A router provides wireless internet or a wired connection in your home or office. With a router, you can connect computers, TVs, tablets, and smartphones to the network. This way, you can stream movies, download, or surf the web wherever you are. When buying a router, there are a couple of things that you have to keep in mind. If you want to have coverage in the entire home, opt for a router with mesh WiFi. Do you want to use the network to stream 4K movies, opt for a router with a high speed. If you want to connect wired devices, you should take a look at the number of network ports. Expand your network with multiple routers and accessories such as switches, powerlines, or access points.
