These are older Wifi 5 chips. RTL8821AU is 1x1, with or without Bluetooth. RTL8812AU is 2x2, without Bluetooth. Beamforming is not implemented. It looks like these chips need a different implementation than what is in bf.c. Speed tests with RTL8821AU: 137 Mbps download, 144 Mbps upload. Speed tests with RTL8812AU: 344 Mbps download, 387 Mbps upload. RTL8812AU should be faster, but my router is currently limited to transmitting only one spatial stream due to a kernel bug.
