Unsolved Install for home use fails with network error

[BKBK]

I am trying to install the latest version of QT at home on Windows 10 so I can learn about it for use at work. It begins the install but after about five minutes it quits and declares:
Network error while downloading 'http://download..qt.io/online/qtsdkrepository/windows_x86/xxx
I put the xxx there because I tried this four times and every time the result was different at that point. I cannot tell if the download is saving data and will eventually get everything, or if it starts at the beginning each time and quits at different places.
Is there some method I can use to manually download all the files and tell QT installer where to find them?
Is there any additional information I can provide?
