Agree, should be WPA3 capable. The 2020 USB2 T2U drivers upgrade to WPA3, you'd think they woulda done same for USB3 T3U. I've read that TP-Link is very slow in updating software and firmware, like they release a product and then forget about it. Disappointed, being I got a T3U just today, then I could have set my TP-Link router to 'WPA3 only' for devices for better security. I'll make sure to state the lack of WPA3 support in my Amazon review.
