Okay lets tackle one thing at a time, Latency / internet stability would be the primary concern here.
What security programs do you use? if you aren’t using any third party apart from Microsoft, then Windows Defender will be the point of interest here.
Oh which windows are you using? Windows 10?
Have you tired to turn off the windows firewall?
You said that you are on a wired connection, how long is the cable? between the modem/router and the back of your computer/laptop?
I can’t give you all answers at this point as the above questions need to be answered so I can best help you.
