Slow speed with AWUS036ACH USB WiFi Adapter
I'm using AWUS036ACH USB WiFi Adapter with aircrack-ng/rtl8812au drivers and my speed varies between 60 and 100Mbits/sec. No matter if I connect this adapter to USB2.0 or USB3.0 I get similar speed. (by checking USB ports it says that device operates at 5000M)
When connecting the same adapter to my laptop I get speeds between 350-400Mbits/sec.
Same drivers and same Ubuntu 16.04 used.
Any idea why Intel UP is lowering speed of this USB WiFi adapter?
