Modem settings in the GUI

A GUI? What is that? It sounds like "gooey" and stands for "graphical user interface." It's a tech term for the secure website where you can manage your modem settings.

Learn more about what you can do in the modem GUI and how to use it.

These instructions are for the following modems:

C4000

How to sign in to the modem GUI

Follow the steps below to open and sign in to the secure site.

Two points about signing in to the GUI

1. You must be connected to your Quantum Fiber network to access the GUI site. The GUI site will not load on another network. 


2. Your browser may flag the GUI URL as a security risk because it starts with http (not https). Rest assured, it is safe and you can proceed through the warning.

1.  On a computer or tablet that is connected to your Quantum Fiber network, open a web browser and type http://192.168.0.1 into the address bar.

Entering the URL for the modem settings interface

2.  Sign in to the secure user settings (GUI) with your Admin Username and Password. These are printed on the sticker found on the side of your modem. These are different from your WiFi network name (SSID) and password (key).

Overview of the modem settings menu

Quick Setup provides a place to enter setup credentials, if needed, when first installing and activating your modem. The PPP username and password are needed to connect to the Quantum Fiber network and get internet access. In many cases, these are preset before you receive your modem. If you are resetting a modem or need to reenter these for any reason, you can chat with our support agents for assistance.

The wireless settings control your WiFi network. You can control the 2.4 GHz and 5 GHz options separately.
