Titolo: Installazione USB wireless - prima ok poi ko

Ieri sera ho configurato una chiavetta usb wifi in un pc vecchiotto nel 
quale avevo appena installato Ubuntu 10.04.
Compilati i driver forniti dal costruttore, il sistema l'ha vista 
subito. Stamattina riaccendo il PC ma non c'� verso:
 
Pare sia ancora l�:
 
10401$ iwconfig wlan0
wlan0     802.11b/g  Mode:Managed  Access Point: Not-Associated
           Bit Rate:0 kb/s
           Retry min limit:7   RTS thr:off   Fragment thr:off
           Power Management:off
           Link Quality=0/100  Signal level=0 dBm  Noise level=0 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:0   Missed beacon:0
 
 
 
Tento di abilitarla:
 
10401$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Risorsa temporaneamente non disponibile
 
 
Che significa ?
 
Ringrazio in anticipo per qualsiasi aiuto.

 SIOCSIFFLAGS: Risorsa temporaneamente non disponibile
 
Il driver � caricato? modprobe lo vede?

Bella domanda, allora considerate le mie scarse capacit� di dico cosa ho 
fatto:
 
Seguendo le istruzioni fornite dal produttore ho compilato con make, 
dopodich� ho eseguito il comando:
 
  insmod 8712u.ko
 
da cui posso immaginare che il nome del modulo del driver sia 8712u.ko (???)
 
401$ sudo modprobe 8712u.ko
FATAL: Module 8712u.ko not found.
 
Probabilmente non � il nome corretto.
 
HELP !


vedi se lo trovi cos�
 
modprobe -l | grep 8712u



Nulla.
 
401$ modprobe -l | grep 8712u
401$
 
Comunque il file 8712u.ko sta nella directory dove l'ho compilato.

 Comunque il file 8712u.ko sta nella directory dove l'ho compilato.
 
Prova:
 
sudo cp /ladirectorydovesta/8712u.ko /lib/modules/`uname
-r`/kernel/drivers/net/wireless
sudo depmod -a
sudo modprobe 8712u



 
 
Ok, adesso lo vede. Ma l'errore quando tento di attivare la risorsa rimane:
 
$ modprobe -l | grep 8712u
kernel/drivers/net/wireless/8712u.ko
$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Risorsa temporaneamente non disponibile
$
 
 

No so, ma secondo me non � un problema di driver, infatti con ifconfig 
-a si vede:
 
$ ifconfig -a

Secondo me non basta caricare il modulo nel kernel perch� al successivo 
riavvio sei punto a capo con il modulo non caricato, devi segnalare in 
un file specifico (non so quale sia in ubuntu) che all'avvio vuoi che 
quel modulo sia caricato e magari fare attenzione ad eventuali conflitti 
(che non sembrano esserci nel tuo caso) e quindi blacklistare i moduli 
relativi che si autocaricano quando l'id della tua chiavetta wifi � 
riconosciuto.

 file specifico (non so quale sia in ubuntu) che all'avvio vuoi che
[...]
 
Il problema è che al riavvio successivo ricarico il modulo ma mi dà un 
errore che al primo caricamento non mi dava.
 
Mi spiego meglio:
 
CON OS APPENA INSTALLATO
1) Compilo i driver:
make
 
2) Carico il modulo:
insmod 8712u.ko
 
3) Abilito interfaccia wlan
ifconfig wlan0 up
 
E tutto funziona per il meglio.
 
AL RIAVVIO SUCCESSIVO
1) Ovviamente non ricompilo
 
2) Carico il modulo
insmod 8712u.ko
 
3) Abilito interfaccia wlan
10401$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Risorsa temporaneamente non disponibile
 
mi da questo errore e non c'è verso di riattivare la wlan.
 
 


per vedere i moduli caricati devi dare lsmod (che lista /proc/modules)
risulta caricato?


 
 
va messo in /etc/modules


 mi da questo errore e non c'è verso di riattivare la wlan.
 
Provato a rimuovere il modulo e ricaricarlo?
(rmmod 8712u modprobe 8712u)
vedi se questo ti schiarisce le idee su quel (pessimo) adattatore wi-fi
http://tinyurl.com/cthgy8u
 
 
un'altra cosa,riavvia il fottuto network-manager ogni volta,meglio 
ancora,eliminalo e usa wicd
 
PS se da un secondo terminale lanci un tailf /var/log/messages puoi 
vedere in tempo reale che succede.
 
 
 


 
Se da un terminale tento di far risalire la rete con il solito messaggio 
di errore:
 
$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Risorsa temporaneamente non disponibil
 
 
Nell'altro ho:

ma a parte il doppio messaggio non vedo errori.
 
Grazie per l'aiuto.

Parrebbe di sì:
 
$ sudo lsmod

 [...]
 
potresti sfilare e rimettere la chiavetta e postare l'ultima parte di dmesg?



 
Vedo un po' di errori ma francamente non saprei cosa fare.
Grazie di nuovo per l'aiuto.



 ma a parte il doppio messaggio non vedo errori.
 
esiste rtl8192sfw.bin in /lib/firmware ?
 
find / -iname  rtl8192sfw.bin che dice ?
 

 sagra,channel:6, qos:0, myHT:1, networkHT:0, mode:2
 
prova a sostituire il firmware che abbiamo copiato con questo:
 
wget 
http://launchpadlibrarian.net/37387612/rtl8192sfw.bin.gz
 
gunzip rtl8192sfw.bin.gz
 
Pare che quello fornito con ubuntu 10.* non funzioni correttamente.



 
 
HA FUNZIONATO !!!!!!!!!!!!!!!!
 
Grazie Andrea.
 
E' la prima volta che riesco a compilare un driver per una periferica e 
farla funzionare. Avevo provato in passato per una chiavetta UMTS ma mi ero 
perso tra gli errori di compilazione, certo che anche questa non � stata 
particolarmente immediata tra directory scritte male e .bin non funzionanti.
 
Grazie 1000 di nuovo.
 
Mik.
 
 
 


 
Ho risolto, ti ringrazio. Come si vede nell'altro post l'errore (uno degli 
errori) stava proprio in questo file che con Ubuntu 10.xx ha qualche 
problema.
 
Mik.
 
 

 Grazie 1000 di nuovo.
 
Prego, è stata una soddisfazione anche per me aver risolto il tuo problema.
