wlan0 e Mepis

[Bugu]

Ho installato la wireless su Mepis. Sembra configurata ed attiva, questa è la risposta di ifconfig e iwconfig:

root@alex-mepis:~# ifconfig

root@alex-mepis:~# iwconfig

eth0      no wireless extensions.

wmaster0  no wireless extensions.

Ma nonostante io sia a 30 cm dall'access-point, non mi rileva alcun segnale.
Che verifiche posso fare per sapere se sta girando bene la scheda wifi?

porta su l'interfaccia wifi assegnandole un ip(ifconfig wlan0 192.168.1.7 up ), poi fai una scansione delle reti (iwlist wlan0 scan), vedi se ti trova la rete che ti interessa, e in caso affermativo, connettitici (iwconfig wlan0 essid nomerete key chiaverete se usi wep, se usi wpa, cerca su qualche wiki come configurare il file e poi lancia wpa_supplicant).

[Bugu]

ok, grazie, ora provo. Ma wpa_supplicant lo lancio solo se la wifi ha il WPA?

[Bugu]

Se do un IP a wlan0 la risposta è questa:

root@alex-mepis:~# sudo ifconfig wlan0 192.168.1.199 up
SIOCSIFFLAGS: No such file or directory
SIOCSIFFLAGS: No such file or directory

Se faccio iwlist wlan0 scan:

root@alex-mepis:~# iwlist wlan0 scan
wlan0     Interface doesn't support scanning : Network is down

[Bugu]

Se provo a uppare la wlan0:

root@alex-mepis:~# ifup wlan0
Ignoring unknown interface wlan0=wlan0.

[weseven]

probabilmente ha un alias, controlla con ifconfig -a

se hai una intel pro wireless 3945, e un kernel >= 2.6.24

dai
"iwconfig wlan0 txpower 25"
e prova a rilanciare lo script per la connessione all'access point.
tipo "/etc/init.d/net.wlan0 restart"

Fai l'operazione finchè non si collega.

Se si collega connettiti a qualcosa che tiene la connessione UP, tipo MSN o IRC..
perchè se lasci la connessione inutilizzata per tipo 1 minuto (cioè senza essere collegato a niente in maniera "persistente" si scollega.)

:\ sennò metti su un kernel 2.6.22.. e il modulo iwlwifi esterno :\

[Bugu]

Ho un kernel 2.6.22 e ho caricato iwlwifi esterno...
