Hi, some people mentioned that Apple does not include the latest Wifi 6 in the MBP 16" 2019. If we add a Wifi 6 dongle to the laptop (perhaps usb-c based wifi6 dongle?), will it perform equally well as laptops with wifi 6 buit-in? Not sure if there will be problem with a lack of driver under MacOS, Windows and Linux. Actually, is the increased performance of Wifi 6 noticable?
