Reading through a bit it sounds like it works on Linux, not on Windows. Folks are hypothesizing it’s disabled at the ACPI level because different drivers don’t help.

In my area Xfinity cable has decent upload now, though it still trails fiber. Doing a speed test just now I get 2 gigabit down and 300 megabit up and I pay $85/month with a five year price lock. This is a relatively recent phenomenon so worth checking out if you can get a similar package. Prior to this I was getting 25-32 megabit.

I’ve never made my friends or family pay, but prior to getting decent upload bandwidth I did cap remote streams / concurrent transcodes and let people duke it out fist come first serve. Mostly it was fine. I’ve given maybe 15 people access, but only a few are regularly active.

I also keep a small offsite server at a family members house that splits some of my user base and serves as an offsite backup.
