[Résolu] Problème connexion wifi sous Ubntu 14.10
Bonjour,
Je reposte mon problème dans la bonne section du coup :
Je viens d'installer la version 14.10 et je ne peux pas naviguer sur internet. Auparavant, aucun soucis de connexion sous 13.04.
Branché en ethernet, je suis connecté sans soucis.
Câble ethernet débranché, je peux accéder à la liste des réseaux sans fil disponibles, je me connecte également à mon réseau. C'est uniquement lorsque je lance un navigateur (essayés : Firefox, Chromium, Chrome) que je n'ai pas accès à internet.
Je précise que mes connaissances techniques en informatique sont assez limitées 
Voici donc les réponses aux commandes suggérées :

Re : [Résolu] Problème connexion wifi sous Ubntu 14.10
Problème résolu, assez simplement en fait, réponse trouvée ici.
Connexion lente à cause d'un Bit Rate mal configuré
Si vous remarquez que votre connexion Wi-Fi est anormalement lente et que cela ne vient pas de votre matériel (carte ou AP) et avant de réinstaller, recompiler…d'autres pilotes :I. Vérifiez le Bit Rate de la carte :
iwconfig
Si vous voyez Bit Rate=1Mb/s alors tapezsudo ifdown wlan0 sudo iwconfig wlan0 rate 54M sudo ifup wlan0(ou ra0 suivant le nom de votre interface)
Enfin, faites "iwconfig" pour vérifier qu'il vous met bien Bit Rate=54Mb/s . Voilà qui devrait aller mieux !
pour que ca reste permanent : Ajoutez dans /etc/rc.local (avant la ligne exit 0)
ifconfig wlan0 up iwconfig wlan0 rate 54Mon redémarre et le tour est joué!
