Wireless "Connection Failure"

la scheda funziona.
il modulo funziona
l’interfaccia è configurata correttamente
la wireless è configurata bene
il router pinga l’host.
l’host non pinga il router
ci manca un dettaglio, qual è?

descrivimi meglio la tua rete dispositivi - host - interfacce e indirizzi.

Allora c’è il router globespan virata 8100 per uscire su internet.
Il router è collegato ad un hub per che serve i pc degli uffici.
A quest’hub, sempre via ethernet è collegato anche il router wi-fi che è a casa (SMC), al quale dovrei collegarmi col portatile ed al quale sono collegato ora via ethernet.

criptazione wpa o wpa2?

Virus a questa domanda non so darti risposta.
Dice wpa/wpa2 però non so quale sta utilizzando
Comunque facendo il ping sul suo indirizzo risulta irraggiungile già questo

ping -I eth1 192.168.1.50

From 192.168.1.70 icmp_seq=3 Destination Host Unreachable
From 192.168.1.70 icmp_seq=4 Destination Host Unreachable

chi è il 192.168.1.50 ?

192.168.1.50 è SMC
Dovrebbe essere WPA encapsulation AES

Almeno il pc con vista che è collegato via wifi è configurato così

qui c’è una cosa strana eth1 è 192.168.1.71 perché esce con 192.168.1.70

dai un
ping -I eth0 192.168.1.50
posta l’output
ridammi ifconfig e route

Esce con 192.168.1.70?
Ah già vero esce con l’ip di eth0

Mode non dovrebbe essere impostato su MANAGED e non su Master?

Mode non dovrebbe essere impostato su MANAGED e non su Master?[/quote]

master è l’access point
managed è la periferica host
quindi è giusto

ps. mi risponde alle richieste del post #89

Al primo ping che ho fatto prima è uscito con 192.168.1.71

prima di dare iwlist eth1 scanning e iwlist eth1 modulation

Proviamo a buttare giù eth0?

mi rispondi alle richieste del post #87 ?

:oops:
e adesso dov’è andato a finire eth1?

hai dato qualche comando di down?

No sto seguendo alla lettera quello che mi dici.

dobbiamo capire il motivo del perché ha perso la configurazione.
dai un
ps -ax
posta l’output
vediamo se c’è qualche processo concorrente alle operazioni che abbiamo fatto.

no. non mi pare che ci sia nulla che possa fare quello che è successo.

allora facciamo una cosa riconfiguriamo poi controlliamo la configurazione facciamo un ping e ricontrolliamo la configurazione se la perde il problema è quello.

dai i comandi:

service NetworkManager stop

service NetworkManagerDispatcher stop

service wpa_supplicant stop

ifconfig eth1 down

iwconfig eth1 essid “SMC”

iwconfig eth1 mode Managed

iwconfig eth1 ap 00:13:F7:53:CD:4C

ifconfig eth1 192.168.1.71 netmask 255.255.255.0 up

route add default gw 192.168.1.1 dev eth1

wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant/wpa_supplicant.conf -dd -B

ifconfig

iwconfig

ping -I eth1 192.168.1.1

ifconfig

iwconfig

posta gli output

# service NetworkManager stop
