Common Issues and Fixes

Knowing what the lights signify can help diagnose issues. Here are some common problems and their solutions:

  1. Power Light Off:
    • Check the Power Supply: Ensure the router’s power adapter is securely plugged into the router and a working power outlet. Try a different outlet to rule out the issue with the power source.
  2. Internet Light Off or Blinking:
    • Check the Connection: Verify that the cable connecting your router to the modem is securely plugged in at both ends.
    • Restart Your Modem and Router. Unplug both devices, wait a minute, and then plug them back in. Start with the modem, wait for it to boot up, and turn the router on.
    • Contact Your ISP: If the above steps don’t resolve the issue, there might be a problem with your internet service. Contact your ISP for assistance.
  3. LAN Light Off:
    • Check the Ethernet Cable: Ensure the Ethernet cable connecting your device to the router is securely plugged in at both ends. Try using a different cable to rule out a faulty Ethernet cable.
    • Check the Device’s Network Settings: Ensure the device is set to obtain an IP address automatically.
  4. Wi-Fi Light Off:
    • Enable Wi-Fi: Use the router’s web interface or the TP-Link Tether app to ensure Wi-Fi is enabled. Sometimes, Wi-Fi can be accidentally disabled through these interfaces.
    • Check for Physical Wi-Fi Button: Some models have a physical button that enables or disables Wi-Fi. Make sure it hasn’t been pressed accidentally.
  5. WPS Light Blinking Indefinitely:
    • Cancel WPS Process: If the WPS process is stuck, press the WPS button again to cancel the pairing process. Use the traditional Wi-Fi setup method by manually selecting the network and entering the password.

  • Regularly Update Firmware: Manufacturers release firmware updates that can improve performance and security. Check the TP-Link website for updates.
  • Position Your Router Properly: Keep your router in a central location, away from metal objects and appliances that emit electromagnetic waves.
