If your TP Link Deco flashing red, it usually means the Deco unit has lost its internet connection or is experiencing a setup problem. This problem can usually be fixed with a few easy debugging techniques, thank God.

What Causes Your TP Link Deco to Flash Red?

On a TP-Link Deco device, a red flashing light usually points to:

• Internet access failure

• Ethernet wire that is loose or broken

• ISP service loss

• Inaccurate network settings

• Firmware-related problems

Steps to Fix TP Link Deco Flashing Red

1. Look for Your Internet Connection

Make sure your modem is connected and getting internet service. Directly link a machine to the modem to confirm internet access.

2. Check Ethernet Cables

Double-check that all connections between the modem and the primary Deco unit are firm. If need be, replace broken wires.

3. Start Your Network Device Restorally

Turn off the modem and Deco devices. Wait thirty seconds before turning on the modem first and letting it completely connect before turning on the Deco.

4. Upgrade Deco Firmware

Open the Deco app and look for any firmware updates that are free. The most recent firmware will help to boost performance and help to fix connection issues.

5. Do a TP Link Deco reset.

Should the problem still exist, try a reset of your TP Link Deco:

• Find the Reset button on the Deco unit.

• Press and hold it for around ten seconds until the LED turns.

• Let the button go and let the device restart.

• Re-setup the Deco using the Deco app.

6. Get in touch with your ISP

Should your internet connection be lost, the Deco can keep showing a red light until it is recovered.

Finally

Usually, a flashing red light on a TP Link Deco means there's a problem with the configuration or internet access. Checking wires, restarting gadgets, upgrading firmware, or doing a TP Link Deco reset may help your network to be restored fast. Call your internet company or TP-Link support for more help if the problem still exists.
