So just recently, for seemingly no reason whatsoever, everytime I try to play an online game I have a ridiculous number of lag spikes. I have 110 mb/s down, and 15 mb/s up, 0% packet loss, and very low ping, so any help would be much appreciated. My computer is tethered to another computer's connection, and they're both wirelessly connected to a Netgear Nighthawk.
