How to Connect Two Ethernet Cables Together?

In the digital age, we’re accustomed to the convenience of wireless connections. Wi-Fi has become a staple in our daily lives, enabling us to browse the web, stream media, and work remotely without the constraints of physical wires. However, when it comes to reliable, high-speed data transfer, nothing beats a good old Ethernet cable.

Ethernet cables provide a direct data flow, offering superior speed and stability compared to Wi-Fi. This makes them the preferred choice for gamers, programmers, and anyone else who relies on a fast, stable internet connection. But what happens when your Ethernet cable isn’t long enough to reach your workspace or gaming station? Do you compromise and switch back to the unpredictable realm of Wi-Fi? Not necessarily. The solution is simpler than you might think: connect two Ethernet cables together.

The Need for Longer Ethernet Cables

Whether you’re setting up a home office, a gaming station, or a home theater system, you might find that your Ethernet cable falls short—literally. Perhaps it doesn’t reach your favorite armchair, or maybe it’s just a few feet shy of your new gaming console. In such cases, you might feel tempted to revert to Wi-Fi, but as we’ve established, this could mean compromising on speed and stability.

So, what’s the solution? You can extend your network cable connection by connecting two Ethernet cables together. This simple solution can save you the trouble and expense of running a new, longer cable from your router or switch to your device.

Connecting Two Ethernet Cables: The Ethernet Coupler

The easiest way to connect two Ethernet cables is to use an Ethernet coupler. This small, inexpensive device can solve your connectivity problems in no time. Here’s how it works:

  1. Purchase an Ethernet coupler: Ethernet couplers are readily available online or at your local electronics store. They’re affordable and come in handy for various networking needs.
  2. Plug in the cables: The Ethernet coupler has two provisions for Ethernet cables—one on each end. Take the first cable and plug it into one of the provisions. You’ll hear a reassuring click when it’s correctly plugged in. Then, plug the second cable into the other provision.

And that’s it! You’ve successfully extended your Ethernet cable connection. Now, you can enjoy a stable, high-speed internet connection in your desired location.

Unplugging the Ethernet Cables from the Coupler

If you need to use the Ethernet cables separately at times, you can easily unplug them from the coupler. Here’s how:

  1. Press and pull: You’ll notice a small part of the Ethernet cable protruding from the coupler. Simply press this part slightly and pull the cable out.
  2. Repeat for the other cable: If you want to unplug the other cable as well, follow the same process.

Now, you can use the cables separately as needed.

Other Methods of Connecting Ethernet Cables

While using an Ethernet coupler is the most straightforward method, there are other ways to connect two Ethernet cables. For instance, you can wire both sides with a standard RJ45 male connector and then add a female/female coupler. This method, while slightly more complex, can also effectively extend your Ethernet cable connection.

Considerations When Connecting Ethernet Cables

While connecting two Ethernet cables can solve the problem of a short cable, it’s important to note that using multiple couplers can start to degrade the signal. Therefore, it’s always better to use a single, longer cable when possible. If you must use multiple cables and couplers, try to keep the total length of the cable run under 100 meters (328 feet) to avoid potential signal degradation.

The plastic material is fire-resistant and impact-resistant, making it a durable choice for your networking needs.

People Also Ask

Can You Splice Two Ethernet Cables Together?

Yes, you can splice two Ethernet cables together. However, it’s not the most recommended method as it can lead to signal degradation and potential connectivity issues. If you must splice cables, make sure to carefully match the color-coded wires and use a quality splice connector.

How Do I Connect Two Ethernet Cables to One Port?

To connect two Ethernet cables to one port, you would need a network switch or a router with multiple Ethernet ports. Simply plug each cable into a separate port on the switch or router.

What Happens When You Connect Two Ethernet Cables?

When you connect two Ethernet cables, you essentially extend the length of the cable. This allows you to reach further distances with your wired network connection. However, remember that longer cable runs can potentially degrade the signal, especially if they exceed the recommended maximum length of 100 meters.

How Do You Connect Cat6 Cables Together?

To connect two Cat6 cables together, you can use an Ethernet coupler or a patch panel. Both methods allow you to extend the length of your Cat6 cable. When using a coupler, make sure it’s rated for Cat6 or higher to maintain the full performance capabilities of your cables.


In conclusion, connecting two Ethernet cables together is a simple and effective solution when your cable isn’t long enough. Whether you’re a gamer, a programmer, or just someone who enjoys a fast, stable internet connection, this method can help you extend your wired network to your desired location. So, don’t let a short Ethernet cable limit your connectivity—just connect two cables together and enjoy the speed and stability of a wired connection.
