Why is My Deco Blinking Blue Even after Deco Setup?

The blinking blue light on the Deco signifies that the mesh system is ready for the setup process. However, when this light turns solid blue, it means that the TP Link Deco setup is going on. But, there are times when the Deco keeps flashing blue even after the setup process. If you too are complaining about your Deco blinking blue, you should read the post.

What to Do If Deco Keeps Flashing Blue after Setup?

The major reason why the Deco mesh keeps blinking blue even after the setup process is that you have not connected the main unit to the modem properly. In that case, you are suggested to refer to the following points:

• Ensure that the Ethernet cable connection between your Deco mesh main unit to the router is finger-tight.
• Be sure that the LAN port on your root router is working fine. If not, try using another port.
• The LAN cable in use must be free of cuts.

Solution 1: Ensure Stable Power Supply

You must ensure that the Deco unit is connected to a working wall socket. The power adapter of the mesh unit must be properly connected and should be the genuine one. Also, the power cord should perfectly fit the adapter and the connector on the Deco unit.

Note: In case, it is your Deco satellite unit flashing blue, it is suggested that you plug them into working wall sockets near the main unit.

Solution 2: Check with Your ISP

Chances are that the setup process is completed but the internet services are not active from the end of your Internet Service Provider. Therefore, get in touch with him and verify if everything is working fine. In case, it is not, ask him to fix things. You are also suggested to check with him if the Ethernet port of the router to which you have connected the main Deco unit is opened from his end or not. Just in case, it is not, you should ask him to activate it.

Solution 3: Restart the Deco System

You should now restart your Deco system to get rid of any technical glitches making it flashing blue even after a successful setup. To restart, pull the Deco unit’s plug out of the power outlet and wait for some time. Thereafter, reconnect the adapter to the electrical outlet and observe whether the Deco blinking blue issue has been fixed or not.

Solution 4: Re-position Satellite Decos

Satellite Decos connect wirelessly to the main Deco unit. Therefore, if the satellite Deco unit is found flashing blue, you are suggested to place it a little closer to the main unit so that the internet connection will get back and the setup process will get completed. However, you are supposed to ensure that the Deco units are not placed near devices emitting electromagnetic waves and reflexive surfaces.

Solution 5: Reset the Deco

If the Deco is still blinking blue, then you are left with the technique of resetting the mesh system. For this, check the bottom panel of the mesh unit. You will see the Reset button there. Press it carefully for 1 second. Your Deco unit will reset. You can set it up once again using the Deco app.

The Conclusion

The Deco blinking blue is actually not an issue. It just means that the system is ready for setup. However, things are supposed to be addressed if the Deco keeps flashing blue even after the installation process. With the hope that the given tips will help you complete Deco setup effortlessly and fix the blue light issue, we are wrapping up the post.
