- At the back of your Wi-Fi router, you'll see multiple RJ45/LAN ports. Connect the LAN cable to any of the RJ45 ports in yellow.
- 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.
- Once you make the successful connection, an ethernet icon will be visible in your phone's status bar.
- 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 Ethernet on Android
A wired Ethernet connection can improve stability and reduce latency on Android devices, but it is less convenient than Wi-Fi due to its hardware requirements.
Pros of Using Ethernet on Android
- Lower latency compared to Wi-Fi, useful for gaming and video calls
- More stable connection in areas with weak or congested Wi-Fi
- Consistent performance for large downloads and uploads
- Useful for diagnosing network or router-related issues
Cons of Using Ethernet on Android
- Requires a USB-C to Ethernet adapter and cable
- Reduces mobility due to physical cable connection
- Not supported on all Android devices (Android 8.0 or earlier).
- May increase battery consumption depending on adapter and usage
- Prevent simultaneous charging unless a multi-port hub is used
What is Ethernet Tethering on Android?
Ethernet tethering on Android is a feature that lets your phone share its internet connection (mobile data or Wi-Fi) through a wired Ethernet connection using a USB-C to Ethernet adapter. Instead of creating a Wi-Fi hotspot, it sends internet through a physical LAN cable to another device like a PC or laptop.
This results in a more stable and low-latency connection compared to wireless sharing methods.
How Ethernet Tethering Works on Android (Simple Explanation)
When Ethernet tethering is enabled, Android routes internet traffic from your phone through a USB-C to Ethernet adapter and outputs it via a LAN cable.
The connected device treats your phone like a wired network source, similar to a modem or router.
Ethernet Tethering vs USB Tethering (Key Difference)
These two features are often confused:
- USB tethering: Shares internet using a USB cable to one connected device
- Ethernet tethering: Shares internet through a LAN cable using a USB-C Ethernet adapter
Ethernet tethering is preferred when you need:
- Lower latency connections
- More stable packet delivery
- Compatibility with wired network setups (PCs, switches, routers)
How to Enable Ethernet Tethering on Android (Step-by-Step)
- Connect a USB-C to Ethernet adapter to your Android phone
- Plug an Ethernet (LAN) cable into the adapter
- Connect the other end to your PC or laptop
- Go to: Settings > Connections > Mobile Hotspot and Tethering > Ethernet tethering
- Turn ON Ethernet tethering
Once enabled, Android automatically routes internet through the wired connection without requiring any additional apps.
Important Notes
- Requires USB-C OTG + Ethernet adapter support
- Availability depends on device manufacturer and Android version
- Connection is automatically disabled when the cable is unplugged

Troubleshooting Ethernet Connection Not Working on Android
If Ethernet is not working on your Android phone, the issue is usually caused by the adapter, cable, router settings, or device compatibility. Use the checks below to identify and fix the problem.
1. No Ethernet Icon on Android
If the Ethernet icon does not appear after connecting the USB-C to Ethernet adapter, the system is not detecting a valid wired connection.
Check the following:
- Ensure the USB-C to Ethernet adapter is properly connected
- Try a different Ethernet cable (Cat5 or higher recommended)
- Test the adapter on a PC or another compatible device
- Check for a blinking LED indicator on the adapter (if available)
If the adapter works on other devices, the issue is likely device compatibility or a faulty USB-C port.
2. Connected but No Internet (DHCP Issue)
If the Ethernet connection is detected but there is no internet access, the issue is usually related to DHCP (IP address assignment) from the router.
Common cause
The router may not be assigning an IP address due to a full or misconfigured DHCP range, preventing the Android device from connecting properly.
How to fix DHCP issues
- Open your router settings by entering
192.168.1.1or192.168.0.1in a browser - Log in to the admin panel
- Go to LAN or DHCP settings
- Increase the IP address range or DHCP pool size
- Save settings and reconnect the Ethernet cable
Additional check (important)
- Ensure the phone’s network mode is set to DHCP (Automatic IP)
- Avoid static IP conflicts between multiple devices
- Restart the router after making DHCP changes if needed

FAQ: Ethernet on Android
Q1. Does Ethernet work on all Android phones?
No. Ethernet works on most Android phones with USB-C and OTG support (generally Android 9.0+). However, support depends on the device hardware and manufacturer implementation.
Q2. Does Ethernet work on Samsung phones specifically?
Yes. Most Samsung Galaxy devices running One UI with USB-C support can use Ethernet through a USB-C to Ethernet adapter without extra apps. The connection is automatically detected in system network settings.
Q3. Is USB-C Ethernet faster than 5GHz Wi-Fi on Android?
USB-C Ethernet is not always faster in peak speed, but it is more stable and has lower latency than 5GHz Wi-Fi. This makes it better for gaming, video calls, and large downloads in unstable Wi-Fi environments.
Q4. Can I charge my phone while using Ethernet on Android?
Not directly with a basic adapter. You need a USB-C hub with Power Delivery (PD) support to charge your phone and use Ethernet at the same time.
Q5. Is Ethernet good for gaming on Android?
Yes. Ethernet reduces latency, packet loss, and jitter compared to Wi-Fi, making it more stable for competitive online gaming.
Q6. Why is my Ethernet not working on Android?
This usually happens due to a faulty adapter, unsupported USB-C OTG, damaged LAN cable, or router DHCP configuration issues.
Q7. Do I need an app to use Ethernet on Android?
No. Ethernet works natively on Android. Once connected, the system automatically switches to wired network mode.
Q8. Can Ethernet improve mobile hotspot speed?
No. Ethernet does not boost hotspot speed. It only provides a wired internet connection directly to the phone or shared device via tethering.
Q9. Is Ethernet better than Wi-Fi for video calls on Android?
Yes. Ethernet reduces connection drops and latency spikes, making it more reliable for video calls compared to Wi-Fi.
Wrapping Up
While Wi-Fi is the king of convenience, nothing beats the raw stability and speed of a wired Ethernet connection on Android. Whether you're a competitive gamer looking for zero lag or just troubleshooting a stubborn router, this setup is a lifesaver for your digital toolkit.
