The modem connects you to the Internet via ISP.
Without a modem, your router will only allow you to connect to a LAN.
If you want to go wireless you need a router.
A router is a networking device through which you share modem’s internet connection with all your devices.
Do I need a modem and a router?
The router sits in between your Internet connection and your local network. But you can’t connect directly to the Internet with just a router. Instead, your router must be plugged into a device that can transmit your digital traffic over whatever type of Internet connection you have. And that device is a modem.
Do I need a router?
Every device on the Internet needs a unique IP address. Your ISP provides you with one, allowing one device to access the Internet. A router will access the Internet through that IP address, then provide local IP addresses–not visible on the Internet–for the PCs and other devices connected to it.
What is difference between modem and router?
The difference between a modem and a router is simple: a modem connects you to the internet, while a router connects your devices to Wi-Fi. It’s easy to get the two devices mixed up if your Internet Service Provider (ISP) rents both to you as part of your internet package.
Do you need an Internet provider to use a wireless router?
Depending on your internet service provider (ISP), you may need to buy a router, a router and separate modem, or a router-modem. Nearly all ISPs use either DSL or fiber for their service, which requires signal conversion by a modem. Most modern routers have modems built-in, so you only need one device.
