No, I didn't know that.  I was wondering why my speeds weren't very good
right now.  I bought a couple of Ralink RT3071 based adapters and they
seem to work reasonably well, but not as fast as I was hoping.  I am
getting only about 12Mb/sec now according to iperf3, but I don't really
need faster speeds.

Thanks for your information.
