Connection error NET help!!

So after losing around 300 RP this week due to DC’s from losing connection to the servers, I’m a little more than frustrated. I’ve been without connection issues since release until this last week and a half. Now nearly 1/4 games I get DC’d for no reason and not only do I lose my RP but my friends don’t get loss forgiveness. I have a direct wired connection to my gateway router. I don’t know what to do and this is killing me.
