Bonjour, essayer ceci dans un premier temps dans un terminal:

sudo ifdown wlan0

Oui j'avais déjà esseyé et apparement wlan0 n'est pas configuré

Merci beaucoup, ça fonctionne, les pages internet se charge a une vitesse normale cependant, la vitesse de telechargement est bizarrement toujours aussi lente (ne dépasse pas les 30kB/s alors que j'ai du 5mega).

Re : Wifi lent ubuntu 8.04

Merci.

Pour le dns j'ai juste changer ce que j'avais mis avec ceux indiquer sur le lien que tu m'as passer. Est-ce que je dois faire tout ce qui est indiqué sur le site ou je devais juste changer les adresses dns?

Pour l'instant ça ne fonctionne pas mieux
