Commençons par un petit background du sujet : Je possède une carte réseau rtl8191 (utilisant donc rtl8192se-firmware et le driver rtl8192se) En France, j'utilisais wicd comme gestionnaire de réseau et ce sans souci. Depuis que j'ai migré aux USA, je peux me connecter mais à tout moment le réseau wifi plante sans raison (impossible de naviguer mais toujours connecté). Si je tente de me déconnecter puis de me reconnecter ce n'est pas possible, il faut que je redémarre le PC.
En relisant le wiki j'ai vu que wicd pouvait être instable avec ma carte wifi, j'ai donc essayé networkmanager mais toujours avec les mêmes déboires.
Voici le résultat de iwconfig lors d'un plantage :

Pour finir je dirai qu'il n'y a aucun souci avec le PC de ma copine sous Opensuse, ce n'est donc pas lié au réseau.
Allez je poste avant un plantage...
