How do modems work? A modem transforms digital information from your computer into analogue signals that can be transmitted over wires. The situation gets more complicated if you are using DSL or fiber connections and if you also get your phone service from your ISP.

However, this is only possible if you are using cable internet. Users can also save money on their monthly internet bills if they buy their modem and router instead of using the ones offered by your ISP. If you want to add more devices to your network or just simply want to take advantage of the latest improvements in Wi-Fi technology, you have to buy a new router if your old router is unable to manage all that. On the other hand, you may have to replace a router more frequently compared to your modem if you want better internet coverage throughout your home. This is possible as modem technology changes slowly. Typically, you can use a modem for years until it gets damaged. It is always better to use a separate modem and router for various reasons.

How is a modem different from a router? A modem connects your home network to the wider Internet, whereas a router allows your wired and wireless devices to use that Internet connection simultaneously while communicating with each other without using the Internet. To make things simpler, here we will discuss some of the key differences between a modem and a router. Although, you need both the devices (maybe integrated or not) to get an Internet connection for all the devices in your home. This means, not all modems include routers and not all routers have modems. However, they are different technologies and have separate functionalities. In most cases, internet service providers (ISPs) give a single box that serves as both a modem and a router. Most users tend to get confused between a modem and a router while discussing their home internet connection.
