Buon salve, di questi tempi non v'è tempo da perdere, quindi andiamo subito al tuorlo!

Come da titolo lavoro sotto BackBox Linux, kernel 2.6.38-15-generic-pae. Quando collego la scheda esterna "Alfa network AWUSO36H" il manager di rete grafico, mi risponde con: "rete senza fili (manufacturer realtek rtl8187 rtl8187 wireless) dispositivo non pronto". So per certo che la scheda funziona, poiché su Ubuntu 12.04 Precise, gira perfettamente.

I moduli rtl8187 sono installai perfettamente come si può osservare dal seguente output:
