Known problem of rt2800usb. You might try the original vendor driver[1] if you want to use the device as STA. Are you running this test on ARM? rt2800usb runs *extremely* poor with Raspi, e.g. With the vendor driver rt5572..., I'm getting > 100MBit/s (measured w/ netperf) running at 2.4 GHz and 40 MHz even through reinforced concrete floor using a rt5372 chip, e.g. - even w/ Raspberry Pi.
