[résolu] wifi ne fonctionne plus après mise à jour

Bonjour,

Suite à une mise à jour de xubuntu8.10 xubuntu9.04, le wifi ne fonctionne pas ou très mal. La carte Wifi est une carte "netgear WG311T". Wicd (actuellement installé) et network-manager détectent le réseau.
Voici le résultat des commandes préconisées:

Re : [résolu] wifi ne fonctionne plus après mise à jour

tu peux rajouter à la fin du fichier /etc/network/interfaces

auto wlan0
iface wlan0 inet dhcp

Je suis un obsédé textuel. J'aime trop le LaTeX.

Merci. Je teste cela, dès que possible.

Re : [résolu] wifi ne fonctionne plus après mise à jour

Après désinstallation de Wicd et réinstallation de network-manager, le wifi semble refonctionner. J'avoue ne pas trop comprendre...:rolleyes:
