This type of connection offers several advantages over wireless connections, such as enhanced security, speed, and dependability.

With the right equipment, including Ethernet cables, switches or routers, and adapters, you can experience a seamless and reliable connection that will leave you wondering how you ever managed without it.

As we proceed through this guide, we’ll discuss the benefits of wired internet, the essential equipment needed for setup, and a step-by-step guide to installing and optimizing your very own hard-wired network. So, are you ready to make the switch and experience the difference?

Advantages of a Hard-Wired Connection


One of the primary advantages of a hard-wired connection is its speed. With a direct connection through an Ethernet cable, you can experience faster and more consistent internet speeds than with a wireless connection.

This improvement in speed is especially noticeable when downloading or streaming large files and during online gaming.


Hard-wired connections also offer greater reliability than wireless networks. With wireless connections, you’re more likely to experience signal drops, interference, and other issues that can disrupt your internet access.

In contrast, hard-wired connections provide a stable and reliable connection, ensuring that you can enjoy uninterrupted internet access at all times.

Reduced EMF Exposure

Furthermore, hard-wired connections reduce the exposure to electromagnetic field (EMF) radiation, which can be harmful to health when emitted by WiFi or Bluetooth devices.

To fully reap the benefits of hard-wired connection, it’s important to disable WiFi connections and Bluetooth on your devices after installation.

This not only minimizes RF Radiation levels in inhabited areas, but also ensures that your devices are utilizing the faster and more secure hard-wired connection.

Essential Equipment for Cable Internet

Essential Equipment for Cable Internet

Before delving into the details of setting up your cable internet, it’s crucial to familiarize yourself with the essential equipment required for the process. This includes Ethernet cables, switches or routers, and the appropriate adapters for your devices.

In the following subsections, we’ll provide insights on selecting the right Ethernet cable, choosing an Ethernet switch or router based on your needs, and using adapters for various devices.

Choosing the Right Ethernet Cable

Ethernet cables come in various types, such as Cat5e, Cat6 and Cat7, and choosing the right one for your needs is essential for optimal performance.

Factors to consider when selecting an Ethernet cable include the type of cable, the length required, and the speed requirements for your devices. Shielded Ethernet cables are recommended, as they provide a connection with no electromagnetic field.

These cables can be easily acquired on Amazon or at local electronics stores. Remember, investing in high-quality Ethernet cables is crucial for ensuring a stable and reliable internet connection, so make sure to choose wisely.

Selecting an Ethernet Switch or Router

An Ethernet switch is a device that facilitates the transmission of an internet signal through Ethernet cables connected to it.

When selecting an Ethernet switch or router, it’s important to consider the number of ports needed, based on the number of devices you wish to connect to the internet and the rooms requiring internet access.

One port should be subtracted from the total number needed, as it will be used for the connection to the modem.

To connect an Ethernet switch to a modem, simply use a short Ethernet cable (usually provided with the modem) to connect the modem’s designated port to the initial port on the switch.

By properly assessing your needs and selecting a switch or router with the appropriate number of ports, you can ensure a smooth and efficient setup.

Adapters for Wired Internet on Various Devices

Adapters play a crucial role in connecting various devices to your hard-wired internet network.

Powerline adapters, for instance, enable the use of a home’s electrical wiring to transfer data signals, making it easier to hard-wire your home for internet.

To use these adapters, simply plug them into the electrical outlets near your devices and follow the provided instructions.

Another useful device is a wireless repeater, which can be plugged into an outlet near your computer, connected to the WiFi network, and then connected to your computer using an Ethernet cable.

Wireless repeaters typically offer Ethernet ports for added convenience, allowing you to easily connect multiple devices to your hard-wired network.

Step-by-Step Guide to Setting Up a Hard-Wired Internet Connection

Step-by-Step Guide to Setting Up a Hard-Wired Internet Connection

Now that we’ve covered the basics, it’s time to dive into the step-by-step process of setting up your cable internet.

This guide will take you through disabling wireless connectivity, mapping out your network, installing Ethernet cables and ports, and connecting your devices to the wired network.

By following these steps, you’ll be well on your way to enjoying the numerous benefits of cable internet.

1. Disable Wireless Connectivity

The first step in setting up your cable internet is disabling wireless connectivity. This ensures that your devices are using a faster and more secure connection instead of relying on WiFi or Bluetooth signals.

To disable wireless connectivity, turn off your WiFi, Bluetooth, and cellular signals on your devices, and consider using external wired keyboards and mice to further reduce RF radiation exposure.

If you have a 2-in-1 router/modem unit, you may need to disable the WiFi on the unit itself or purchase a separate router to use with your hard-wired connection.

To locate the switch to turn off your WiFi, check the router itself or consult the accompanying documentation. Alternatively, you can unplug the router from the wall to turn off the WiFi signal.

2. Map Out Your Network

The next step is mapping out your network. This involves creating a floor plan for each room in your home and locating the devices that need to be connected to the internet.

Based on this information, you can determine the number of Ethernet ports needed for each room, taking into consideration the number of devices and their locations.

Once you’ve determined the number of ports needed, calculate the overall number of ports necessary to hard-wire Ethernet cables to. This information will be crucial when selecting an Ethernet switch or internet router and purchasing the appropriate amount of Ethernet cables for your setup.

3. Install Ethernet Cables and Ports

With your network mapped out and the necessary equipment on hand, it’s time to install your Ethernet cables and ports.

Route the cables along the baseboards or secure them to the wall or floor, ensuring a neat and organized appearance. Plug one end of the cable into your computer or other device, and the other end into the appropriate Ethernet port on your switch or router.

While you can attempt the installation process yourself, it’s strongly advised to consult with a handyman or electrician to determine the optimal approach. They can provide expert advice on cable routing, internet port installation, and any potential challenges that may arise during the process.

4. Connect Devices to the Wired Network

After installing your Ethernet cables and ports, it’s time to connect your devices to the wired network. Ensure that your devices are properly connected and that all necessary wireless signals (WiFi, Bluetooth, and cellular) are disabled.

If you’re using powerline adapters, be aware that they can potentially provide slower internet speeds than other connection types.

To verify that your devices are properly connected, perform a ping test or check your connection speed.
