Router vs. Modem vs. Gateway: What’s The Difference?

Modems connect your home to the world wide web, also known as the global internet. With it, you can access the internet from home.

That might work for some people, especially if they only need to connect one device to the internet. To connect more than one device or to connect your device(s) wirelessly to the internet.

Solid red lights indicate that you have picked up a broadband signal, but there is no internet connection. The presence of a blinking red light, in contrast to no connection at all, may indicate an unstable connection.
