Pb connexion Wifi 3com (Atheros) connec OK (?) ping KO
bonjour à tous !
Je rencontre un petit pb de connexion wifi sur mon (vieux) laptop ASUS M6, aevc une carte PCMCIA 3com (chip atheros)
la connexion au routeur wifi semble ok d'après wicd et iwconfig / ifconfig ,
le moniteur syst indique du trafic (??)
mais le ping est KO "host unreachable". étonnant ! je pense que je suis proche du but 
néanmoins ...
peut etre y-a-t-il conflit avec la carte interne (miniPCI chip TI acx111 que je n'arrive pas non plus à faire marcher ....)
les manips "non-standard" que j'ai effectuée depuis l'install :
-désactivation du module acx (qui rendait instable le syst (lag ) )
-désactivation de l'ipv6 (en pensant que cela aiderait ?)
-désinstallation du network menager /install de WICD
merci pour toute aide ! 
voici les commandes dépannage , j'ai rajouté à la fin netstat -i et le ping qui ne marche pas

Re : Pb connexion Wifi 3com (Atheros) connec OK (?) ping KO
Bon , un petit passage par wifi-radar ne donne pas plus de résultats,
j'ai oublié de préciser que l' AP ne devrait pas être la cause directe du problème, sachant que un autre PC y est connecté , et que je vois mon PC ubuntu connecté aussi ...
comme la connexion wifi semble se lancer, je penche pour un pb IP... routage ?
merci d'avance pour toute aide

Re : Pb connexion Wifi 3com (Atheros) connec OK (?) ping KO
STOP ! que les dizaines de férus de réseau qui s'appretaient à m'aider(si , si !) passent à autre chose, problème résolu, et du , bien sûr, à une grosse erreur de ma part, sur la clé (boulet !)
j'ai été leurré par WICD qui m'indiquait "connected" mais je n'etais pas "associated" avec l'AP
bref , cela fonctionne très très bien
