How to tell if my network's faulty? (programming.dev)

I have a number of hints that my internet connection doesn't work right. I see things like can't connect to addresses from docker, pages will be slow in my browser. Before I used ethernet to my router, I would sometimes disconnect from the internet. Aside from disconnecting, none of it was a clear sign something is unusually broken. Is there some linux (Ubuntu) tool I can use to assess the long-term health of my connection?

A nice to have: the tool would tell me whether a fault is in my drivers, settings, adapter, router, connection to the house, or my provider.

do you know if there's a free version of gatus? I could only see a 7 day trial

Tried it a few months ago, self hosted was free https://github.com/TwiN/gatus

(Otherwise uptimekuma or something, there are plenty of tools out there. If you wanna do it right 1st time for free : checkmk and or librenms, but it might be overkill for you just yet)
