Best Practices for Modem

Best practice 1

A modem is the device that links your home or office to the service coming from your internet provider. Its job is different from a router’s job.

In simple terms, the modem handles the connection to the provider, while the router handles traffic inside and out of your local network.

A modem translates between your provider’s line and the networking equipment inside your home or office.

Without a modem or equivalent provider connection device, your router and local devices would not have a path to your internet service.

Best practice 2

Modems matter because they are part of the boundary between your internet provider and your local network.

When people troubleshoot internet outages, the modem is often one of the first devices checked.

A common misconception is that modem and router mean the same thing. They do different jobs, even though many consumer devices combine them in one box.

Another misconception is that a modem provides Wi-Fi by itself. Wi-Fi is usually handled by a router or a combined gateway device.
