I built a pc around 2 months ago. Ive had some problems with connection since and I havent known why. Today I checked the internet speed is 10 mbps when it was 100 on my old pc. I tested my old pc today with the same connection as on my main pc and it got 100/100. So is there a possibility that the new computers motherboard or something is slowing down the internet or what could it depend on?
