ExtremeTech takes a look at how you can optimize your router for gaming, you can check it out over here.
Modern games, operating systems, and routers are a lot friendlier than they used to be. For the most part, as long as your roommate doesn't leave BitTorrent running or try to stream high bitrate audio or video, the games will work. Just click the button to "allow access" when the game pops up the Windows Firewall (or whatever firewall you have installed) the first time and you should be good to go. Right?
Well, not always. Home networking can still be a headache, and for performance-critical apps like gaming and VOIP, doubly so. These tips will help you decide which router to use for gaming and how to configure it to get the highest performance and least trouble from your games.
