A router is a device that allows multiple devices to share an Internet connection. Routers work together with modems to provide Internet access to devices in your home. Routers also provide a firewall to create a layer of security between your home network and the Internet.
Routers use the single wired Ethernet connection that your modem provides to broadcast a WiFi signal and provide several additional Ethernet connections for wired devices. You can’t use a router by itself; routers require a cable or DSL modem to convert the Internet signal delivered by your Internet service provider (ISP) into an Ethernet connection that you can use to access the Internet. For more information about modems, see What’s a modem?
Router technology is constantly improving along with the introduction of new WiFi standards. Newer WiFi standards usually improve performance for older devices too, so for the fastest speeds and best wireless connection range, you should consider routers that use the latest WiFi standard.
NETGEAR WiFi 6E routers provide the fastest speeds for cutting edge WiFi 6E devices with access to a new 6 GHz wireless band, while NETGEAR WiFi 6 routers deliver optimal performance for new and old devices at a lower price point. NETGEAR Nighthawk Pro Gaming routers offer gaming-focused features to create the best online gaming experience on any platform.
If you don’t want to set up a separate modem and router, you might want to consider a modem router, also known as a gateway. NETGEAR cable modem routers combine modem and router functionality into a single device that optimizes Internet speeds and WiFi performance while helping you save on equipment rental fees.
