A flashing red light on your TP Link Deco usually indicates a connection or network problem. It may happen because of an internet outage, a loose cable or an issue with the Deco unit. If your Deco shows red frequently and the TP Link Deco flashing red issue continues then follow the steps below.

1. Check Your Internet Connection

First, check whether your modem has internet access. Connect another device to your modem and test the connection. If other devices cannot access the internet then contact your internet service provider.

2. Restart Your Deco

Turn off your modem and all Deco units. Wait about one minute. Turn on your modem first and allow it to connect to the internet. Then turn on the Deco units. Check whether the red light disappears.

3. Check the Ethernet Cable

A loose or damaged Ethernet cable can cause connection problems. Remove the cable from your modem and Deco. Connect it again securely. If possible, use another Ethernet cable to check whether the problem is caused by the cable.

4. Check Deco Placement

Place the main Deco close to your modem. Avoid placing it inside cabinets or near devices that may cause wireless interference. Secondary Deco units should also be placed where they can maintain a stable connection with the main unit.

5. Update the Deco Firmware

Open the Deco app and check for available firmware updates. An outdated firmware version can sometimes cause connection instability. Install the recommended update and restart the Deco system after the update.

6. Check for Frequent Disconnections

If your tp link deco keeps going offline then check the modem connection and power supply. Also check whether the issue affects one Deco unit or the complete network. If only one unit disconnects frequently then move it closer to the main Deco and test again.

7. Perform a TP Link Deco Reset

If the problem continues, you can try a TP Link Deco reset. Locate the reset button on the Deco unit. Press and hold it according to the device instructions until the LED changes. Resetting removes the current configuration, so you will need to configure the Deco again using the Deco app.

Conclusion

A red flashing Deco light usually points to an internet or connection problem. Checking the modem cables' power supply placement and firmware can help restore the connection. If these steps do not resolve the issue, a TP Link Deco reset may help as a final troubleshooting step.
