TP-Link Ethernet Not Working But Wi-Fi Is (or Wi-Fi Not Working But Ethernet Is)

If your TP-Link Ethernet is not working while Wi-Fi is fine, or your Wi-Fi has stopped working while your wired connection is unaffected, the cause is usually specific to that connection type. This page covers both scenarios so you can identify your situation and skip to the relevant steps. The Ethernet troubleshooting section walks through checking the LED indicator, rebooting, testing with another device, and verifying IP settings.

Key Takeaways

• If only Wi-Fi is not working on your TP-Link router, refer to the dedicated Wi-Fi troubleshooting guide linked below for step-by-step fixes.
• If Wi-Fi is working but Ethernet is not, start by checking the Ethernet LED on the router to confirm the connection is being detected.
• Rebooting both the affected device and the TP-Link router is a recommended first step before deeper troubleshooting.
• If another device works fine on the same Ethernet cable and port, the issue is likely with the original device rather than the router.
• Devices connected via Ethernet should be set to obtain an IP address automatically. A static IP misconfiguration is a common cause of wired connection failures.

When Wi-Fi Is Not Working

If your Wi-Fi connection has stopped working but your Ethernet is fine, follow the steps in our dedicated Wi-Fi troubleshooting guide: What should I do if wireless connection cannot work on TP-Link Wi-Fi router?

When Ethernet IsNot Working: Troubleshooting Steps

If the wireless connection is working but the Ethernet connection is not working, please refer to the steps below:

Step 1: Check the Ethernet LED Indicator

Check the corresponding Ethernet light on the router. If the Ethernet light is not lit up, it’s possible that the Ethernet cable or the port is not working properly. Please try another working Ethernet cable or LAN port on the TP-Link router.

Note: For routers with only one indicator/LED, you may check whether the device itself has detected the Ethernet connection. If yes, go to the next step.

Step 2: Reboot Your Device and Router

Restart both your device and your TP-Link router. This clears temporary network issues that can cause a wired connection to stop working even when the hardware and settings appear correct.

Step 3: Test With Another Device

Connect another device to the router using the same Ethernet cable on the same port. If the Internet works on another device, the issue is likely on the original device. Please contact the device's technical support for assistance.

Step 4: Check Your IP Address Settings

Your device should be set to obtain an IP address automatically. A manually assigned static IP is a common cause of Ethernet not working, even when the physical connection looks fine. Check your settings as follows:

• Windows: Open Network Connection Details and confirm that "DHCP Enabled" is set to "Yes."
• Mac: Go to System Preferences, then Network, then Advanced, and confirm that "Configure IPv4" is set to "Using DHCP."

If either setting is incorrect, refer to How to configure wired TCP/IP Properties of my computer for step-by-step instructions.

If the steps above do not resolve the issue, contact TP-Link technical support with the following information:

• A screenshot of the IP info on the affected device.
• The brand name, model number, and operating system of your wired device.
• The model number and hardware version of your TP-Link router
