-Question: What interface combinations does this driver support?
-
-Answer: None. Realtek out-of-kernel drivers, including this driver, do not
-support interface combinations. If you need support for interface combinations,
-I suggest adapters based on the Mediatek chipsets.

-Question: What extended features does this driver support?
-
-Answer: None. For extended features, you need an adapter that uses Mediatek or
-Atheros drivers.

 Question: I bought two rtl8812bu based adapters and am planning to run one of them as an AP and another as a WiFi client. How do I set that up?
 
 Answer: You can't without considerable technical skills.  Realtek drivers do not support more than one adapter with the same chipset in the same computer. However, testing has shown that the Mediatek drivers do support more than one adapter with the same chipset in the same computer.
