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 :
