I have an Asus Sabertooth z87 and I have been playing games on it for a month now. People always say my skype is laggy and I run into lag in game. But then everytime I run a speed test my ping is around 17-20, my download speed it 57-60mbps, and my upload speed is about 11-12mbps. I don't understand what could be wrong. I am connected to ethernet but I am starting to think the on board ethernet plug is crappy. And I am positive my drivers are all up to date. Should I try getting a ethernet card to see if it helps? And if so what should I get? Any advice will help.
