Well, if your AP which you are connected from Windows host
has linux based firmware (what is most probable), then linux
is capable to transfer also at 10-15 MiB/s :-)

But yes, I never achieved more than 10MB/s on linux station.
Best results I have is about 7.5MB/s on 2.4 GHz networks and
10MB/s on 5GHz .
