Hard restart at least once a day to clear the cache or even if you're changing games, because the previous game will still be using up resources in the background. Also, make sure you are hard wired, not on wifi. Wifi is not and never will be as stable as a cable. I don't care about how kids these days insist WiFi is "just as good". It is not "just as good" for online gaming. Every long time gamer knows this and if they are serious about having the best connection they work to reduce bottlenecks, but a large amount of console gamers don't know this because compared to serious PC gamers they are casuals who believe in myths like lag switches and the myth that someone else's lag makes them better in pvp.
