re bonjour, le wifi fonctionnait correctement depuis quelques temps jusqu'à ce que je déménages et que les mêmes problèmes que précédemment reviennent (je ne capte pas la wifi à plus d'un mètre de la box). la box est une redbox, je l'ai configuré pour qu'elle ne soit que en WPA2, j'ai repris tout les conseils qui m'ont été donné plus haut mais ça ne marche toujours pas...
quelqu'un aurait une nouvelle idée ou un élément que j'ai loupé?
