How to Fix the Tplink Deco Blinking Red?

It can be annoying to see your Deco blinking red, particularly if your Wi-Fi abruptly cuts off. Fortunately, this signal is your Deco's method of alerting you to issues and things that require care.

On a Deco unit, a red LED that blinks typically indicates one of three things:

• Neither the internet nor the main unit are connected to the Deco unit.
• Operation is being hindered by a firmware or hardware malfunction.
• The device is stuck in the initialization phase.

First, examine your primary Deco unit, which is the one that is attached to your modem. 

• Verify that the modem is operational, the Ethernet cable is secure, and the internet signal is strong. 
• Proceed to any satellite units displaying the red signal if the main unit is operating without any issues.
• Consider power-cycling the device by unplugging it for 30 seconds and then plugging it back in. 
• Check the network status and launch the Deco app if the red light continues. 
• The problem can occasionally be fixed by manually re-adding the unit or reassigning its location in the mesh.
• Rarely, a red blinking light might indicate that a reset or firmware upgrade is required. 
• To see whether updates are still pending, use the tplink deco login address or the browser to access the tplinkdeco.net login URL. 
• Consider doing a factory reset on the impacted device if nothing resolves the issue.
• Additionally, make sure there aren't any physical or signal barriers. Electronic interference, thick walls, or a large distance between devices can all cause connection problems.
• Although it's frustrating, a blinking red light can typically be fixed with a little troubleshooting. 
• Your greatest diagnostic tool is the Deco app, which provides information about the issue and how to fix it.
