How to Connect a Small Business Switch with a Cable Modem?

Posted on Dec 26, 2023 by


Connecting with a cable modem is an essential step in setting up a reliable and fast internet connection. It is the most common method for expanding home and enterprise networks. This article will discuss how to connect a wired modem using a small business switch.

Network Connection

Devices You’ll Need

To establish a connection with a cable modem, you will need the following devices:

Cable modem: It is used to connect to your Internet Service Provider (ISP) and receive an Internet signal. Converts digital signals from your ISP into a format your home network can understand for use on devices around the home.

Switch: An Ethernet switch is commonly referred to as a multi-port network bridge that processes and routes data on a data link layer (layer 2) and sometimes a network layer (layer 3) of the OSI model. An Ethernet switch is an intelligent device that transmits data to specific MAC addresses within the LAN. It can learn and distinguish between specific addresses by accessing them from a CAM table. This device acts as a central hub, allowing multiple devices to connect to the cable modem. The small business switch is designed for homes and small to medium businesses.

Wireless router: It takes information provided by the modem or ONT and routes it to the various devices that are connected. The router uses protocols such as ICMP (Internet Control Message Protocol) to communicate with each other and configures the best route between any two hosts.


Connection Steps

Follow these steps to connect your computer and small business switch to your cable modem:

Step 1: Ensure Safety by Turning off the Power to All Devices

Before starting the connection process, prioritize safety by turning off the power to all devices involved.

Step 2: Connect Your Cables to Devices

Take an Ethernet cable and connect one end to the Ethernet port on the back of your modem. Plug the other end into your router's WAN port.

Step 3: Connect the SMB Switch to the Wireless Router

Using another Ethernet cable, connect one end to an available Ethernet port on the SMB switch. The SMB switch is a device that allows multiple devices to be connected within a local area network (LAN). Next, connect the other end of the cable to one of the LAN (Local Area Network) ports on your wireless router. The LAN ports are typically numbered and separate from the WAN port.

Step 4: Power on the Devices and Check LED Lights

Once the connections are made, proceed to power on the cable modem, SMB switch, and wireless router in the specified order. Then, verify if its LED lights start blinking. If the LED lights are not blinking, double-check the power source connection for the switch. Additionally, ensure that the computers or devices you plan to connect to the network have functioning network adapters.

Step 5: Verify Internet Connection on Your Computer

To confirm a successful connection, check if your computer is successfully connected to the internet. Open a and attempt to load a website. If the website loads without any issues, it indicates that your computer is properly connected to the network and can access the internet.

Connection Steps


Connecting with a cable modem using a small business switch can provide a more efficient networking environment for small businesses. By following the steps outlined in this guide, you can easily establish a connection between your computer, switch, and cable modem. Remember to always power off the devices before making any connections, and power them on in the correct sequence. With a stable connection, you can enjoy a seamless internet experience.
