A router provides wireless internet or a wired connection in your home or office. With a router, you can connect all your devices to the network. If you want to have coverage in the entire home, opt for a router with mesh WiFi. If you want to use the network to stream 4K movies, get a WiFi 6E or WiFi 7 router. If you want to connect wired devices, you should take a look at the number of network ports. Expand your network with more mesh stations and accessories such as switches, powerlines, or access points.
