the 5-GHz Band on Your Router

Will my phone and tablet switch automatically between the bands? It depends on your device . Older devices might not be able to connect to the newer 5GHz band at all, while others will flip seamlessly between them.

You can connect to the 5GHz when you’re in your main work/recreation space, then switch to the 2.4GHz when you wander a few rooms away . If your devices seem to connect to the 2.4GHz network by default, or if you just really care about optimizing your speed, separate SSIDs are the way to go.14 May 2021

Separating the bands of the router may help you to maximise the WiFi speeds around your home . 2.4Ghz (gigahertz) can cover a further distance from the router, however the connection speeds are slightly slower. 5Ghz covers a shorter distance from the router, but the speeds are faster.

As long as your network design is good, your devices should choose the best frequency for the circumstance. Older 2.4Ghz only devices will just connect to the 2.4Ghz frequency and not even see the 5Ghz frequency, so having the same SSID will work fine for them .
