Dear All.

I've tplink usb AC adapter with 1200Mbit 5ghz AC 4antennas and with 3Streams.

The TX-RX just 300Mbit,but the connection is 975Mbit/80Mhz/3S/SGI
I tried with a 2 streams 867Mbit wireless adapter and the issue same.
RX-TX test is just 280-300Mbit.
The CCQ is between 91%-100%

I tested with the btest.exe.

Any suggestion? Thanks.

Your USB standart?
USB 2 maxes out at 480MBit theoretically, so 300MBit over USB2 would be good speed

No, this is a 3.0 USB adapter. Very strange because the 867Mbit(2 stream 2 antennas) usb adapter and the faster Tp-link(3streams 4 antennas) show same speed, maybe the client side(Windows 10) has a wrong setup?
