Troubleshooting Connection Issues with TP Link Access Point

During a support session, Shane from LED Sign City assisted Tony in diagnosing a communication issue between a TP Link access point and an LED sign. The antennas connected to the sign were not displaying any lights, suggesting a power or connection problem. Before proceeding with troubleshooting, it was essential to confirm whether the sign used an internal or external controller and verify the setup of the antennas and PoE adapters.

Checklist: Before You Begin Troubleshooting

1. Verify the Customer’s Setup:

   • Confirm whether the sign uses an internal or external controller.
   • Ask about the location and setup of the TP Link antennas and how they are connected.

2. Antenna Power Check:

   • Inspect whether the TP Link antennas are powered (lights should be visible).
   • If no lights are visible, proceed to check the PoE adapter for power.

3. PoE Adapter and Cable Connections:

   • Ensure the PoE adapter is plugged in and supplying power to the antenna.
   • Check the Ethernet cables between the PoE adapter and the antenna.

4. Tools:

   • Access to the PoE adapter and its cables.
   • Ladders or equipment to reach antennas placed high up.

Troubleshooting Steps: Connection Issue with TP Link Access Point

1. Check Antenna Lights:

   • Inspect the TP Link antennas for lights. If no lights are visible, the antenna may not be receiving power.

2. Inspect PoE Adapter:

   • Verify that the PoE adapter has a white or green light, indicating power is being supplied to the antenna.

3. Check Cable Connections:

   • Ensure that all Ethernet cables are securely connected between the PoE adapter and the antennas.
   • If possible, unplug and reconnect the cables to ensure a proper connection.

4. Test Antenna Functionality:

   • Swap the problematic antenna with a working one to test if the issue is with the antenna itself or the PoE adapter.
   • If the replacement antenna works, the original antenna is faulty and needs to be replaced.

5. Replace Antenna if Necessary:

   • If the original antenna is faulty, request a replacement and test the new antenna once installed.
