Titolo: Problema di autenticazione WLAN

Non riesco a collegarmi alla mia WLAN.
La rete è questa:

                        Authentication Suites (1) : PSK
Questi dati li ho presi con iwlist.
In genere io uso wpa_supplicant per collegarmi alle vare WLAN.
La configurazione che ho scritto è la seguente:
network={
    ssid="InfostradaWifi-014576"
    scan_ssid=1
    proto=WPA2
    key_mgmt=WPA-PSK
    psk="**************"
    pairwise=CCMP TKIP
    group=CCMP TKIP
    priority=5
}
I parametri sono analoghi a quelli che uso in altre reti, eppure qui
non funzionano.
Suggermenti?
Grazie in anticipo.

 Suggermenti?
lanciare wpa_supplicant con l'opzione -d o -dd
tipo:wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -d
e leggere dov'e' l'inghippo
perche non usi  wpa_passphrase ?
usage: wpa_passphrase <ssid> [passphrase]
PS se lanci wpa_supplicant senza argomenti ti spiega parecchie cosine...
-- 
last-kernel-inside

 usage: wpa_passphrase <ssid> [passphrase]
Ho provato ad usare wpa_cli ma non mi ha dato output utili.
wpa_passphrase non lo conosco. Ora guardo.
Grazie.

Ho usato wpa_passphrase ma non capisco che dovrebbe fare.
Invece ho lanciato wpa_supplicant per fare il debug. e ho ottenuto
questo:
Boh, sembra che non riconosca l'ESSID dell'AP, lo salta insieme agli
altri.

Hai riavviato il router? mi capita a volte che la cosa si risolva,inoltre 
vedi con iwlist quanti router si trovano e su quale canale,se per esempio 
siete in 3 sul canale 6 e' probabile che questo crei problemi,quindi ti 
consiglio di impostare un canale diverso,tu sai che diversi elettrodomestici 
creano interferenze? in primis i maledetti ripetitori audio/video wireless
(in particolare quelli del tuo vicino),poi forni microonde,ed altro,hai 
provato da windows con lo stesso PC? (per escludere problemi di 
configurazione).
Hai installato wicd? te lo consiglio,mi ha risolto spesso problemi di 
configurazione,questo e' quello che uso:
ap_scan=1
ctrl_interface=/var/run/wpa_supplicant
network={
       ssid="MIO_ESSID"
       scan_ssid=0
       proto=WPA RSN
       key_mgmt=WPA-PSK
       pairwise=CCMP TKIP
       group=CCMP TKIP
       psk=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
}
generato da wicd.

E` evidente il mismatch fra l'SSID impostato sul router e quello sul 
cliente.
Cliente	-> InfostradaWifi-014576
AP 	-> InfostradaWiFi-014576
