Impossible de se connecter au réseau wifi domestique

Bonjour,
Je n'arrive plus a me connecter soudainement à mon réseau wifi sous UBUNTU 16.04 LTS. (Durant ce temps mon Raspberry Pi est lui connecté sans problème. Coté réseau wifi le système semble fonctionné)
J'espère que ma préparation pour poser cette question (ma toute première!) est correcte . J'ai rassemblé les éléments sur mon équipement et ma connexion wifi avec le script Wificheck. Voici le (long) résultat copié ci dessous.
Mon réseau wifi personnel est HOME07 et ma connexion filière ethernet fonctionne parfaitement.

Salut,

Il manque juste la mise en forme : peux tu éditer le message et utiliser les balises code <> pour les retours de commande?

Re : Impossible de se connecter au réseau wifi domestique

Cette solution pour une carte wifi identique à la tienne :

Network controller [0280]: Intel Corporation Centrino Wireless-N 1000 [Condor Peak] [8086:0083]

Bonjour !
Merci Toutafai !
J'ai enfin résolu le problème à l'aide de Varunendra sur le forum anglophone. Tu étais très proche de la solution, il fallait finalement remplacer le contenu du fichier (et pas ajouter à la fin comme je l'ai fait). Et il fallait aussi modifier un paramètre concernant l'utilisation simultanée du Wifi et du Bluetooth dans mon cas. Voici la manipulation exacte que j’ai utilisée :

echo "options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf

A priori, le paramètre "swcrypto" ne semble avoir aucune incidence sur ma connexion, mais je le laisse par simple précaution.
Le détails des options est expliqué très clairement ici (en anglais) : http://ubuntuforums.org/showpost.php?p=12943350

Merci encore pour toute ton aide !
