No idea, I was told that the ping fill results show a round trip results.
And that what ever I got in the ping fill will only show transfer half of
the results in one direction or the other. That I can prove wrong. What I
dont understand that if the ping fill is showing true duplex results as mine
seems to be then why am I getting less than half my 3MB/S feed at the
KN-200? The link is -47db signal and this is at the KN-200.
