[RESOLU] wifi freebox / No DHCP offer => repasser CANAL 11

rmy · Le 24/02/2008, à 17:20

Description "succinte" du problème :

Je n'arrive plus à connecter mon portable en wifi à ma freebox. Il me semble que celle-ci refuse d'adresser l'IP (no DHCP offer).

Tests croisés :
cet ordi (VAIO VGN TX1) en dual boot ne se connecte pas à la freebox ni sous windows, ni sous linux.
ce même ordi se connecte sans problè chez les voisins (exit le problème matériel)
un autre ordi sous windows se connecte à la freebox
un autre portable en dualboot se connecte dans les deux cas à la freebox
Avec 1 live CD (hardy alpha 5) je n'arrive pas non plus à me connecter.

Symptômes : nm-applet demande en boucle la cle WEP (que j'ai réduite à 0123456789 pour simplifier les tests et éviter les soucis du WPA)

Plus : wicd et wifi-radar n'y changent rien.

EN un mot : HELP !!!

Les tests décrits dans le post-it sont reportés ci-dessous, effectués à partir du livecd, NB : je suis connecté sur le réseau des voisins pour poster.

ubuntu@ubuntu:~$ cat /etc/network/interfaces

sauf que... c'est sur le live CD...
Heureusement, comme j'ai bien suivi la doc dans le désespoir, pour mon fichier interfaces perso :

ubuntu@ubuntu:~$ cat /media/disk-1/etc/network/interfaces
auto lo
iface lo inet loopback

enfin :

ubuntu@ubuntu:~$ uname -r -m

pour le live hardy, et pour la version d'usage courant :

ubuntu@ubuntu:~$ cat /media/disk-2/grub/menu.lst | grep generic

Une idée Doc ?

RESOLU seul...

IL semblerait que chez free, quand bien même la console d'administration propose tous les canaux du 1 au 13, il ne faille utiliser que le 11 (dixit la hotline, mais la hotline ne parlait pas français, n'a pas compris la moitié de ce que je leur ai dit et vice-versa, ne m'explique pas pourquoi ça fonctionnait encore la semaine dernière sur le canal 1 et ne sait pas pourquoi ça ne fonctionne pas sur le canal 3... Bravo la nouvelle hotline de free)
