Intel 3945 et Wifi "lent"
Bonjour,
Je suis sous Hardy et je me bats avec le wifi.
Grâce à l'aide de gentils membres ma connexion est aujourd'hui stable, mais le débit est faible.
Est-ce qu'il y a une manip spéciale à faire pour optimiser le chipset Intel 3945 qui équipe mon portable?
Merci par avance.
Ps : comment peut-on choisir le canal? Ma box est réglée sur g - canal 8
Dans les situations critiques, quand on parle avec un calibre bien en pogne, personne ne conteste plus. Y'a des statistiques là-dessus!

Bonjour, un petit tour par la pour une vue d'ensemble :
http://forum.ubuntu-fr.org/viewtopic.php?id=141183
dans iwlist tu verras les réseaux que ton systeme capte, tu pourras choisir un channel non occupé entre 1 et 11

Re : Intel 3945 et Wifi "lent"
Bonsoir it7,
J'ai fait un iwlist scan et comme les voisins sont tous sur 1, 10 ou 11, j'ai choisi le 8.
Je renvoie les commandes :

J'espère que vous pourrez me filer un petit coup de main et je vous en remercie d'avance.

Re : Intel 3945 et Wifi "lent"
Bonsoir,
J'ajoute qu'avec ma box précédente j'avais eu des soucis et que toutafai m'avait donné un grand coup de main (je l'en remercie encore) et je donne le lien vers l'échange que nous avions eu à ce moment là, si cela peut vous aider.

Re : Intel 3945 et Wifi "lent"
Bonsoir it7,
J'ai suivi tes conseils, et j'ai appliqué le point 2 du tuto que tu m'as donné en référence.
Un fait marquant : avant quand ma machine démarrait, elle se plantait sur une histoire de cups. Là démarrage rapide sans passer par l'écran noir habituel. Pourquoi? J'en sais rien. Si tu as une explication ....
Une question : pourquoi est-ce que la connexion m'est toujours proposée vers une box autre que la mienne? Bon, d'accord, je choisi la mienne et tout marche, mais une chèvre est parfois un peu tatillone 
.
Et le bon pilote pour ce chipset, c'est iwl3945 ou ipw3945?
Merci pour ton aide.

Re : Intel 3945 et Wifi "lent"
Bonjour, un des deux marche peut être mieux ? , tu parles du channel 8 mais tu es sur le channel 6 , pour le channel tu le fixes avec :
wireless-channel 6
car il y en a un autre sur le premier channel au scan

Re : Intel 3945 et Wifi "lent"
Bonjour it7,
D'accord, mais mon fichier /etc/network/interfaces
auto lo
iface lo inet loopbackest pour le moins vide.
Mes déclarations manuelles on disparus lors de la manip #2# du tuto pour Intel 3945.
Donc, je me dis que les paramètres réseau ne sont plus gérés par ce fichier, mais par lequel? Peux-tu m'aider?
Merci d'avance.

Re : Intel 3945 et Wifi "lent"
Bonjour, ajoutes ça dans ton fichier /etc/network/interfaces :
auto eth1
iface eth1 inet dhcp
wireless-key TumetsalaplacetaclefWEP
wireless-essid TumetsalaplacelenomdetonRéseau
wireless-channel 6
ensuite tu sauvegardes puis
sudo /etc/init.d/networking restart
