LED Panel Control Explained - Vigor Routers

Show all


The LEDs (lights) on the DrayTek Vigor routers can give a very quick indication of the current state of the router. This article depicts what each LED means and what actions from the users are needed. There are two sections: Business Routers and SOHO Routers.

DrayTek Business Routers

The DrayTek Business Routers are characterized by the front LED panel that groups 9 LEDs together. The routers that are part of this group include the Vigor 2865, 2866, Vigor 2927 series. Below, there is Vigor 2865ax in normal operational mode (its ACT light is blinking).
