I have no idea what is going on with my PC and I've done so much research to no avail. So my friend brought his pc over today so I could help him put some new parts in. I literally unplugged the ethernet from my pc and plugged it into his and ran an internet speed test once we got it up and running and he was getting 220mbps. Which is normal. Its what I pay for. But for the past few months, I can't get more than 16mbps when I run the same speed test with the same ethernet cable going to the same router. When I run my avast it comes up with no virus' or bugs. I've messed with the speed and duplex setting in windows went from wireless to ethernet. I'm not sure if I have a hidden virus the program can't find or if I have some hidden setting turned on that is limiting my speed. Any advice would help. Thanks.
