reseau wifi vu 1 fois mais depuis plus rien...

Bonjour à tous,

Je suis en train de faire un petit ordinateur retrouvé par hasard pour mon gamin.
Il l'aura dans sa chambre mais à défaut d'avoir mis un routeur et un cable éthernet, j'aimerai lui brancher le wifi via un dongle PEABIRD 54G.

J'ai suivi le tuto trouvé sur le site correspondant au même appareil ( http://doc.ubuntu-fr.org/thomson_wlg_1500a ).
Le dongle est allumé, et au premier redémarrage, le réseau wifi de ma neufbox était présent. J'ai entré ma clé WEP et depuis, plus rien (même pas de réseau FON trouvé qui est pourtant actif lui aussi)...

Merci à ceux qui m'aideront.
