Debian Jessie - Partager sa connexion filaire en WIFI (hotspot)

Tags: #<Tag:0x00007f63f1e95578> #<Tag:0x00007f63f1e95410>

Bonjour à tous,

Mon PC tourne sous Debian 8 Jessie, Gnome 3.14.1.

Je précise tout d’abord que ce problème a déjà été rapporté au moins deux fois sur ce forum, mais aucune solution claire n’a été proposée.

Je rencontre un problème avec l’option “Utiliser comme point d’accès…” dans les paramètres du Network Manager de Debian Jessie - sous Gnome : je ne peux choisir aucune option, et lorsque je l’allume, il s’active avant de se désactiver automatiquement quelques secondes plus tard.

Cela est d’autant plus troublant que cette procédure fonctionnait parfaitement sous Debian Wheezy, avec exactement la même configuration matérielle et réseau - à partir de Network Manager !

Voici quelques précisions sur le matériel :

Voilà, n’hésitez pas si vous avez des idées !

Merci par avance.

Lance la commande iw phy phy0 info. Dans les premières lignes, tu dois trouver quelque chose du genre :
Supported interface modes: * IBSS * managed * monitor
Par exemple, cette carte wifi ne peut que faire du ad-hoc (IBSS), se connecter à un point d’accès (managed) et capturer le trafic du réseau (monitor).
Pour faire un point d’accès avec une carte wifi, il faut que la carte wifi et le pilote associé gèrent le mode. Je ne me souvient plus comment s’appelle le mode pour le wifi.
