USB-AX56 WiFi Adapter - How to Use Both Bands Simultaneously?

[Volt]

Recently I bought the USB-AX56 WiFi Dual Band AX1800 adapter and very happy with it. What I don't quite understand is that looks like ASUS states that this adapter can simultaneously work in both 2.4 GHz and 5 GHz bands when connected using WiFi 6 (so you can get 1200 Mbps + 574Mbps in total). Is it true that WiFi 6 can use both bands at the same time? And does anyone have experience with this configuration? Thanks in advance!

No, it doesn't work like that.

The + is just marketing noise. Best left ignored. (You can tell it's marketing by the wrong math too 1,200 + 574 doesn't equal 1,800).

Thanks for the answer! It also seemed suspicious to me that they indicate the total performance for the adapter, despite the fact that the adapter can only operate either at 2.4 or 5. Strange marketing decision!

Strange marketing decision!

All brands play the same marketing game. What do you think AX11000 routers are? The sum of maximum theoretical link speeds of all radios.

I have been looking at the adaptor. Initially considered NetGear but read on AMZN that is doesnt have 160MHz Channel Support, which my ASUS XT9 mesh does. Does the AX56 suppport 160Mhz?

For background:
160MHz Channel Support:
60MHz is the highest bandwidth available on 5GHz routers. With double the throughput compared to 80MHz channels, it can achieve data rates up to 2.4Gbps on capable clients. However, it is important to know that not all client devices support 160MHz wide channels.
