Bonjour,
J'ai récemment installer Ubuntu 17.10 à coté de mon Windows et j'ai remarqué que le wifi capté à peine et que c'était très très lent, que ce soit à la fac ou chez moi. Même si je me trouve à coté du modem.
Pourtant sous Windows il n'y a aucun problème.
Si quelqu'un pourrait m'aider ça serait vraiment sympa
