[RESOLU] Wifi instable/Ubuntu 14.04
Bonjour a tous,
Apres une installation toute fraiche de Ubuntu sur un ''lenovo C460'' mon wifi est instable il fonctionne au demarrage et au bout de 5 minutes plus rien, je suis oblige de le redemarrer.
je pense que mon wifi est ok, tout fonctionne a part le lenovo.
Auriez-vous une solution?
Desole je sais qu'il y a deja pas mal de poste la dessus mais rien ne fonctionne chez moi ou plutot moi qui a mal saisie.
j"ai deja lu et cherche rien n'y fait.
Merci ;-)

Re : [RESOLU] Wifi instable/Ubuntu 14.04
Pour donner de la lisibilité à ton post peux-tu s'il te plait mettre le résultat de chaque commande dans les balises codes <> présentes à gauche de l'outil de citation .
Nous mourrons tous .

Re : [RESOLU] Wifi instable/Ubuntu 14.04
Vraisemblablement deux solutions s'offrent à toi .
La première comme décrite dans la documentation suppose de te faire utiliser un pilote plus récent .
La seconde évoquée ici suppose quant à elle d' upgrader ton kernel vers le 3.16 et de réinstaller le driver à partir d' ici .
Cependant dans un premier temps pour éviter de passer par ces étapes nous allons essayer d'enlever la veille de la carte wifi avec cette commande (toujours issue de la doc) :
echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.confEnsuite en redémarrant utilise ton système normalement pour voir si cela résout le problème .
Si cela s’avère infructueux non nous passerons à la mise à jour du pilote et si cela ne fonctionne toujours pas à la mise à jour du kernel ET du module .

Re : [RESOLU] Wifi instable/Ubuntu 14.04
Voila alors cela fait 2 ou trois jours que j'ai essaye la premiere solution, a savoir enlever la veille de la carte wifi et cela a l'air de tenir pour l'instant.
un grand merci a toi spinosiste!
