How to Add Extra Ethernet Ports to Your Router [2025]

Running out of Ethernet ports on your router can be frustrating. But you don't need to rush out and buy a new router just yet. The solution is simpler and more affordable: adding an Ethernet switch. This guide will walk you through everything you need to know, from choosing the right switch to setting it up.

TL; DR

Use Ethernet switches: Easily expand your network with a switch.
Installation is simple: Plug it into your existing router.
Choose the right model: Consider number of ports and speed requirements.
Avoid common pitfalls: Ensure compatibility and correct configuration.
Plan for the future: Opt for models that can support network growth.

Speed is the most crucial feature when selecting an Ethernet switch, followed by the number of ports. PoE is also important but less critical. Estimated data based on typical considerations.

Why You Might Need More Ethernet Ports

With more devices connecting to the internet than ever before—like smart TVs, gaming consoles, and home office equipment—your router's limited Ethernet ports might not suffice. According to a Fortune Business Insights report, the demand for Wi-Fi chipsets is rising, indicating a surge in connected devices.

The Rise of Connected Devices

The average household now has dozens of devices connecting to the internet. From IoT gadgets to high-bandwidth gaming consoles, the demand for stable connections is at an all-time high. Wired connections offer stability and reduced latency, which is crucial for activities like streaming and online gaming. BGR highlights the importance of future-proof smart home devices in maintaining a seamless internet experience.

Introducing Ethernet Switches

An Ethernet switch is a device that expands your network's capacity by adding more ports. Unlike hubs, switches are smarter—they can efficiently manage data traffic, ensuring each connected device gets the bandwidth it needs. How-To Geek explains how a simple switch can alleviate network congestion.

What is an Ethernet Switch?

An Ethernet switch connects to your router and adds more ports, allowing more devices to join your network. The switch manages data packets intelligently, ensuring efficient data flow. Tom's Hardware provides insights into affordable options for upgrading your network with a switch.

Ethernet Switch: A device that adds more Ethernet ports to your network, managing data packets to ensure efficient traffic flow between devices.

Types of Ethernet Switches

There are mainly two types of Ethernet switches:

Unmanaged Switches: Simple plug-and-play devices, ideal for home use.
Managed Switches: Offer advanced features like VLAN support and bandwidth control—better suited for businesses.

Key Considerations for Ethernet Switches

Choosing the right Ethernet switch involves considering factors like the number of ports and future growth potential. Estimated data.

Choosing the Right Ethernet Switch

When selecting a switch, consider the following:

Number of Ports: Choose based on current needs and future expansion.
Speed: Ensure the switch supports your required data transfer speed (e.g., Gigabit Ethernet). How-To Geek discusses the benefits of investing in higher-speed switches.
Power over Ethernet (PoE): Useful for powering devices like IP cameras directly through Ethernet cables.

Best Practices for Installation

Ensure Compatibility: Match port speeds (e.g., Gigabit) with your router.
Cable Management: Use cable ties and labels to keep your setup organized.
Update Firmware: Check for firmware updates on managed switches for improved security and features.
