Hello,
oh un problème de wifi, quelle banalité.
Network-manager voit des réseaux wifi, dont le mien. Je peux m'y connecter c'est ok une paire de minutes - mais très lent - mais dès que ça déconnecte - pourquoi ? - plus moyen d'y retourner : demande du mot de passe, ça relance la connexion, puis redemande le mot de passe, en boucle.
Routeur Bbox, en wpa2 + AES, sur le canal 4 en manuel, qui émet en b/g.
Le pc, il s'agit d'une tour avec une carte wifi tplink pci ex TL-WN881ND sous UBUNTU 14.04.5. Comportement identique sous 16.04.2.
Seul « truc » tenté pour l'instant, ajouter à /etc/modprobe.d un fichier ath9k.conf contenant options ath9k nohwcrypt=1 mais sans différence après reboot.
