Hello Gabor,

bad guy is back again :-)

I did another test with raspberry pi. Same network parameters (2.4 GHz,
40MHz, eap-tls, ccmp/ccmp) but this time w/o any other load on the
wlan. But there is a reinforced-concrete floor between AP and STA.

netperf with rt2800usb / backports-20130617 / kernel 3.6.11 gives:

If you compare the result w/ rt2800usb/AE3000 with rt2800usb/rt3572[1]
you can see: no difference :-(.


Kind regards,
