If you use the internet, you probably do so through a router. Routers don’t directly connect to the internet – that’s what modems are for – but routers are still a crucial part of many household networks because they act as communication hubs. With any of the best Wi-Fi routers, you can set up your computer anywhere in the house, play multiplayer t**les on your Xbox Series X, and turn on lights with your phone. While routers make life far more convenient, like many other modern electronics, you should update their firmware to keep them running smoothly.
