A solid router is the centerpiece of the home network. As our lives get more and more digital, multiple devices and increasing bandwidth requirements all push the router, network, and internet connection to their limits. When it comes to PC gaming, this means the router is frequently under heavy load to deliver bleeding edge performance. The best gaming router is one that can cope not only with our current performance needs, but also the future demands of 4K video, Twitch streaming, VR, and the like.

The main feature that a gaming router needs to include is Quality of Service settings (QoS). This helps prioritize gaming traffic over other content, ensuring low latency during game play. This becomes even more critical when other people on the network are simultaneously consuming bandwidth, such as streaming videos or downloading game files.
