How to Configure a Dual Band MOdem

[steve489]

I've built a new PC using an Asus Z790 motherboard having Wi-Fi 6E (2x2 Wi-Fi 6E (802.11 a/b/g/n/ac/ax)) which supports the 2.4/5/6GHz frequency bands. I also now have a new fibre to cabinet 75Mbs broadband service supplied with a Zyxel DX3301-TO
dual-band DSL modem covering both 2.4GHz and 5GHz bands.

Is there a way of configuring Windows to use both bands simultaneously or do I have to choose whichever band gives the best signal? The modem can be configured to use the same or different networks names for each band. Which should be used?

Devices can only use one band at a time.

Also most Wi-Fi access points as far as I'm aware of allows you to set up networks on both 2.4 GHz or 5 GHz at the same time.
