Wifi aléatoire Natty 11.04 - D-link DWA-547 - WIRELESS N
Bonjour,
Je suis passé sous Natty amd64 il y a quelques jours et j'ai un petit souci de wifi.
Ubuntu se connecte bien au démarrage (ou quand je lui demande) mais quelques minutes (voir seconde) après la connections je perds du débit. A tel point qu'il ne m'est plus possible de naviguer et que je dois désactiver la confection et la réactiver pour pouvoir continuer. Le temps de fonctionnement est très aléatoire.
J'ai une carte D-Link DWA-547 - WIRELESS N, et les pilotes sont ceux installés par défaut avec Natty.
Je vous donne le résultat de commandes à un moment ou la connection semble fonctionner à peu près correctement :

tu peux essayé ça

Re : Wifi aléatoire Natty 11.04 - D-link DWA-547 - WIRELESS N
Bonjour,
Même problème depuis le passage à natty avec un D-Link DWA-556.
C'est bien le module ath9k qui est utilisé, cependant je n'ai pas le fichier /etc/modprobe.d/ath9k.conf
Est-ce que ça vaut le coup d'en créer un juste pour y ajouter la ligne 'options ath9k nohwcrypt=1...' ?
De plus, à quoi sert cette ligne exactement ?

Re : Wifi aléatoire Natty 11.04 - D-link DWA-547 - WIRELESS N
Apparement, ça correspond à ce bug : https://bugs.launchpad.net/ubuntu/+sour … bug/735171
Il suffirait d'activer le dépôt "natty-proposed" et de faire une mise à jour vers le noyau 2.6.38-10
J'essaye de ce pas.
Sinon, une autre solution est mentionnée, je cite :
Happily I found a solution:
I use the last tarball from here:
http://linuxwireless.org/en/users/Downl … he_tarball
But each time the kernel is updated, I have to compile it and install it again.

Bonsoir,
Tu peux essayer de changer le cryptage sur ta box pour du WPA 1 TKIP ou mieux, du WPA 2 AES
Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).
