¿Cómo configurar un adaptador inalámbrico USB de Belkin (F5D7050A)? (Linux Mint 18.1 Xfce)

Question

Recién comencé a usar Linux y he estado intentando configurar mi antiguo adaptador de red USB inalámbrico G de Belkin sin suerte. El sistema detecta el dispositivo y Network Manager muestra la opción de activar/desactivar wifi, pero no puede encontrar ninguna red ni siquiera con el 'escaneo de DISPOSITIVO iwlist' (no muestra resultados de escaneo). Ya intenté instalar los controladores rt2500usb con ndiswrapper pero aún así el mismo resultado.

Sería genial si alguien pudiera ayudarme. Gracias
