It took me almost an hour to dl the last update and I have a fast
connection, over 200mbs. Why? Because it wouldn't dl all at once. It
would stick at different percentages for a long time.

Same here, I have ~80Mbps, two attempts stuck at various percentages and
eventually failed, another one failed because I got impatient and
rebooted, for the fourth attempt I left the machine alone for an hour
with nothing running and it managed to install.
