This document briefly summarizes the results obtained during the first technical commissioning of GIANO at the TNG, in July 2012. We describe, identify and discuss in some details the only important problem which we encountered, namely the very low overall efficiency of the system when observing the sky and astronomical targets. We also present the design of the new fore-optics and fiber-feed system which should solve this problem.
