Bonjour,
J'éprouve beaucoup de difficultés à me connecter au wifi sur un ordinateur 1er prix d'Auchan SELECLINE.
Après bien des déboires (j'ai effectué pleins de manips décrites dans les forums), il m'a semblé que la bête s'est bien connectée au wifi et j'ai eu accès à internet.
Mais après l'avoir redémarrer, impossible de me connecter.
J'ai fait le wificheck :

Les commande ifconfig et nm-tool ne sont apparemment pas installées, mais sans wifi, je ne vois pas comment je peux faire !
Je vois pas du tout d'où peut venir le problème, ni même comment ça a pu marcher une fois.
