Driver downloads from Dell Support show as complete but are the wrong file size.

When downloading large driver files directly from the driver details page, files are sometimes a much smaller file size.  They show complete in the browser. They look like a proper .exe file, but are incomplete, and do not work.  After several tries I get the correct file size.  This has happened on different Inspiron model laptops.  Chrome and Edge browser.  After clearing browsing data.  Latest time happened on Inspiron 7300 2-in-1. Driver was Realtek-High-Definition-Audio-Driver_KKY25_WIN_6.0.9517.1_A84.EXE. File Size: 583.93 MB.  First try was 86.0 MB, second was 92.0 MB, third try was correct.  I checked the MD5 hashfile on each download and the third one was correct. The results are as follows:
