I don't even understand why

Alright so I just got into playing and started on Lorderean server, I had very few disconnect issues three or two days ago when i joined, maybe two disconnects over 6 hours of playing. Since then, upon launching the game, it takes down my internet until i minimize it whereby my internet comes back online. I rarely get past the login screen without having my internet just shut down in response. I couldn't find a solution so im looking to others to find out if this is some easy fix.

i'm on windows 10 with solid hardware I've put together, haven't had this computer for a year yet.

What i've tried:
turning off firewall
redownloading the application
