Here's a problem with the windows 10 Speedtest.net app.

This developed in the last couple of days. When starting a test, the ping skyrockets up to 500, then the app shows a transfer rate of 5-10 MP download. This happens despite the speedtest.net server that is selected.

Running the speedtest.net test in a web browser shows download speeds of 240MB and pings of 33ms or so.

Pinging speedtest.net from a Windows 10 command line shows pings of 26ms.

The Windows 10 speedtest.net has been uninstalled and reinstalled several times, and the problem persists.

The problem happens only with the Windows 10 speedtest.net app, and there are no problems.

Speedtest.net has not responded to requests for help.
