5. Modos de operação

The DBIT AC1200 router supports multiple operating modes to adapt to different network setups.

5.1 Modo Roteador

In Router Mode, the device acts as the primary internet gateway, connecting to your modem and distributing internet access to all connected wired and wireless devices. This is the default mode for most home networks.

5.2 Modo Repetidor

Repeater Mode extends the coverage of an existing wireless network. The router connects wirelessly to your main router and re-broadcasts the signal, eliminating Wi-Fi dead zones.
