Dear karlbeckman,

 

I am sorry for the delayed reply.   I have returned from my business trip and had the opportunity to follow the suggestions in your reply.   It was a Windows 10 issue that caused the internet speed slowdown.    I enabled the "Receive Window Auto Tuning Level" and the Speedtest result showed 342 mbps for download and 23 mbps for upload.   I am very grateful to you for spending your time to help me.  Again, tip of the hat to you.

Good that this got fixed!

 

This feature is supposed to be enabled by default in Windows 10.  But if your router or firewall is old causing connectivity problems, it can be turned off.  It has been around since  Windows Visa:

I think this 1803 build is the April 2018 Update.  The Fall Creators Update, build 1709 was the one before that.
