problema scheda wireless "spenta"

[fedrooo]

PREMESSA


da comando

iwconfig

mi appare questo

lo              no wireless extensions.
eth0          no wireless extensions.
wmaster0    no wireless extensions.
wlan0          IEEE802.11bg ESSID:"My_Adhox_Network"
                 Mode:Ad-Hoc  Frequency:2.412 GHz  Cell:42:44:63:FC:8B:D3
                 Tx-Power=27 dBm
                 Retry min limit :7    RTS thr:off     Fragment thr=2352  B
                 Encription key:off
                 Power Management :off
                 Link Quality:0    Signal level:0   Noise level:0

                 Tx excessive retries:0  Invalid misc:0  Missed beacon:0

ora come avrete capito gia' in molti sono un niubbo xD, credo che sia spenta la scheda no? come fare ad "accenderla"?

quando penso di aver capito, il comando corretto sarebbe

iwconfig wlan0 power on

ma la risposta e' questa

 Error for wireless request "Set Power Management" (8B2C) :
     Set failed on device wlan0 ; Invalid argument.

e' normale?? come ovviare al problema?

ARRIVANDO AL PUNTO DEL PROBLEMA

tutto e' nato inserendo il comando "dhclient wlan0", questo e' cosa mi appare

invece con "dhclient eth0" accade questo

ciao fedro comunque se non sbaglio la tua penna viene riconosciuta, infatti wlan0

con eth0 non succede nulla perchè si tratta dell'interfaccia di rete ethernet che non perso abbia a che fare con quella wireless.

dai un ifconfig e vedi che ti dice.

ti suggerisco di specificare anche che disto usi(suppongo bt4).

poi lascia stare il dhcpclient e prova a usare wicd per la connessione wifi.
