[ubuntu-it] Interfaccia eth1 (wireless) scomparsa

[Christian]

Salve,
da ieri (senza che abbia fatto nulla di particolare) non riesco più a 
connettermi alla rete via wireless.
La connessione va senza problemi via ethernet e penso che la scheda 
wireless non abbia problemi hardware poichè gestisce bene il bluetooth.

Ecco alcuni output (spero utili) per indirizzarmi alla risoluzione del 
problema.

cosa sarebbe ctrl_interface? A quel path non trovo alcun file 
var/run/wpa_supplicant.
