Déconnections intempestives en wifi
Bonsoir
Alors je vous expose mon problème, j'utilise pour me connecter à ma box une clef wifi MSI US54SE, celle ci est très bien reconnu, je peut me connecter à mon hotspot, mais au bout d'un moment celle ci se déconnecte et ne trouve plus aucun point ou se connecter, c'est seulement en la débranchant et rebranchant qu'il réapparaissent et que je peut me reconnecter. J'ai essayé network-manager et wicd mais le problème est toujours le même.
J'aurais ainsi besion de votre aide
Merci d'avance

Re : Déconnections intempestives en wifi
Salut
Le driver que tu utilise est apparemment intégré au noyau. Qu'as-tu comme firmware (/lib/firmware/zd1211) ?
Source: http://sourceforge.net/projects/zd1211/files/ (ça date de 2007!)
>>> ubuntu 10.04 | Openbox 3.4 | vim, terminator, vimperator <<<
Nobody was born with Linux knowledge...
