I sintomi sono: connessione wifi instabile, che può funzionare benissimo o scomparire all'improvviso, oppure trasferimento dei dati interrotto anche se sembra esserci segnale. Di solito per ripristinare la connessione basta spegnere e riaccendere il wifi (sull'Aspire 1640 c'è un comodo tasto).
La scheda wifi è la Intel 2200 BG (Calexico 2) e i driver ipw2200 sembrerebbero correttamente installati.
Ecco i risultati dei vari comandi di diagnostica:
