I've been using an old MSI Wind PC as a home server and yesterday, something odd happened. Suddenly, pretty much out of nowhere, my ethernet connection became really slow to the point where even streaming a file via a SMB share or logging in via RDP was arduous and close to impossible. I've never had any experience with anything like this and was hoping somebody might have some insight. I did not install any new software, including Windows updates so by all accounts, nothing should have changed. I'm stumped.
