I’m looking at getting new internet at the house, and they’ve got their different packages (500mbps, 350mbps, 1gbps). I defaulted to “oh, I’ll get the 500mbps, that’s about what I’ve got with the other people”, but then wondered what I’m actually getting from anything that is sending data to me.
I know that this is about speed, not quantity, and so not looking for “I downloaded 800 gigs of linux ISOs last month”, but rather thinking “Youtube probably isn’t going to upload 200mbps to me.” But maybe something like Steam does when I’m downloading a game?
If I only ever have my actual real-world downloads surpass 350mbps a few times a month, then maybe I save myself $10/month and get that instead of 500mbps.
I have a TP-link router with their (updated) firmware/software, not one of those home-built routers with OpenWRT or something like that, so that will probably limit me since I want to know for the whole system, not an individual device and so the router itself is probably what needs to be measured…
Your modem will likely keep connection statistics which will tell you how much data was downloaded and uploaded.
Ookla speedtest.net will give you an indication of your network speed. I have a cron job that logs the speed with their cli client every 5 hours and I use it to keep my ISP mostly honest.
The resulting data can also be used to map peak network congestion so you don’t end up with network buffering issues when you are watching the latest episode on your favourite streaming service.
