What Is a Router, Modem, and ISP? (Simple Explanation)

Mr Ricky Mascot as a network engineer holding a laptop

Let’s clear up one of the biggest tech confusions right away—because this one trips up a lot of people.

You’ve got three main players:

  • ISP (Internet Service Provider): The company you pay every month for internet
  • Modem: The device that brings that connection into your building
  • Router: The device that shares it with everything else

Think of it like water:

  • ISP = water company
  • Modem = water line coming into your house
  • Router = pipes that send water to every room

Now here’s the fun part—when things stop working, everyone suddenly becomes an expert in one move:

👉 Unplug the router → wait → plug it back in

And somehow… it works.

That’s not magic—it’s just resetting the traffic flow. But hey, we’re not taking that win away from you.

Internet Acting Up?

That’s one of the most common things we fix.
