Hi hulley.
Right now, the driver situation is a big disaster. Many of the drivers are buggy, "not present" (rtl8812au) or doesn't support monitor mode (r8188eu). And there is no improvement foreseeable!
To make matters worse, latest chipsets requires exact this "ugly" drivers.
So it's possible that you buy a WiFi-adapter xxx rev A (with a working chipset/driver) and a xxx rev B (same case, but newer -not working- chipset/driver).
