![]() ![]() Since they do not require any batteries, they can be used for long periods without having to recharge. They are often used in conjunction with laptops and PCs, and are powered by a USB port. Wireless modems, on the other hand, use mobile telephone lines to transmit data. A router allows data to be shared with multiple devices, provides a static IP address for security and remote access, and more. Hardware modems work in conjunction with a router to distribute data in multiple ways, including a wireless connection. Software modems are the most common, and they work by converting digital data from an ISP into analog data which travels through a cable to a computer. There are two types of modems: software and hardware. Unless you have a dedicated network, you should stick with a router. This is essentially your internet address. The router provides the same external IP address, which your ISP assigns to each device. A router provides a local IP address that connected devices can use. A modem plugs into your network infrastructure, and a router connects the two. While they both work the same way, some people may want to consider getting a router instead of a modem if you only need one device to connect to the internet.Ī router and modem work together to create a network. The connection between your home and your ISP is called a wide area network, and each modem has a public IP address. A modem can then translate the signals from your ISP to your local devices. Modems and routers: How they work togetherĪ modem is a device that connects your home to your internet service provider, usually through coax cable. ![]() In this article, we’ll explain the differences between routers and modems and why you may need one or the other. Both connect to your broadband connection to send and receive data, but modems use different technologies and function differently. These two devices look similar, even with their blinking lights, and operate differently. These multi-functional machines, like Xfinity’s Wireless Gateways, provide all the power you need to read your emails, stream your shows, and connect with your smart devices (without the hassle of dealing with two separate devices).While many people use the terms modem and router interchangeably, it’s important to understand the difference between the two. However, with today’s technology, you don't need a separate modem and separate router necessarily, as new combination modem and router units merge the two devices’ functions into one powerful gadget. Routers and modems have traditionally been two separate devices that worked together to form your home network. Remember that the modem is your network’s translator, while the router is more like an air-traffic controller, communicating with the “planes,” keeping order, and making sure everyone is safe. Creates a firewall to prevent security breaches.Assigns a local IP address to each device on the network.You can choose to create a LAN without Internet access. However, a router doesn’t need to connect to a modem to function. The router manages all the information going to and from each device and the modem and makes sure it all ends up safely in the right spot. ![]() The router creates a local area network (LAN) within your house, allowing your devices to share files and peripherals like printers. The router connects to your modem and then to your devices (laptops, smart TVs, printers, etc.) via either an Ethernet cable or, in the case of a wireless router, WiFi signal. ![]() Routers bring the Internet to your devicesĪ router connects your devices to each other and, in hard-wired connection setups, to the modem. Each modem has an assigned public IP address that identifies it on the Internet. The connection between your house and the Internet is known as a wide area network (WAN). The modem takes signals from your ISP and translates them into signals your local devices can use, and vice versa. Short take: what’s the difference between a modem and a router?Ī modem is a device that connects your home, usually through a coax cable connection, to your Internet service provider (ISP), like Xfinity. Knowing how the blinking boxes plugged into your wall work can help you to get the Internet up and running again the next time there’s a power outage or connection disruption. Can you tell the difference between a modem and router? Have you ever asked, "do I need a modem and router?" To put it simply, the modem connects your home to the Internet, while a router creates the network inside your house. Most people use their home network to access the Internet, but many have no idea how these networks work. ![]()
