Both RTL8812AE and RTL8821AE have wifi and Bluetooth. There is a difference in 
the radio structure. The 8812 has the potential to handle 867 Mbps - the 8821 
only half that rate. In any case, driver rtl8821ae handles both devices, and the 
firmware is the same. One other difference is that I have not tested the 8812 as 
I only have 8821 devices.

One other difference is that the firmware can handle BT coexistence internally 
in the 8821, but not in the 8812. Realtek is still working on getting a method 
of handling that problem. None of the Realtek Bluetooth adaptors has a driver in 
the kernel. Fixing that issue is my current project.
