How to Configure Dual Band WiFi

Steve C · 09 May 2023

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?

its a fallback system so you can have access to both and connectivity will prioritize to the faster 5ghz connection if that connection for what ever reason is not happening then it will go to 2.4g instead. There is math to it but basically its one or the other.
