impossible de se connecté en wifi

[R a M u S]

salut à tous,
2° post sur ce forum pour 2° problème :
je n'arrive pas à me connecter à internet en wifi depuis chez moi alors qu'au boulo ça marche.
avec un autre pc en xp pas de problème de wifi.
sous ubuntu je choisi mon réseau je tape ma phrase secrète et là il indique que je suis connecté mais je peux pas aller sur internet, il me redemande sans cesse ma clé.

merci d'avance

Re bonsoir

Avec les seules les indications que tu donnes il n'est pas possible de te répondre facilement

Cela dépends du système de protection - le wpa peut poser des difficulter sur feisty

tu trouveras quelques pistes (et un mini tuto) au bas de ce post

ok je viens de lire le tuto.
je te donnerais bien plus d'infos mais je ne sais ce que j'ai comme carte wifi (ha la honte...) et je sais pas ou regarder ça depuis feisty....

Dans une console

sudo lshw

Ou en mode graphique

sudo apt get install hardinfo

Voilà, là c'est suffisant.
Tu as les bons drivers dans ta n'Ubuntu ? Est-ce que tu accèdes à Internet autrement depuis celle-ci ? (genre est-ce que /etc/resolv.conf et autre est déjà renseigné ?)

[R a M u S]

aucune idée, j'avoue ne pas comprendre ta question... lol

en tout j'accède à internet en me branchant sur ma freebox (si c'est ça ta question)

[yostral]

Tu dis que ça marche au boulot. Mais avec ton ordi sous ubuntu aussi ? C'est le même qui ne fonctionne pas chez toi ?

Normalement oui (pour répondre à Athanor1), ton chip wifi est très bien supporté sous Ubuntu.

[R a M u S]

oui au boulo je peux me connecté mais pas chez moi (avec le même pc sous ubuntu).
j'ai testé avec d'autres pc sous xp chez moi et ça marche. par contre même problème avec un mac.

salut

d'abord, en tout premier lieu, enlève tout cryptage de ta Freebox ( ni WEP, ni WPA ) : essaie de te connecter et si ça marche, remets d'abord le WEp puis le WPA.
