Unreal lag

So i got the game and it was running perfect for a week then it started lagging i didn’t think much of it because I’ve had online games lag occasionally before but then it kept happening day after day and its to the point now where i cant even play a game what the heck is going on. my internet hasn’t changed my settings haven’t changed but for some reason after a week of it being perfect its now unplayable any ideas ive goggled it but no one has any useful info. I dont have anything downloading or streaming and literally nothing has changed from when it ran great im really bummed out i haven’t finished a game in 2 days now.

Yeah I have been having it since Friday, so I stopped playing.
