Problème de portée avec une livebox
Salut, j'ai installé ubuntu sur mon pc hp par soucis de performance.
Mais, un nouveau problème s'ajoute à ma liste, en effet, dès que je quitte mon salon mon pc ne capte plus de connexion alors qu'avec windows
cela fonctionnait.
Mais, ma connexion dans le salon est bonne au niveau de la vitesse.
C'est surtout la portée qui a été fortement réduite.
Merci pour vos réponses.
