probleme connexion wifi

bonjour
j'ai un probleme avec mon ordinateur qui marche sous ubuntu , quand je me connecte sur le wifi cela marche tres bien sur l'ordinateur sauf que les autres ordinateurs de la maison qui sont sous windows n'arrive pas quand a eux a se connecter a internet comme si je pompait tout le wifi de la maison et quand je me deconnecte tout redevient a la normal
j'espere que vous avez des solutions
merci
