Hotspot Ubuntu 11.10

[mokup]

Salve ragazzi,
volevo configurare una rete wireless hotspot su ubuntu 11.10, per farlo ho seguito questa guida:

http://www.lffl.org/2011/12/ubuntu-realizzare-un-hotspot-wifi-per.html

Dopo aver fatto questi passaggi però non vedo nessuna rete.

Vi mando la configurazione:

SSID: nome rete
Modo: Ad-hoc
Banda: automatico
Indirizzo Mac dispositivo: è quello dell'interfaccia eth1

Poi per quanto riguarda Impostazioni ipv4:
Metodo: Condiviso con altri computer

Ho provato sia impostando una password wep, sia senza ma il problema rimane...

Qualcuno sa consigliarmi qualcosa?

Grazie, ciao

Indirizzo Mac dispositivo: è quello dell'interfaccia eth1

eth1? Non volevi realizzare un hotspot wifi? Quante schede di rete hai? La scheda wifi è la eth1? Non è che ti sei confuso con la wlan0?

Puoi postare i risultati dei seguenti comandi?

lshw -C network

ifconfig

iwconfig

sudo iwlist scan

lspci

lsmod

La wifi risulta collegata ad alice... Ho letto male? Vorresti collegarti con la wifi ad Alice e con la stessa creare l'hotspot?
Non si può creare un hotspot se la scheda wifi viene usata per la connessione ad internet. Potresti per esempio collegarti a Alice con il cavo e poi creare l'hotspot con la wifi libera.
