Are you struggling to set up a static IP on your Comcast Business Class modem to router? You're not alone. Many users face difficulties in configuring their modem and router to achieve a static IP. In this article, we will guide you through the step-by-step process of setting up a static IP on your Comcast Business Class modem to router.

Understanding Static IP

A static IP is a fixed IP address assigned to your device or network. Unlike dynamic IP, which changes every time you connect to the internet, a static IP remains the same. This is particularly useful for businesses, online gaming, and applications that require a consistent IP address.

Equipment Requirements

To set up a static IP on your Comcast Business Class modem to router, you will need the following equipment:

Comcast Business Class Modem/Router: This is the modem provided by Comcast for business use. It has a built-in router and supports static IP configuration.
Router: You will need a separate router to connect to the Comcast Business Class modem. This router will be used to distribute the static IP to your devices.
Computer or Device: You will need a computer or device to access the modem and router settings.

Step 1: Accessing the Comcast Business Class Modem Settings

To access the Comcast Business Class modem settings, follow these steps:

Connect to the Modem: Connect your computer or device to the Comcast Business Class modem using an Ethernet cable.
