A router connects your personal computing devices (laptop, printer, tablet, game console, phone) to the Internet and transfers data among computing devices in a home or office network.
When shopping for a router, consider whether you want one that's wired or wireless. A wired router offers a dedicated connection with no interference and higher security than a wireless router. On the other hand, with a wireless router you can connect to the Internet anywhere with a signal, without being tethered to a physical cable. This lets you connect more devices, since you aren't limited by the number of ports on the router. You can also connect a smartphone or tablet, make free calls with mobile apps on wireless devices and allow guests to connect to your Wi-Fi.
If you choose to buy a Wi-Fi router, you'll have a choice between a single-band and a dual-band router. Dual-band routers, which are 2.5 GHz, have a longer range and go through walls, but household appliances like your phone or garage door opener can cause interference. Single-band routers, which are 5 GHz, have a shorter range, but they have a more powerful signal and carry more data. Not all devices accept a 5 GHz signal, so check yours for compatibility.
