Update: I still haven’t been able to figure out what the issue is. I have no firewalls, and my speed has been stuck at 50mbps whereas it’s almost 500 on other distros like Debian, Arch, Void, openSUSE, etc. I’m not very knowledgeable in networking, and so maybe it’s my own incompetence at this being the problem.
$ inxi -n

I don’t see anything wrong with the output here, but my internet speed is horrible and it’s localized to OpenMandriva.
