Pb déconnexion wifi

nicofo

Bonjour,

j'utilise un wifi Linksys usb - driver rt2570 : le pb est qu'après un tps aléatoire (qq minutes ou qq heures) il se déconnecte !
Lorsqu'il est déconnecté, iwconfig et ifconfig me renvoient bien les bonnes infos (c'est tjs bien configuré).

Le pb est qu'il ne se reconnecte pas automatiquement (testé en IP fixe et en dhcp). Je dois faire un ifdown / ifup +reconfig de l'interface manuellement !!

Pour info : /var/log/messages

# tail  /var/log/messages -n 60

Personne pour m'aider ?

voici les différences entre un "iwconfig rausb0" lorsque tout va bien et lorsque ça se déconnecte intempestivement :

# iwconfig rausb0 (DÉCONNECTÉ INTEMPESTIVEMENT)
rausb0    RT2500USB WLAN  ESSID:"xxxxxxxxxxxxxxxx"  
          Mode:Managed  Frequency=2.412 GHz  Bit Rate=36 Mb/s   
          RTS thr:off   Fragment thr:off
          Encryption key:xxxxxxxxxxxxxxxxxxx   Security mode:open
          Link Quality=80/100  Signal level:-70 dBm  Noise level:-212 dBm              <= BIZARRE ! ? ! ?
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0



# iwconfig rausb0        (VA BIEN)
rausb0    RT2500USB WLAN  ESSID:"xxxxxxxxxxxxxxxxxxxx"  
          Mode:Managed  Frequency=2.462 GHz  Access Point: 00:06:25:FA:EA:75   
          Bit Rate=54 Mb/s   
          RTS thr:off   Fragment thr:off
          Encryption key:xxxxxxxxxxxxxxxxxxxxx   Security mode:open
          Link Quality=79/100  Signal level:-72 dBm  Noise level:-206 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

==> la seule différence est que l'access point a disparu.
D'autre part, il est bizarre qu'il dise "link quality=80%" alors qu'il est déconnecté !

J'ai également comparé les ifconfig rausb0 dans les 2 cas ==> eux sont semblables.
J'ai essayé à peu près toutes les cmd possibles (euh... qq unes du moins) avec iwconfig ==> ça change rien !
j'ai réessayé de reconfigurer ifconfig à la main : "ifconfig rausb0 inet 192.168.1.10 netmask 255.255.255.0" ==>CHANGE RIEN
==> seule solution trouvée jusqu'à présent : "ifconfig rausb0" down puis "up"

D'autres idées ? Merci d'avance

Il y a peut-etre un rapport avec iptable ?? En effet, quand j'ai eu des pb de déconnexion (mais que j'ai résolu via ifconfig down/up et route...), lorsque j'éteins mon PC, if se bloque sur "Unloading iptables modules" ==> je dois faire un hard reset.

Embêtant tout ça...

RT2500USB

Tu peux me rappeller le retour de la commande lsusb pour ce matériel?
Tu utilises la version rt2x00 du driver!

Salut,

Non, je n'utilise pas rt2x00 (va pas chez moi) mais kmod-rt2570-1.1.0.cvs20061120-5.2.6.18_1.2849.fc6

C'est ce qui m'a fait croire cela!

Ah oui pas tres parlant quand même! pour le lsusb!

Et est ce que tu avais essayé le rt2500? Il est possible qu'il fasse fonctionner les modèles usb un peu ancien...

Sinon, j'ai pas testé rt2500
