Ciao a tutti..
Hai ragione Dario..I'm sorry..
Avevo provato ad installare la scheda compilando a mano i dirver perchè
la procedura tramite apt non aveva dato nessun risultato..
Sono passato al kernel 2.6.24 installando debian-sid...tuttavia ancora
la scheda wireless non funziona correttamente...
Adesso la scheda viene caricata regolarmente all'avvio..infatti ottengo
queste informazioni da dmesg
debian:/home/lore# dmesg | grep iwl

Appena acceso il pc digitando iwconfig/ifconfig ottengo:

Per provare a connetermi ho utilizzato sia programmi come wifi-radar,
wicd, network manager (in questo caso il programma prova ad ottenere
l'indirizzo di rete ma non riesco ad acquisirlo, cioè lavorano per un
pò ma non danno risultati) e da riga di comando con "iwconfig wlan0
essid xxxxx channel xxxx mode managed key open s:xxxx"
Secondo me il problema è quel "link is not ready" che ottengo da dmesg;
infatti le volte che mi connettevo ottenevo da dmesg "link becames
ready"..
Ho provato a mettermi accanto all'AP per risolvere il problema della
potenza del segnale... ma niente...non riesco ad associarmi...con win
dalle stesse posizioni vedo perfettamente l'AP..
Grazie per l'aiuto.
Ciao
Lorenzo
