Do I need both a modem and a wireless router?
Yes, if you want to connect to the internet wirelessly and have multiple devices access the internet at the same time. A modem connects to your Internet Service Provider (ISP) and converts the incoming signal into data that your devices can use. Without a modem, you won’t be able to connect to the internet at all.
The wireless router then allows multiple devices, such as laptops, smartphones, and smart TVs, to connect to that internet connection over Wi-Fi. Some devices combine both a modem and a router, which can simplify your setup but may limit your options for upgrading either component separately.
What is the difference between a modem and a router?
A modem serves as the gateway between your home network and your ISP. It receives data from your ISP and translates it into a format that can be used by your devices. Modems typically have a single Ethernet port that connects directly to a router or a computer.
In contrast, a router’s primary function is to direct traffic between devices on your home network and the modem. It enables multiple devices to connect to the internet simultaneously, either through Ethernet cables or wirelessly. The router assigns local IP addresses to each device and manages the data flow among them.
