Perte wifi après réinstallation (12.04)
Après une réinstallation, je perds le wifi après environ 5 min. Néanmoins Network manager m'indique toujours une connexion.
Lorsque je perds la connexion, re-cliquer sur le nom de mon wifi (via Network Manager) réactive la connexion !
Merci d'avance pour le coup-de-pouce 
Voici ce que me donne wifichek

Re : Perte wifi après réinstallation (12.04)
Salut,
Ton routeur wifi fait a la fois du wpa1 et du wpa2, ce qui est source de dysfonctionnement. . change le cryptage/chiffrement pour soit que du WPA1 TKIP, soit (et mieux) que du WPA2 AES (n'oublie pas d'enregistrer les changements et de redémarrer ton routeur wifi.
Puis re test le wifi une fois que ton routeur aura redémarré.

Re : Perte wifi après réinstallation (12.04)
Merci pour la réponse.
Désolé, je n'ai pas bien compris si tu recommandais WPA1 + TKIP ou WPA2 AES ?
J'ai néanmoins essayé les deux, mais le problème subsiste.
Ce que je ne comprends pas, c'est qu'avec mon installation précédente (aussi 12.04) et même config de routeur, je n'avais pas ce problème...

Re : Perte wifi après réinstallation (12.04)
je recommande plutot le wpa2 AES (appelé aussi WPA2 PSK)
tu as bien enregistrer les changement de cryptage et rebooter le routeur après ?
