Mi sembra ci sia qualcosa che non vada
:-o

#63

pronti. via…
1 - controlla che nel file:

gedit /etc/wpa_supplicant.conf

ci siano le righe:
network={
ssid=“SMC”
psk=“password”( in chiaro)
key_mgmt=WPA-PSK
proto=WPA
pairwise=CCMP TKIP
}

2 - dammi l’output di:

lsmod |grep ipw

ifconfig

iwconfig

#64

virus il mio file wpa_supplicant.conf sta nella cartella /etc/wpa_supplicant
ed è questo:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

1 - il percorso completo è : /etc/wpa_supplicant/wpa_supplicant.conf esatto?
2 - elimina queste due righe (almeno per il momento) dal file in questione.
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
dammi ricevuto…

#66

Si il percorso è quello.
Eliminate le prime due righe OK
