If your TP Link Deco flashing red light appears, it usually means your Deco unit has lost its internet connection or is experiencing a setup problem.  Most problems can be fixed with only a few easy troubleshooting techniques; this is the good news. Use the instructions below to restore your network fast.

Common Causes of TP Link Deco Flashing Red 

• Internet connection is briefly unavailable.

• Unwound or damaged Ethernet cable.

• The modem or router connection is not right.

• Old system software needing a deco firmware change.

• Partial or wrong Decal configuration.

How to Resolve the Issue?

1. Verify your Internet connection

Make sure your modem is online and your internet service is working. Restart the modem and wait till all status lights stabilize.

2. Check Cable Connections

Check to see whether the Ethernet cable connects the modem to the primary Deco unit firmly. Should the cable look damaged, replace it.

3. Reset the Deco System

Disconnect the Deco unit for around thirty seconds then plug it back. Give the gadget a few minutes to get back in touch with the network.

4. Finish the Deco Setup

Check inside the TP-Link Deco app to be sure the setup of Deco was done properly. Should required, take the device off the app and re-add it.

5. Update Decoco Firmware

Open the Deco app and look for new updates. The newest Deco firmware upgrade installation helps to fix flaws, increase stability, and solve network problems.

6. Start the Deco unit again

If the red light stays on, push and hold the Reset button for around 10 seconds until the LED changes. Then start the setup once more.

Final Thought

A TP Link Deco flashing red light typically points to a configuration or connection problem rather than hardware malfunction. You may quickly restore your mesh Wi-Fi system by checking your internet connection, checking wires, finishing the Deco setup, and loading the most recent Deco firmware upgrade. Should the problem persist after these measures, get in touch with TP-Link support for more help.
