Router placement is key. If you’re able to, make sure your router is in the most central place in your house. Whether that means having a tech from your ISP come and relocate your modem or simply picking up an extra-long ethernet cable. Distance isn’t the only consideration, however: Physical barriers — walls, furniture, even people — can diminish your signal and wreak havoc on performance. It’s key to remember that light, sound, and radio signals are all essentially the same thing: electromagnetic waves that carry information at varying wavelengths. If something muffles sound, it will likewise have an effect on Wi-Fi, just to a lesser degree. Make sure there are as few barriers as possible between your router and your chosen gaming device, especially if that gaming device is one of those new Samsung TVs, as televisions tend to have cheap wireless cards, and you want to give it the best fighting chance you can.
