Scheda iwl3945 spenta su Amilo Li2735
Salve a tutti,
ho un problema che non riesco a risolvere in alcun modo.
Ho un portatile Fujitsu-Siemens Amilo Li2735, che monta come
scheda wireless una Intel 3945ABG.
Non riesco a far funzionare la scheda wireless, poiche' risulta
sempre spenta. Cercando in Rete ho letto che la soluzione stava
nell'installare il modulo acerhk, il quale attiva i tasti funzione,
incluso lo switch della scheda wireless (FN+F1).
In realta' tutte le prove che ho effettuato hanno dato esito negativo.
Vi allego i log di sistema ed il dettaglio delle prove effettuate.
Distribuzione: Debian Squeeze
Kernel: 2.6.30.9 (attuale)
Kernel Prec: provato anche con 2.6.26 e 2.6.30, senza esito
Firmware Scheda di Rete: 15.32.2.9
File utilizzati
/etc/modprobe.d/amilo_special_keys.conf
install acerhk /sbin/modprobe --ignore-install acerhk force_series=6805
autowlan=1; echo 1 > /proc/driver/acerhk/wirelessled
/etc/modprobe.d/iwl3945.conf
alias wlan0 iwl3945
options iwl3945 disable_hw_scan=1
/etc/rc.local
rmmod -f iwl3945
modprobe iwl3945 disable_hw_scan=1
exit 0
Prove effettuate
1. Lancio dei comandi "rmmod iwl3945" e "modprobe iwl3945
disable_hw_scan=1" e riavvio del sistema
2. Load di "iwl3945.conf" e "rc.local"
3. Load di "amilo_special_keys.conf"
4. Load di tutti e tre i file descritti sopra
Ho anche provato anche a modificare a manina il valore presente nel
file /sys/bus/pci/drivers/iwl3945/module/parameters/disable_hw_scan,
previa assegnamento del permesso di scrittura (al caricamento del modulo
i file sotto la directory parameters hanno solo permessi di lettura),
ma senza successo, il messaggio "Kill switch must be turned off for
wireless networking to work" non accenna a sparire.
Note
Per compilare correttamente il modulo acerhk (versione 0.5.35) per
il kernel 2.6.30.9 ho dovuto:
- passare i CFLAGS come EXTRA_CFLAGS nel Makefile
- modificare le chiamate della struttura "proc_dir_entry" (che si
trova nel file linux/proc_fs.h dei sorgenti) dal campo "owner" (non
piu' presente) al campo "name".
Il modulo cosi modificato viene caricato senza errori, ma funzionano
fino ad ora solo i tasti di regolazione del volume (ne' lo switch della
scheda wireless ne' la regolazione della luminosita' funzionano).
