ASUS MultiAntenna Service is a background component preinstalled on select ASUS laptops that manages the system’s multiple Wi‑Fi antennas. By monitoring real‑time signal quality and coordinating with the wireless driver, it automatically selects the best antenna path to maintain a stronger connection, reduce dropouts, and optimize throughput—especially when the laptop’s orientation changes or radio interference is present. The service starts with Windows, runs quietly with minimal resource use, and underpins ASUS wireless features such as Wi‑Fi Master and SmartConnect on supported models.
Because it provides low‑level antenna control, the service has no user interface and generally shouldn’t be disabled or removed; doing so can reduce wireless stability and roaming performance. It is intended for Windows 10/11 ASUS notebooks equipped with multi‑antenna designs and works alongside vendor Wi‑Fi drivers (e.g., Intel or Realtek).
