Why Connect Ethernet to Your Wireless Router?
WiFi technology has improved tremendously over the years. The latest WiFi 6 and WiFi 6E routers promise multi-gigabit wireless speeds. However, Ethernet still reigns supreme in terms of raw speed and reliability:
- Faster speeds – Ethernet is capable of 1 gigabit per second (Gbps) or higher. WiFi speeds depend on router model, distance, and interference.
- Lower latency – Ethernet has near-instant response times crucial for gaming and video calls. WiFi latency can vary.
- Fewer interruptions – Ethernet offers consistent connectivity without signal drops. WiFi is impacted by distance, obstructions, and network traffic.
- Enhanced security – Wired connections are not vulnerable to signal hacking. WiFi signals can be intercepted by attackers nearby.
Bottom line: While WiFi is convenient, Ethernet is vastly superior for tasks requiring top speed, low latency, or maximum stability.

When to Use Ethernet Over WiFi
Here are some examples where wired Ethernet connections make the most impact:
- Gaming (reduces lag spikes for competitive advantage)
- 4K/8K video streaming (eliminates buffering and artifacts)
- Video calls and conferencing (prevents glitches or freezes)
- Backing up large files (faster transfer speeds)
- Work-from-home setups (dedicated bandwidth for remote sessions)
- Offices with high network usage (each device gets full speeds)
For basic web browsing and lightweight tasks, WiFi is sufficient. But when network performance matters, Ethernet is the way to go.
Step-by-Step Guide to Connect Ethernet Cable
Ready to connect your wireless router to an Ethernet cable? Follow these steps:
1. Gather the Right Equipment
- Ethernet cable – Use Cat5e or Cat6. Both support gigabit Ethernet; Cat6 enables longer distances.
- Wireless router – Virtually all modern routers have Ethernet ports built in. Confirm yours does before proceeding.
- Devices with Ethernet ports – Most PCs, smart TVs, consoles, and printers have Ethernet. For laptops without ports, you’ll need:
- Ethernet adapter – A USB-to-Ethernet adapter allows connecting laptops, tablets, or smartphones via Ethernet.
2. Identify the Ports on Your Router
Look at the back of your wireless router. You should see:
- WAN port – Connects the router to your internet source (commonly labeled "Internet").
- LAN ports – Local Area Network ports. Connect your devices to these ports.
- Other ports – May include USB, phone, or coaxial ports depending on model. Ignore these for now.

3. Connect the Ethernet Cable to the Router
Take your Ethernet cable and plug one end into an empty LAN port on the router. Ensure the cable clicks or locks into place.
If all LAN ports are occupied, you can add an Ethernet switch.

4. Connect the Other End to Your Device
Plug the second end of the Ethernet cable into the Ethernet port on your device (computer, smart TV, etc). Ensure the cable is fully inserted and locked in.
For laptops or mobile devices without Ethernet ports, use your USB-to-Ethernet adapter instead.
5. Configure Your Device
Most devices will automatically detect the Ethernet connection. If not, manually select the wired connection:
Windows:
- Go to Network Connections settings
- Click the Ethernet network
- Choose "Connect"
Mac:
- Go to Network preferences
- Select Ethernet from the left sidebar
- Click "Apply"
Linux:
- Open the network manager
- Click the Ethernet connection
- Select "Connect"
Refer to your operating system’s documentation for exact steps.
That’s it! Your device is now communicating with your wireless router via Ethernet.
Troubleshooting Tips
If you don’t see a connection:
- Try unplugging and reconnecting the cable at both ends.
- Verify cable integrity—no damaged or bent pins.
- Check if the cable is Cat5e/Cat6. Lower-rated cables won’t work.
- On your device, disable WiFi to force Ethernet detection.
- Update your device’s network drivers.
Still not working? An Ethernet switch can help split connections between multiple devices.
Maximizing Ethernet Connections
Ethernet Switch
If you need more Ethernet ports than your router provides, an Ethernet switch expands your LAN ports. Connect the switch to your router via Ethernet, then plug devices into the extra ports.

Wired Backhaul
For mesh WiFi systems, connecting Ethernet between the router and secondary access points optimizes performance by replacing wireless backhaul with a wired connection.
Hybrid Wired/Wireless Setup
- Use Ethernet for high-performance devices (gaming PCs, streaming TVs, workstations).
- Reserve WiFi for mobile devices (phones, tablets).
This prevents congestion and maximizes bandwidth for each connection type.
Frequently Asked Questions
Q: Can I use Ethernet and WiFi at the same time?
A: Yes! Ethernet connections don’t disable WiFi. Devices can use either connection simultaneously.
Q: Is Cat5e Ethernet cable ok?
A: Cat5e supports gigabit speeds and is sufficient for most homes. Cat6 allows longer runs and future-proofing. Avoid anything below Cat5e.
Q: Do I need special Ethernet cables?
A: Standard Cat5e or Cat6 cables work in nearly all cases. No crossover cables or special wiring needed.
Q: What’s the maximum Ethernet cable length?
A: Cat5e allows up to 100 meters; Cat6 supports up to 250 meters (longer runs may require special conditions).
Q: My devices don’t have Ethernet ports. What now?
A: Use USB-to-Ethernet adapters to add wired connectivity to laptops, tablets, or smart TVs.
Tips for Optimizing Ethernet Performance
- Keep cable runs as short as possible.
- Avoid tightly bundling cables to prevent interference.
- Test multiple cables if speeds are slow (faulty cables are common).
- Disable WiFi on wired devices to prevent conflicts.
- Inspect cables/ports periodically for damage.
- Update network drivers and router firmware.
- Use an Ethernet switch for additional wired connections.
Final Thoughts
While WiFi is convenient, Ethernet delivers unmatched speed, stability, and low latency for gaming, streaming, and work.
Setting up Ethernet is quick and easy—just follow the steps above. Use wired connections for critical devices and WiFi for others to optimize performance.
