Desolé pour la longueur 😉
En fait, la connexion wifi ne se fait que si le cable ethernet est branché, sinon il ne detecte aucun reseau,
et la connexion reseau n'est pas detectée dans les preferences reseaux....
Pour info mon reseau est le SFR 6FE8, le reste c'est le voisinage, sauf l'imprimante hp qui est chez moi aussi.
