When it comes to setting up a home network, many of us are left scratching our heads, wondering which cord goes where. One of the most common questions asked is, “Where does the yellow plug go in a router?” It’s a simple question, but one that can be frustratingly difficult to answer, especially for those who are new to the world of networking. In this article, we’ll delve into the world of routers and Ethernet cables, exploring the different types of cables, what they do, and, of course, where that yellow plug goes.
Understanding Ethernet Cables
Before we dive into the world of routers, it’s essential to understand the basics of Ethernet cables. Ethernet cables are used to connect devices to a local area network (LAN) or wide area network (WAN). They come in various types, each with its own unique characteristics and uses.
Cat5, Cat5e, and Cat6: What’s the Difference?
You may have seen Ethernet cables labeled as Cat5, Cat5e, or Cat6. These labels refer to the category or type of cable. The main difference between these categories is the speed and frequency at which they can transmit data.
- Cat5: Category 5 cables are the oldest and slowest type of Ethernet cable. They have a maximum bandwidth of 1Gbps and are only suitable for slower networks.
- Cat5e: Category 5e cables are an enhanced version of Cat5 cables. They have a maximum bandwidth of 1Gbps and are suitable for most home networks.
- Cat6: Category 6 cables are the fastest and most advanced type of Ethernet cable. They have a maximum bandwidth of 10Gbps and are suitable for high-speed networks.
What’s with the Colors?
Ethernet cables are made up of four twisted pairs of wires, each with a different color. The colors of the wires are:
- Blue: The blue wires are used for RX (receive) data transmission.
- Green: The green wires are used for TX (transmit) data transmission.
- Yellow: The yellow wires are used for RX (receive) data transmission.
- Brown: The brown wires are used for TX (transmit) data transmission.
The Anatomy of a Router
Now that we’ve covered the basics of Ethernet cables, let’s move on to routers. A router is a device that connects multiple devices to the internet and allows them to communicate with each other. Routers typically have several ports, including:
- WAN (Internet) Port: This port is used to connect the router to the internet via a modem.
- LAN Ports: These ports are used to connect devices to the router using Ethernet cables.
- Wireless Antennas: These are used to transmit and receive wireless signals.
The Yellow Plug: Where Does it Go?
Now, finally, we get to the question at hand: where does the yellow plug go in a router? The answer is simple: the yellow plug goes into a LAN port on the router.
But which LAN port? That’s a good question. The truth is, it doesn’t matter which LAN port you use. All LAN ports on a router are identical and can be used to connect devices using Ethernet cables.
Common Scenarios: Where to Plug in Your Ethernet Cables
Now that we’ve covered the basics of Ethernet cables and routers, let’s explore some common scenarios and where to plug in your Ethernet cables.
Scenario 1: Connecting a Computer to a Router
In this scenario, you want to connect a computer to a router using an Ethernet cable. To do this, simply plug the yellow plug into a LAN port on the router and the other end into the Ethernet port on your computer.
Scenario 2: Connecting a Switch to a Router
In this scenario, you want to connect a switch to a router using an Ethernet cable. A switch is a device that allows you to connect multiple devices to a single Ethernet port on a router. To do this, plug the yellow plug into a LAN port on the router and the other end into the uplink port on the switch.
Scenario 3: Connecting a Modem to a Router
In this scenario, you want to connect a modem to a router using an Ethernet cable. To do this, plug the yellow plug into the WAN (Internet) port on the router and the other end into the Ethernet port on the modem.
Troubleshooting Common Issues
Sometimes, even with the best intentions, things can go wrong. Here are some common issues you may encounter when working with Ethernet cables and routers:
Issue 1: No Internet Connection
If you’re not getting an internet connection, check that the yellow plug is securely plugged into the WAN (Internet) port on the router and the other end is securely plugged into the Ethernet port on the modem.
Issue 2: Slow Network Speeds
If you’re experiencing slow network speeds, check that you’re using a high-quality Ethernet cable and that it’s not damaged. Also, ensure that your router is configured to use the correct network settings.
Conclusion
In conclusion, the yellow plug in an Ethernet cable is used to connect devices to a router using a LAN port. It’s essential to understand the basics of Ethernet cables and routers to ensure that your home network is set up correctly. By following the scenarios outlined in this article, you should be able to connect your devices to your router with ease.

What is the yellow plug on my router?
The yellow plug on your router is an Ethernet port, also known as an RJ-45 port. It’s used to connect devices to your router using Ethernet cables, which are common in offices, homes, and other networks. This port is typically yellow in color, hence the name, but it can also be blue or other colors depending on the router model.
The yellow plug is designed to transfer data at high speeds and provide a reliable connection. It’s often used to connect devices that require a stable and fast internet connection, such as gaming consoles, smart TVs, and computers.
What is the difference between the yellow plug and other Ethernet ports?
The main difference between the yellow plug and other Ethernet ports is its purpose. The yellow plug is usually designated as the “uplink” or “WAN” (Wide Area Network) port, which connects your router to a modem or another router. This port is meant to receive the internet signal from your internet service provider (ISP) and broadcast it to other devices on your network.
In contrast, the other Ethernet ports on your router are typically labeled as “LAN” (Local Area Network) ports, which connect devices to your local network. These ports are used to create a local network, allowing devices to communicate with each other and share resources.
Can I use the yellow plug to connect my computer to the router?
Technically, you can use the yellow plug to connect your computer to the router, but it’s not recommended. The yellow plug is designed for uplinking to a modem or another router, and using it to connect a device can cause confusion and instability in your network.
Instead, use one of the other Ethernet ports on your router to connect your computer. These ports are designed for LAN connections and will provide a stable and fast connection to your network.
What happens if I connect the yellow plug to the wrong device?
If you connect the yellow plug to the wrong device, such as a computer or another router, it can cause network conflicts and instability. This can lead to slow internet speeds, dropped connections, and even damage to your devices.
In some cases, connecting the yellow plug to the wrong device can also create a “network loop,” where the signal is sent back to the router, causing a feedback loop that can crash your network. To avoid these problems, make sure to connect the yellow plug to the correct device, such as a modem or another router.
Can I use a crossover cable with the yellow plug?
No, you should not use a crossover cable with the yellow plug. Crossover cables are used to connect two devices of the same type, such as two computers or two routers, without the need for a switch or hub.
The yellow plug is designed to connect to a modem or another router, which requires a straight-through Ethernet cable. Using a crossover cable can cause network conflicts and instability, and may even damage your devices. Always use a straight-through Ethernet cable when connecting the yellow plug to a modem or another router.
Why do some routers have multiple yellow plugs?
Some routers have multiple yellow plugs to provide more flexibility and connectivity options. For example, a router with two yellow plugs can connect to two separate modems or internet connections, providing redundancy and failover capabilities.
In other cases, multiple yellow plugs may be used to connect to multiple networks or subnets, allowing for more complex network configurations. However, in most cases, a single yellow plug is sufficient for connecting to a modem or another router.
Can I disable the yellow plug on my router?
Yes, you can disable the yellow plug on your router if you’re not using it. This can be done through the router’s web interface or configuration menu. Disabling the yellow plug can improve network security and reduce the risk of unauthorized access to your network.
However, be careful when disabling the yellow plug, as it may affect your internet connection or other network devices. Make sure you understand the implications of disabling the yellow plug before making any changes to your router’s configuration.
