RESOLU - Wifi sur Cubox...

dummy@example.com (AozRoon) — Thu, 05 Apr 2012 19:36:09 +0000

Salut,

J'essaye de configurer un accès wifi sur une Cubox (ordi ARM --> http://www.solid-run.com/mw/index.php/C … ification)
La machine tourne un ubuntu 10.04, noyau 2.6.32.59

uname -a
Linux cubox 2.6.32.59-dove-5.4.2 #32 PREEMPT Tue Apr 3 05:11:12 MDT 2012 armv7l GNU/Linux

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04.4 LTS"

lsusb, lspci & lshw ne renvoient rien (ARM ?).

~$ lsmod
Module                  Size  Used by
binfmt_misc             6129  1

sg                     15785  0

J'utilise une carte wifi usb d-link dwa-131.

Elle a l'air reconnue et a l'air de se connecter à mon réseau wifi, mais je n'ai pas de réseau. Par exemple, mon routeur ne répond pas au ping... alors que sur l'interface du routeur je vois bien la cubox, son adresse MAC et l'IP qui lui a était attibuée...

Des pistes ?

EDIT : en rebootant sans connexion ethernet le problème s'est réglé tout seul
