Penses à modifier, le chiffrement de la Box , comme le conseille toutafai dans de nombreuses discussions :

Le 14/11/2016, moko138 a écritEntretemps, 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

AlainJ

Merci,
cette modification n'aura pas d'impact sur les autres équipements connectés à ma box?

xubu1957

Tu as quoi comme équipements ?

Ordis, imprimantes, tablettes ?

As-tu une notice de ta Box avec une documentation relative au chiffrement du wifi ?
(edit)
voir : gerer-wifi-interface

AlainJ

J'ai bcq d'équipement connectés:
TV, tablette, smartphone Samsung + PC portable

J'ai regardé le chiffrement de ma box:
actuellement c'est réglé sur:
système : WPA (PSK) avec type de clés : TKIP et AES

On peut aussi opter pour système chiffrement : WPA2 ou WPA / WPA2 avec type de clés TKIP et AES, ou TKIP ou AES

Sinon tout ça, c'est du charabia pour moi :-)

xubu1957

Bonjour,

Essaies :

sudo ifconfig wlp2s0 up

xubu1957

Et pour comprendre le charabia : wikipedia.org/wiki/Wi-Fi_Protected_Access

AlainJ

aucune réponse

xubu1957

Ton noyau :

4.4.0-31-generic x86_64

n'étant pas le plus récent , lances les mises à jour :

sudo apt update

sudo apt full-upgrade

et redémarrage.

AlainJ

Faut-il une liaison Internet pour ces màj?

xubu1957

Oui, il faut être branché en Ethernet !

AlainJ

les màj sont effectuées

Le double chiffrement empêche la connexion wifi pour l'ordi Dell.

Je n'ai pas d'autre solution que celle de toutafai, donnée au message 2 !

AlainJ

ça marche,
merci beaucoup 🙂
