sempre la solita macchina debian stable
un'altra scheda pci wifi
la scheda è una sola

domanda stupidissima... ma a parte ath0 che è la scheda wifi, lo che è 
la schda rete virtuale e eth0 che è la scheda rete... wifi0 e sit0... da 
dove cappero se le tira fuori?

p.s.: ho controllato più volte ma sulla piastra madre c'e' solo l'ultima 
scheda pci wifi e non c'e' null'altro attaccato, ho persino riavviato la 
macchina per essere sicuro che non prendesse qualche cappero di 
"reminescenza" da vecchie installazioni
