> which indeed no device currently supports

Aren't devices with Intel Wi-Fi 7 BE200/BE202 are supporting that?

As well as latest Samsung phones?

AFAIR: the BE200/B202 only have one radio. So no parallel streams on two frequencies.

But they are the best cards around if you want to play with Wifi-7 on Linux. But always go for the latest wireless-next kernel + firmware blobs. Also they are not compatible with AMD mainboards (go for Qualcomm then).
