Wifi fluctuante sous Ubuntu 16.04 LTS
Wifi fluctuante sous Ubuntu 16.04 LTS
Bonjour,
Mon installation comporte une box et un routeur WRT54GL. Ces équipements se trouvent à 3 ou 4 mètres de mon ordi.
Lorsque je me connecte en Wifi avec mon téléphone le signal est maximal. Network Manager m'indique péniblement 2 niveaux.
J'ai essayé avec une clé USB. Idem.
Il y a un truc qui cloche, c'est sure.
Si quelqu'un pouvait m'aider, d'avance merci.
Voici le contenu de mon wificheck :

Bonsoir,
L'ordinateur est de marque Asus ?

* ChouchanFamily Infra 11 54 Mo/s 42 ▂▄__ WPA1 WPA2Modifier, le chiffrement de la Box ou du routeur, comme le conseille toutafai dans de nombreuses discussions :
moko138 a écrit :
Entretemps, j'ai retrouvé ce message ./viewtopic.php?pid=21563767#p21563767 de toutafai (8/2016) :
Ta box utilise un double chiffrement (al 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
