Needed a #USB3 #Wifi6 adapter for my backup server, as the old atheros 9k got flaky. Found this Mediatek based nic supported by mt7921u driver in #linux kernel 6.1 + firmware blob (firmware-misc-nonfree package on #debian). My dhcpcd immediately got dhcp lease upon plugging ('n-play). The device came with high gain antennas and was only $25!!
