18 March 2026

When it comes to getting online with our Android phones, we usually reach for Wi-Fi or mobile data. But did you know your Android smartphone supports a wired Ethernet connection?

Surprising, isn't it?

Now, you’re probably wondering: "How am I supposed to plug a bulky LAN (Local Area Network) cable into a phone that doesn't even have an RJ45 port?" Don't worry—it is not only technically possible, it’s actually quite simple.

In this guide, I’m going to show you exactly how to bridge that gap. Stick around until the end, and you’ll be a pro at bringing rock-solid, wired internet to your Android device.

Requirements to Get Internet On Android Via Wired Ethernet Connection

You will need the following hardware to use the wired internet connection via ethernet cable on your Android phone.

• An Android phone with a USB-C port. Not all Android phones may support this.
• A RJ45 ethernet to USB converter OTG adapter. You can choose reliable brands such as TPLink or Anker.
• A RJ45 LAN cable made of pure copper. Avoid cheap CCA (Copper Clad Aluminium) LAN cable.
• Wired internet connection in your home with a dedicated Wi-Fi router installed.

How to Connect Wired Ethernet to Android Phone (Tested Step-by-Step Guide)

Here's a step-by-step and plug and play guide for connecting wired internet connection to your Android phone via Ethernet cable. The following guide has been tested on a Samsung Android phone running One UI 8.0 and Android 16.

1. Plug in the USB-C end of the ethernet to USB-C adapter to your phone.

2. Make sure your Wi-Fi router is switched on.
3. Check the back panel of your Wi-Fi router. You'll see multiple RJ45/LAN ports there. Connect the LAN cable to any of the RJ45 port in yellow.
4. Now connect the other end of the LAN cable to the LAN to USB-C adapter that you just plugged in to your Android phone.
5. Once you make the successful connection, an ethernet icon will be visible in your phone's status bar.

   

6. You don't have to change any settings to make the internet connection work on your phone. The ethernet connection works plug-and-play on most supported Android devices. However, you can check some settings if you ever need to change them in Settings > Connections > More connection settings > Ethernet.

Pros and Cons of Using Ethernet on Android

Using wired ethernet connection is not an ideal way to use internet on your phone. The USB-C type to ethernet adapter setup with an RJ45 cable is pretty bulky for a phone. However, in some situations this setup can be useful for some users, see below.

Reasons You Should Use Wired Ethernet Internet Connection On Android: Pros

You may prefer a ethernet connection on your Android phone for using internet due to the following reasons.

1. You forgot your Wi-Fi password and don't have time to reset it.
2. You want high-speed stable internet for specific tasks.
3. You don't want to use Wi-Fi on your phone for personal reasons.
4. You are in an area with weak or unstable Wi-Fi signals.
5. You need lower latency for gaming or video calls.
6. You are downloading or uploading very large files in GBs and want a reliable connection.
7. You are troubleshooting network issues and need a direct connection.

Reasons You Should Not Use Wired Ethernet Internet Connection On Android: Cons

While a wired Ethernet connection can be useful in some cases, it also comes with several drawbacks that may make it less practical for everyday use on an Android device.

1. You lose portability because your phone is physically anchored to a cable.
2. You’re forced to carry extra gear, specifically a USB-C to Ethernet LAN adapter, which is rarely convenient.
3. Compatibility is a gamble, as not every Android device actually supports an Ethernet connection.
4. Cable management is a headache, making a mess of your space for a device meant to be wireless.
5. Your movement is restricted, so you can't exactly wander around while you're online.
6. It drains your battery faster since your phone has to power the external adapter.
7. Charging becomes a struggle because the adapter occupies your only port, requiring a specialized hub to do both.
8. It’s complete overkill for basic things like scrolling social media or casual browsing compared to just using Wi-Fi.
9. Repeated plug-and-play action can weaken or damage the USB-C port on your phone.

What’s Ethernet Tethering and How Does It Work on Android?

Think of Ethernet tethering as using your phone like a plug-in modem for your computer. Instead of sending out a Wi-Fi signal, you send the internet through a physical cable. To do this, you usually need a small adapter that plugs into your phone's charging port.

Most phones share their mobile data this way, but some can even share a Wi-Fi network through the cable. It can be more stable than a Wi-Fi hotspot, especially in interference-heavy environments, because the connection is wired and less prone to signal drops.

How to Enable Ethernet Tethering On Your Android Phone

Here's how to enable Ethernet Tethering on your Android phone.

1. Connect the type-C to Ethernet adapter for mobile with your Android phone.
2. Connect one end of the RJ45 LAN cable to the adapter and then plug the other end of the cable to your computer LAN.
3. Go to Settings > Connections > Mobile Hotspot and Tethering > Ethernet tethering. Enable this option.
4. You can now use your mobile data or Wi-Fi network from your phone on your PC/laptop using the type-C to Ethernet adapter and LAN cable.

Troubleshooting Tips For Ethernet Connection Not Working On Android

At any time you may face issues when Ethernet connection may not work as usual with your Android phone. I have listed some scenarios that will help you troubleshoot the connection issues.

1. No Ethernet Icon On Android

If you're unable to see the ethernet icon besides connecting the type-C to Ethernet adapter, then the adapter could itself be faulty. Check whether the adapter works with a modern PC.

Nearly all type-C to Ethernet adapters have a tiny LED light that keeps blinking when they're operational. So, before putting the blame totally on your adapter, just test it with several devices and also check the android ethernet adapter setup.

2. No Internet via Ethernet? Check Your DHCP Pool

If your phone won't connect through an Ethernet cable while other devices work fine, your router might simply be out of "IP addresses" to hand out.

➡ How DHCP Works

Think of DHCP (Dynamic Host Configuration Protocol) as a host at a restaurant. It assigns your phone an IP address (a table) so it can talk to the web. Most routers use a specific range, such as 192.168.1.2 to 192.168.1.100.

• The Problem: If that range is too small (e.g., only 9 slots) and you have a 10th device, your phone is "denied entry" and stays offline.
• The Fix: You need to expand the DHCP Pool in your router's admin settings.

➡ Quick Steps to Fix DHCP Issues

1. Login to your router (usually by typing 192.168.1.1 or 192.168.0.1 in your browser).
2. Navigate to LAN or DHCP Management settings.
3. Increase the Ending IP depending on the number of devices you wish to allow connection.
4. Save & Reconnect: Unplug the Ethernet cable and plug it back in.

Pro Tip: Ensure your phone's Ethernet setting is set to "Automatic" or "DHCP". If it's set to "Static," it won't even ask the router for an address. Also, If two devices are manually set to the same Static IP, the Ethernet connection will fail. So, keep a check on this.
