When your TP-Link Deco blinking red light, it indicates that it is no longer connected to the internet or, in mesh configurations, to the main Deco unit. This is the most alarming LED warning, and it usually occurs as a result of bad wires, interference, or insufficient signals.
A blinking red LED indicates that your Deco, if it’s a satellite unit, is unable to connect to the main unit. It can indicate a broken connection with the modem or ISP for a primary Deco.
How to solve a red Deco that blinks:
- Verify the connections. Verify that the Ethernet wire from your modem is connected to the appropriate Deco port.
- Restart the gadgets. Turn off and on all of your Deco units and your modem.
- Approach. To guarantee signal strength, position satellite units closer to the main Deco.
- Examine the modem. Make sure you can access the internet with your modem. By simply connecting another device, you may verify.
- As a last resort, reset. To restart, press the reset button for a brief moment (about one second). A factory reset (10 seconds hold) might be required if that doesn’t work.
In order to rebuild your network:
- Open the Deco App, then sign in.
- Verify the state of the network.
- Reconfigure or add the impacted Deco unit.
- Access with Browser: Open your browser and navigate to tplinkdeco.net if you are a Deco network member. This enables you to verify firmware, restart units, and examine device status.
- Deco devices should not be placed next to microwaves, metal appliances, or thick walls since they could weaken the signal.
