Do you need modem and router9/25/2023 The router directs each packet it receives, whether from your device or from your modem, and sends it on the most efficient possible route to its destination. Routers are often compared to air traffic controllers and their role to direct traffic in the most efficient way possible. By forwarding packets of data between computer networks to its destination IP address, the router manages all the information going to and from each device and the modem and makes sure it all ends up going to its intended recipients. The router creates a local area network (LAN) in your home, connecting the devices in your house to each other. A router connects your devices to each other and to the modem using either an Ethernet cable or Wi-Fi signal. Your router is the bridge between your computer and your modem. Routers Connect Your Devices to Your Home’s Internet Connection If you haven't already, you can read more about how to troubleshoot your modem on our blog. Each modem in a WAN has a public IP address that identifies it on the Internet. This network is provided and serviced by your Internet provider. Your home’s connection to the Internet is part of a much larger network covering a large geographic area, known as a wide area network (WAN). It also does the opposite, receiving digital signals that you are sending out and translating them into analog signals that can be transmitted to your Internet service provider. It receives analog signals from your provider and translates them into digital signals your computer and devices can use. The word “modem” is short for “modulator-demodulator.” This is because a modem’s main function is to convert digital signals to analog and back again. Your Internet service provider can’t communicate directly to your computer, so your modem bridges that gap and connects your household to your Internet service provider. The differnece between a router and modem is similar to the difference between Wi-Fi and Internet one connects you to a small network that exists within your own home, and the other connects you to a large network that spans multiple communities including your own. But how much do you know about each device, what it’s used for, and the unique role it plays in connecting you to the Internet?īoth devices’ roles, methods for bringing you your service, and troubleshooting processes are easier to learn than you think. You know that you typically use both to go online. If you get Internet to your home, there’s a chance you’ve heard the words “modem” and “router” often.
