Overview of TP-Link Router Lights
Most TP-Link routers have a similar set of LED indicators, each with its own specific function. Here’s a rundown of the lights you’ll typically find on your device:
- Power LED: Indicates whether the router is powered on and functioning properly.
- Internet/WAN LED: Shows the status of your internet connection through the Wide Area Network (WAN) port.
- Ethernet/LAN LEDs: Represent the status of wired connections to your router via the Local Area Network (LAN) ports.
- WiFi LEDs: Display the status of your wireless network, often separated into 2.4GHz and 5GHz bands.
- WPS LED: Indicates the status of the WiFi Protected Setup (WPS) feature, which allows for easy wireless device pairing.
- USB LED (if applicable): Shows the status of any connected USB devices, such as external hard drives or printers.
LED Colors and Their Meanings
Now that you know what each light represents, let’s talk about what the different colors and patterns signify:
- Solid green: This is the color you want to see! A solid green light usually means the associated function is working normally.
- Flashing/blinking green: Typically indicates network activity or traffic on that particular LED. No need to worry; this is a good sign!
- Yellow/orange: A yellow or orange light on the TP-link router often suggests a warning or error, such as a weak signal or authentication issue.
- Red: Uh-oh, red alert! This color generally points to a serious problem or malfunction, like a failed connection or hardware issue.
- No lights: If an LED is completely off, it usually means that particular function is disabled, or there’s a power or connection problem.
Model-Specific TP-Link Router Light Behaviors
While most TP-Link routers follow similar light patterns, there can be slight variations between models. Here are a few noteworthy differences:
- TP-Link Archer Series (A, C, AX models): Some Archer models have separate lights for the 2.4GHz and 5GHz bands, while others use a single light to represent both.
- TP-Link Deco Mesh System Lights: Deco mesh routers often use a single, multi-color light to indicate the system’s status. Refer to your Deco’s manual for specific color meanings.
- Differences between Wi-Fi 5 and Wi-Fi 6 TP-Link Router Lights: Wi-Fi 6 (802.11ax) routers may have additional lights or indicators related to advanced features like OFDMA or MU-MIMO.
- Older TP-Link Router Light Meanings: If you have an older TP-Link router model, the light meanings may differ slightly. Always consult your specific router’s manual or support resources for accurate information.
Troubleshooting Common Issues
Armed with your new knowledge of TP-Link router lights, you’re ready to start troubleshooting any issues that may pop up. Here are some common problems and how to identify them:
- Internet down: If your Internet/WAN LED is solid red or off, your router may have lost its connection to your modem or ISP. Double-check all cables and reboot your modem and router.
- No WiFi: When your WiFi LEDs are off, your wireless network is likely disabled. Log into your router’s settings and ensure the WiFi function is turned on.
- Ethernet not working: If one of your Ethernet/LAN LEDs is off or red when a device is plugged in, there may be a problem with the cable or the connected device. Try a different cable or port to isolate the issue.
- Connection drops: Lights that flash erratically or turn red intermittently could point to an unstable connection. This may be due to interference, distance, or outdated firmware. Consider repositioning your router or updating its settings.
- Overheating: In rare cases, all LEDs may flash together, indicating your router is overheating. Ensure it has proper ventilation and isn’t located near heat sources.
Using Lights for Setup and Configuration
Your TP-Link router’s lights aren’t just for troubleshooting; they can also guide you through the initial setup process and help you confirm configuration changes. Here’s how:
- During setup, the LEDs will flash in a specific pattern to indicate the router is ready for configuration. Consult your manual for model-specific instructions.
- If you’re using WPS to connect devices, the WPS LED will flash to show pairing mode is active, then turn solid once a connection is established.
- After making changes to your router’s settings, certain lights may blink or change color to confirm the new configuration has been applied.
Lights Indicating Security Status
In addition to connection status, your TP-Link router’s lights can alert you to potential security issues:
- A rapidly flashing WPS LED could mean someone is trying to gain unauthorized access to your network using the WPS feature. If you didn’t initiate the pairing process, you may want to disable WPS in your router’s settings.
- Unusual activity on your Ethernet/LAN or WiFi LEDs, such as constant flickering when you’re not actively using the network, could indicate a possible breach or hack attempt. Check your router’s logs and connected devices list for any suspicious entries.

FAQ
What do I do if no lights are on at all?
If your router appears completely dark, first check that it’s properly plugged into a power outlet and the power switch (if present) is turned on. If the issue persists, you may need to contact TP-Link support for further assistance, as this could indicate a hardware failure.
Why is my internet light red?
A solid red Internet/WAN LED typically means your TP-Link router is not receiving a valid IP address from your modem or ISP. This could be due to a connection issue between the router and modem, a problem with your modem’s configuration, or an outage on your ISP’s end. Try rebooting both your modem and router, and if the problem persists, contact your ISP for help.
How can I troubleshoot flashing lights?
The meaning of flashing lights will depend on the specific LED and the color/pattern of the flashing. In general, flashing green is normal and indicates network activity, while flashing yellow/orange or red suggests a problem. Consult the troubleshooting section of this guide or your router’s manual for specific guidance based on which light is flashing.
The Wi-Fi Protected Setup (WPS) button on your TP-Link router allows you to easily connect WPS-compatible devices to your wireless network without entering a password. When you press the button, the router enters pairing mode, indicated by a flashing WPS LED. You can then activate WPS on your device to establish a secure connection. Keep in mind that WPS can be vulnerable to security risks, so it’s often recommended to disable it when not in use.
