Why Use an Ethernet Cable With a Wireless Router?

Before we dive into how to connect ethernet cable to wireless router, it’s important to know why Ethernet cables still matter even in a wireless world.

1. Faster & More Stable Speeds

An Ethernet connection provides:

Consistent data flow

No interference

Lower latency

Better streaming and gaming performance

2. More Security

Wired connections are harder to intercept compared to WiFi, making them ideal for:

Work-from-home users

Online banking

IoT device setup

3. Perfect for Routers, Modems & Secondary Devices

Ethernet cables ensure:

Proper signal transfer between modem and router

Smooth communication with smart TVs, PCs, consoles, etc.

Things to Check Before Connecting Your Ethernet Cable

Setting up the cable is easy, but you must check a few details first.

1. Inspect the Cable

Ensure your LAN/Ethernet cable:

Has no cuts or bends

Isn’t loose at the connectors

Is at least Cat5e or Cat6 for best performance

2. Identify the Correct Ports

You’ll see two types of ports on your router:

WAN/Internet (usually blue) — For modem to router

LAN ports (usually yellow) — For computers, TVs, etc.

If you’re unsure about how to plug ethernet cable into router for internet, always use the WAN port for the modem-to-router connection.

3. Restart Your Devices

Before connecting, restart:

Modem

Router

PC or laptop

A fresh start prevents sync issues.

Step-by-Step Guide: How to Connect Ethernet Cable to Wireless Router

Now let’s get into the actual setup. These steps work for any brand—TP-Link, Netgear, D-Link, Asus, Huawei, or any ISP-provided router.

Step 1: Turn Off the Modem and Router

This prevents electrical surges and ensures a clean handshake between devices.

Step 2: Connect Ethernet Cable From Modem to Router

Here’s the most important step in making ethernet connection with wireless router:

Plug one end of the Ethernet cable into the modem’s LAN port

Plug the other end into the router’s WAN/Internet port

This is the core action of how to connect ethernet cable to modem and router together.

Step 3: Power On the Modem, Then Router

Wait for:

Modem lights to turn stable

Router’s WAN and LAN lights to start blinking

Blinking means data flow is active.

Step 4: Connect Devices Using LAN Ports

If you want to connect your PC, TV, or gaming console:

Use any LAN port (1, 2, 3, 4) on the router

Plug in the Ethernet cable firmly until you hear a click

This is exactly how to connect LAN cable to WiFi router properly.

Step 5: Test Your Internet Connection

Use:

Speedtest

YouTube

Router admin panel

If the speeds are consistent, your setup is correct.

Common Mistakes to Avoid

Even when people know how to connect ethernet cable to wireless router, these errors can still cause issues:

1. Using Damaged Cables

Frayed or broken cables may work intermittently or not at all.

2. Confusing WAN and LAN Ports

If your router doesn’t get internet, double-check you used the WAN port.

3. Not Restarting the Modem

Most modems must reset to detect a new router.

4. Using Very Old Ethernet Cables

Older Cat3 or Cat5 cables can throttle your speed dramatically.

Google DNS: 8.8.8.8

4. Enable QoS

Prioritize gaming or Zoom calls.

FAQs (Frequently Asked Questions)

1. Can I use any Ethernet cable to connect my modem and router?

Yes, but Cat5e or Cat6 is recommended for stable high-speed performance.

2. Why is my Ethernet connection not working even after plugging in?

Check:

Cable damage

Loose connectors

Correct use of WAN/LAN ports

Whether the modem was restarted

3. How to connect Ethernet cable properly to router without loose connection?

Push the connector until you hear a clear click. If it doesn’t click, replace the cable.
