Constamment perdu de la connexion Internet avec le wifi après l'installation Ubuntu 16.04
J'ai un ordinateur portable Lenovo Y700 et j'ai installé Ubuntu 16.04 LTS et j'ai des problèmes avec le Wifi.
La connexion sans fil semble bonne mais je n'arrive pas parfois à me connecter à Internet. Pour le réparer, je le fais ...
service network-manager restart
Cela fonctionne pendant quelques minutes mais plus tard, le même problème et je dois redémarrer encore et encore, et c'est vraiment ennuyeux.
J'ai essayé les solutions données dans cette question similaire mais le problème continue.
Ceci est l'information de mon PC ...

Merci beaucoup.
Je vous suggère de désactiver l'économie d'énergie dans Network Manager. Depuis le terminal:
Sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Ensuite, vérifiez les paramètres du routeur. WPA2-AES est préféré; pas tous WPA et WPA2 mode mixte et certainement pas TKIP. Deuxièmement, si votre routeur est capable de N vitesses, vous pouvez bénéficier d’une meilleure connectivité avec une largeur de canal de 20 MHz dans la bande des 2,4 GHz au lieu de la fréquence automatique 20/40 MHz, bien que cela puisse affecter les vitesses de N. J'ai aussi plus de chance avec un canal fixe, que ce soit 1, 6 ou 11, plutôt que la sélection automatique du canal. Assurez-vous également que le routeur n'est pas configuré pour utiliser uniquement N vitesses; auto B, G et N est préféré.
En fait, dans les données que vous avez fournies, nous voyons dix réseaux, y compris celui auquel vous êtes connecté, qui se trouvent sur le canal 1. Dans votre cas, je suggère, les canaux 6 ou 12 et pas 1.
Redémarrez le routeur et laissez-nous entendre votre rapport.
Si cela est inefficace ou seulement partiellement efficace, installez un meilleur pilote
Sudo add-apt-repository ppa:hanipouspilot/rtlwifi
Sudo apt-get update
Sudo apt-get install rtlwifi-new-dkms
Redémarrez et dites-nous si la connectivité est améliorée.
