Absence de portée WiFi [Atheros AR9285]
Bonjour à vous,
J'ai franchis le pas est décidé de passé sous Ubuntu 12.04, en délaissant windows il y a peu. Mon problème est le suivant :
Sous windows, la porté de ma wifi était limité si je n'installais pas un certain driver, le Wireless LAN pilote, d'Atheros. Avec ce driver, aucun problème.
Malheureusement, ce pilote n'est pas compatible Ubuntu. Et ma portée est donc très limité, m'obligeant à me tenir dans la même pièce que ma livebox.
Voici les commandes à saisir, suivit de leurs résultats.

Re : Absence de portée WiFi [Atheros AR9285]
J'ai la même carte Atheros AR9285 et le wifi sous linux fonctionne vraiment nickel (aussi bien qu'avec windows7 si tu veux).
Si tu as des problèmes de connexion tu peux essayer avec iwconfig de réduire le débit ce qui peux stabiliser ta connexion, de jouer sur les paramètres rts...
Pour le reste tu as raison, le wifi devrait pouvoir être dispo dans plus qu'une pièce... mais là tu nous fournit des logs ou tu as 70/70 pour le signal, difficile de se dire que tu as un souci.

Re : Absence de portée WiFi [Atheros AR9285]
Réponse courte : restez dans la pièce où est votre box, achetez un cable, ou restez sous Windows.
Toutes les commandes que vous avez rentrées ne servent qu'à déterminer pourquoi une connexion ne fonctionne pas. Elles ne servent pas à évaluer pourquoi une connexion fonctionne mal - en-dehors du fait que les affirmations du type "internet est lent", etc., sont extrêmement subjectives
Et puis, sincèrement, arrêtons de polluer l'atmosphère avec le wifi, quand il est juste question de parcourir quelques mètres pour se brancher à sa box avec un câble.
Si on pouvait éviter ça...
