While that's true, I had NetWorx installed until I had to restore with an older system image a little while back, and it was always within about 2Mbps of my testmy.net results. I have had skewed results in the past, which is one of the reasons I installed Networx in the first place.
My normal speeds are around the mid 20s, sometimes going up into the lower thirties, like that test, but NEVER at 10PM. I just ran another one and it was 24.5Mbps, but I'm now starting to get into where it will normally speed up for me.
BTW, below is a test I had done about five minutes earlier while trying Firefox (the reason it's not signed in). Just VERY unusual for me to get these speeds at 10PM. Something is a bit different tonight.
