Thanks for answering. At least the module from the aircrack-ng-project (https://github.com/aircrack-ng/rtl8812au) did load.

@Nazdravi  Hello, 

Tp-link official Linux driver supports up to kernel 5.0 model Archer T2U  ( V3: chipset model ' RTL8811AU')
The driver may report error when working on a newer kernel,  as Linux is an open source system, it is recommended to check if there is any third party drivers available on GitHub made by other developers for  “RTL8811AU” ,hope this could help:
