[Résolu] Freeze wifi aléatoires Xubuntu 11.10 - Hercules HWNUm-300

Depuis la maj du Kernel en 3.0.0-18 et passage au firmware Free 1.1.5, je subis des freeze aléatoires (parfois toutes les minutes) de mon wifi.
J'ai fait tout ce que j'ai pu (procédure "Chibbata" pour suspendre le n - canal le moins encombré de mon voisinage (1) - nidswrapper et driver windows - réinstall de Firefox sur lequel les freeze sont les plus fréquents) rien à faire..
Ici mon résumé :

Merci d'avance pour votre temps !! smile

PS, en relisant d'autres posts, j'ajoute que l'utilitaire de connexion réseau m'indique tout aussi aléatoirement des coupures/redémarrage de la connexion, ou... rien du tout, le signal restant indiqué comme bon ou excellent)

..en revérifiant mon post j'en ai profité pour passer ma box en WPA2 AES - j'ai aussi un HP dv 6000 avec la même config ...qui n'a pas de souçis de freeze ! me demande si mon dongle n'est pas cuit... Si vous n'avez pas de soluce logicielle, auriez vous un conseil pour un dongle qui ne pose pas de problèmes ?

Re : [Résolu] Freeze wifi aléatoires Xubuntu 11.10 - Hercules HWNUm-300

salut
la manip pour suspendre le wifi N ne fonctionne qu'avec les puces wifi intel,si tu as crée un fichier iwlagn.conf dans /etc/modprobe.d/,il faut l'effacer
met a jours les modules wifi

sudo apt-get update
sudo apt-get install linux-backports-modules-cw-3.3-3.0.0-18-generic

redemarres le pc

Re : [Résolu] Freeze wifi aléatoires Xubuntu 11.10 - Hercules HWNUm-300

Merci ! Fait.
(Honte de mes bidouillages.. hmm)

J'ai eu un freeze au bout de 2mn (mais il est remonté tout seul).
..Ainsi que des irrégularités de bande passante semble t'il (parfois ultra rapide-parfois étonnamment lent)

(Après test plus avancé, je confirme : toujours des freeze, par contre plus stable qu'avant)

Dois je faire autre chose, mon dongle est il pourri ? smile

Re : [Résolu] Freeze wifi aléatoires Xubuntu 11.10 - Hercules HWNUm-300

Bon... ça continuait à foirer.
J'ai été acheter une TP-Link TL-WN721N pour 9 € , viré mon pilote Windows puis Nisdwrapper, redémarré, reconnu en natif, plus de freeze.
Petite manip à ne pas oublier : modification des connections - sans fil - sélectionner sa connexion - modifier - changer l'adresse MAC (apparait automatiquement)
(Vendrai ma Hercules sur le net 15€ à un windozien..)

Merci quand même chibbata pour ton temps, j'espère que je ne reviendrai pas t'ennuyer avec ma TP-Link ! big_smile


20/9/2012 - Retour d'expérience de 5 mois : plus jamais eu aucun problème, débit en wifi n impec.

11/9/2013 - Retour d'expérience au bout de 18 mois, passage par 12.04 - 12.10 -13.04 -13.10 : plus jamais aucuns problèmes, la TP-Link TL-WN721N fonctionne parfaitement et capte très bien à distance.

19/4/2014 - Confirme le retour d'expérience
