I've had an issue for the longest time but only just starting to get annoyed at it due to me playing FPS games which require a stable connection with no hiccups. My problem is a lag spike lasting 1 second, every 30 or so seconds. For example I'm sitting at a solid 30 ping then for a second it will jump to 120, in-game this obviously jolts you and its becoming pretty unplayable.
Any tips to resolve this issue would be greatly appreciated!!
