Probably kernel modules. Right now lsusb identifies the wifi device as
Bus 001 Device 040: ID 2357:012d TP-Link Archer T3U [Realtek RTL8812BU]

Running dmesg through grep wlan0 finds
[1549933.629235] rtw_8822bu 1-1.5.2:1.0 wlan0: disabling HT/VHT/HE as WMM/QoS is not supported by the AP

The wifi dongle works but not well. When the wireless connection gets
dodgy the entire USB system, including keyboard and trackpad, slow to
the point that the machine can't be controlled and must be power-cycled.

If I try 
bob@raspberrypi:~ $ sudo apt search rtw_8822bu
Sorting... Done
Full Text Search... Done

nothing is found, not even the existing driver.

Am I looking with the wrong tool?

Thanks for writing,
