Por seguir intentando cosas, he probado a instalar otro firmware, en este caso el r36114 que viene al inicio del hilo.
Al parecer ahora si me reconoce el chip wifi interno. Ahora toca probar si reconoce la tarjeta usb y ajustar la configuración para ponerlo como cliente.
Este es el registro con el firmware actual:
