I have a Dell Precision 7510 (connected to ethernet) and just a couple of days ago I started getting ping spikes ingame. I have run several download and upload speed tests and my download speed is down to about 35 megabits/second (used to be 60+). I connected ethernet to another laptop and also got 60+ megabits/second. I've tested several cables and I'm fairly certain it is a problem with my actual laptop. Any suggestions to further troubleshoot?
