Soucis de connexion WiFi : connexion à d'autres réseaux impossible
Bonjour, je vous expose mon problème :
J'ai un pc portable et une freebox,
je peux me connecter chez moi en WEP, sur mon FreeWifi également, ainsi qu'à la fac et à quelques hotspots (MacDo, ..), tout ça avec NetworkManager
Mais, pour tous les autres réseaux, ça marche pas : WEP et WPA chez des amis, tous les FreeWifi captable depuis mon appart ou des lieux publics, tous les réseaux non sécurisés (NeufWifi, bars, etc..), bref pas très utile la Wifi dans ces conditions.
J'ai essayé de me passer de NetworkManager pour me connecter sur un FreeWifi pas à moi, dhcp n'aboutit pas.
Et chez moi, en essayant de me connecter en console, DHCP me trouve une IP mais je ne ping rien du tout, et aucune page web n'est accessible.
voici le résultats des quelques commandes demandées en intro :
