Recent updates may have expanded access to feature(s) discussed in this FAQ. Visit your product's support page, select the correct hardware version for your device and check either the Datasheet or the firmware section for the latest improvements added to your product.
Note: Refer to this FAQ if the router's other LEDs are malfunctioning in addition to the Internet LED.
What should I do if the LED of the TP-Link router is abnormal
Please first verify that the cable is detected by your router. If the internet light on your router is off or there are any error messages on the TP-Link router's web interface, such as "WAN Port unplugged" or "something wrong with the hardware connection", refer to How to distinguish the RJ45&RJ11?
If your cable is appropriate for your router, please use the following steps for troubleshooting:
Step 1: Verify that the modem is properly connected to the router's internet/WAN port. If you are experiencing issues, it is recommended to always try a new CAT5E or higher Ethernet Cable.
Step 2. Ensure that your Modem is working properly by connecting a wired device/PC to your modem and seeing if it can connect to the internet. You may also try to set up an older router to see if it can detect the WAN connection
- If other devices, like computers, can’t recognize the modem, the modem is most likely the cause of the problem. We advise you to get in touch with the modem's support staff, oftentimes this will be your ISP.
- When other devices can recognize the modem, and for the routers which have separate internet LED, please go to Step 3.
For the routers like the Archer AX3200/AX11000/AX6000/C5400 etc which have only one LED Indicator but their web interface displays the error "WAN Port unplugged" or "Something Is Wrong with the Hardware Connection", please go to Step 4.
Step 3. Disconnect the modem from the router, then attach the same Ethernet wire from the router's WAN port to one of its LAN ports, and check to see if the router's Ethernet and internet lights are on.
- If the router's internet and Ethernet lights are both OFF it is possible that:
The WAN port of the router may be faulty, or,
The Ethernet cable may have a problem
Suggestion:
Use a Different Ethernet Cable and Retest the Connections
Contact the TP-Link support team to get further assistance.
- If the router's internet and Ethernet lights are both ON, it is possible that:
Possible Reason:
The router is failing to negotiate speed with the modem correctly. Go to Step 4.
Step 4. Connect the modem back to the WAN port of the router, as you normally would, and log into the web interface of the TP-Link router. Under Advanced > Internet > “Internet Port Negotiation Speed Setting”, force the internet port negotiated speed to 100Mbps full duplex, and see whether the internet LED comes on.
