[Resolu]-Wifi alléatoire
Bonjour,
En dépannage, j'utilise un vieux PC HP Compack 6010p.J' ai installé Xubuntu en i386. Lors de l' ouverture de la session, la wifi est déconnecté et, malgré plusieurs tentatives de connections, elle ne démarre pas. Un redémarrage du PC arrive parfois à démarrer cette wifi. J' ai envoyé la commande conseillé et je vous joins le résultat.

Re : [Resolu]-Wifi alléatoire
Bonjour,
Est-il possible de changer le chiffrement de la Box en WPA2 ?

Re : [Resolu]-Wifi alléatoire
Bonsoir,
En fait, je me suis contenté de passer les commandes de chibbata. Après, la wifi fonctionnant, j' ai donc ouvert le fichier
sudo mousepad /etc/modprobe.d/iwl4965.confet j' ai rentré la ligne
options iwl4965 11n_disable=1Depuis, tout fonctionne.
Sa fait vraiment plaisir de récupérer une machine en état.
Cordialement

Re : [Resolu]-Wifi alléatoire
Autre question, le Bluetooth fonctionne t-il sur cet ordi ?
