Hi im using usb tethering from my phone to my pc since i dont have wifi. Most of the times it works fine but yesterday it started fluxiating between 40 and 150 ping for no reason. i have no other programs open than the game im playing, my phones windows are all closed and nothing is downloading. I have no idea what could possibly be making me fluxiate in ping since ive tried to find anything close to a download or open program.
