I am using Networx 5.5.2 on a Win10 x64 system and Comcast cable for internet service.
When I run Networx Speed Meter, I get readings of 15 mb/s for downloads and 1 mb/s for uploads. When I run the online test at speedtest.net, I get readings of 180 mb/s download and 12 mb/s upload. When I run the test at speedtest.xfinity.com, the results are virtually identical to the speedtest.net results. The ping readings are almost identical on all three tests.
Why the disparity?
