Je réussis de temps à autre à me connecter à la distance voulue (depuis le lit) en insistant sur l'applet d'Xfce, mais même une fois obtenue, la connexion se coupe après quelques minutes. Avant de se couper l'outil information de l'applet signale une vitesse de connexion de 1Mb/s.

L'outil iwlist ne parvient pas tout le temps à afficher un scan du wifi, alors qu'il apparait dans l'applet Xfce de network-manager.


J'hésite à desinstaller network-manger pour essayer un autre gestionnaire de connexion. Je ne sais pas non plus par le quel le remplacer.

Peut être auriez-vous une solution à ce problème et / ou une suggestion pour remplacer network-manager.

Re: Distance limite de connexion wifi

Hello pam547, je ne pense pas que changer de gestionnaire de connexion puisse résoudre ton problème.
J'ai cherché les caractéristiques de la carte wireless sans succès
Peu importe le nom de la carte du moment que l'on a identifié le chipset (Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01))
Je suppose que sous wouindow$ tu ne rencontrais pas ce problème, cela est dû au fait que les fabricants optimisent les pilotes de leur matériel uniquement pour un seul système d'exploitation comme celui cité ci avant. Nous utilisateurs de Linux sommes des laissés pour compte et souvent, nous devons pas mal bricoler afin de pouvoir faire fonctionner ce genre de matériel. Bref la base installée d'utilisateur Linux ne représente qu'une infime partie du marché et dès lors cela n'intéresse pas les fabricants. Seul quelques uns d'entre eux développent des pilotes Linux dignes de ce nom.
Il faut savoir aussi que la portée du wifi en intérieur dépend non seulement de la distance entre le modem ou la box et le pc, mais aussi des matériaux dans lesquels a été conçu le bâtiment. Il est clair que des planchers ou des cloisons en bois laisseront passer les ondes plus facilement que des planchers en béton ou des cloisons en parpaing.
Néanmoins il faut savoir que wifi communique sur une bande de fréquence appelée canal. Voila ce que je te propose de faire comme essais pour optimiser ta liaison. Tout d'abord il faut aller dans les paramètre wifi (ou sans fil) de la box, si les paramètres du canal est sur "automatique" je te propose de faire des essais en essayant à partir du canal 10 et en descendant progressivement d'un canal jusqu'au meilleur résultat.
C'est un travail de longue allène car entre chaque essais il faudra stopper et relancer network-manager, voici la commande pour stopper et relancer celui-ci

Code : Tout sélectionner

sudo restart network-manager
.
Et bien sûr tu nous tiens au courant.

Merci pour ta réponse pingus,

Je capte à nouveau facilement le wifi depuis la dernière "dist-upgrade".

À l'occasion je creuserai cette histoire de canaux. Merci encore.
