Having a good router at home is becoming increasingly important. It's not just about connecting your phone and your computer to Wi-Fi anymore. Nowadays, you need a good router to maximize your internet speeds and connect all your smart home devices and other connected things. But not all Wi-Fi routers are good. In fact, plenty of them won't give you fast internet or a stable connection.
There are a few things to consider when you’re buying a Wi-Fi router. For starters, you’ll want to think about the standards that the router is capable of handling. Most new routers use the 802.11ac standard, which is capable of faster wireless speeds than other routers. If your ISP offers speeds of 100Mbps or more, routers with the 802.11am standard will be able to handle it.
Another thing to consider is whether your router is single band or dual band. The two bands are 2.4GHz and 5GHz, and 5GHz connections are typically faster and more reliable. Some routers offer both bands separately or both bands combined. Dual-band routers are also typically better in high-density areas.
You’ll also want to think about the range of a router, especially if you live in a larger home. Often, you’ll experience dead spots in your home with some routers, but those can be eliminated through the use of a router with a big range, or by using a mesh system, which basically connects multiple routers together to extend the range of Wi-Fi in your house. -Article from Business Insider
