Internet lent

Bonjour,
Suite au passage de 11.04 à 11.10 ma connexion wifi est devenue anormalement lente.
J'ai téléchargé et installé par ethernet les paquets et mises à jour mais aucun changement.

Re : Internet lent

Bonjour Chnapy,

Je rencontre le même problème que toi à savoir un ralentissement (voir blocage) de ma connexion wifi. Je dispose d'un Samsung R610 qui fonctionnait parfaitement avec Natty mais qui après la mise à jour à Oneiric 11.10 pose problème.
As tu résolu ton problème et si oui comment ?

Merci

Re : Internet lent

tapes ces 2 commandes dans le terminal

sudo rmmod -f iwlagn

sudo modprobe iwlagn 11n_disable=1

si le wifi fonctionne normalement et pour rendre la manip ci dessus permanente

gksudo gedit /etc/modprobe.d/iwlagn.conf

une page blanche s'ouvres,ecris cette ligne
options iwlagn 11n_disable=1

enregistres et quittes gedit
