After following another guide it suddenly got fixed, I turned off the feature 'Use Proxy Server'.. don't know why that was on. Thanks for trying to help!
When I booted up my pc today I didn't have any internet, even though my ethernet cable says it's connected. I checked if the problem was with my cable, by connecting it to my laptop, It worked perfectly on my laptop so it's not that.
I've tried numerous fixes; Restarting the router, ipconfig...
