Salve a tutti.
Sul mio portatile c'e' una scheda wifi realthek rtl8187 (che con Xp si collega perfettamente).
La scheda sembra funzionare perfettamente (mi fa vedere le reti wireless disponibili - vedi allegato)
Quando accendo mi chiede di inserire la chiave "WAP e WPA2 Personal", e codi' inserisco il codice che e' riportato sul fondo del modem alice 2 plus wifi, ma non si connette !!
Ecco un po' di interrogazioni effettuate dalle quali (mi pare di capire) che il modulo wifi funzioni:
