However, when the TP-Link Deco light is yellow, you must know that Deco is resetting. But, what does it mean when the Deco is blinking blue? Let’s help you understand that.

When the TP-Link Deco is blinking blue, it means that the Deco is ready for the installation. Thus you should install it as soon as possible.
