Re : wifi faible sur samsung
Bonjour,
Wireless Properties
WEP Encryption: yes
WPA Encryption: yes
WPA2 Encryption: yesModifier, le chiffrement de la Box , comme le conseille toutafai dans de nombreuses discussions :
Le 14/11/2016, moko138 a écrit :
Entretemps, j'ai retrouvé ce message ./viewtopic.php?pid=21563767#p21563767 de toutafai (8/2016) :
Ta box utilise un double chiffrement (à la fois du wpa1 et du wpa2), c'est certainement la source de ton problème.
Connecte toi sur l'interface d'administration de ta box et change moi cela pour
soit que du wpa1 TKIP,
soit que du wpa2 AES
(ne pas oublier d'enregistrer les changements sur ta box),
Une fois que ce sera fait, tu ne devrais plus avoir de déconnexions
