Wifi instable et coupure intermittentes Ubuntu 16.04 [RESOLU]
Bonjour à toutes et à tous.
Voir les résultats du wificheck plus bas.
Ayant récupéré mon pc après réparation touchant le matériel ( changement ventilateur et pâte thermique, pas d'actions effectuées sur les logiciels ), celui recontre une instabilité au niveau de sa connexion au réseau wifi de mon domicile, alors qu'avant cette période d'indispo, il n'y en avait pas. Je n'ai également rien changé à la configuration de ma box pendant ce laps de temps.
J'ai déjà compulsé plusieurs autres fils, mais sans trouver de solution satisfaisante.
J'avais rencontré ce problème par le passé, au moment de la migration vers la dernière version, mais celui-ci s'était réglé du jour au lendemain sans action de ma part.
C'est pourquoi je vous demande votre aide, en profitant de l'un des rares moments de stabilité de la dite connexion ^^
Merci d'avance !

Re : Wifi instable et coupure intermittentes Ubuntu 16.04 [RESOLU]
Bonjour,
Avec les noyaux de série 4.4 , utilisés par les versions Ubuntu 16.04, il est conseillé de désactiver le secure boot !
S'inspirer de la Doc : desactiver_secure_boot
Tu avais regardé cette discussion : forum.ubuntu-fr.org/viewtopic.php?id=1994059
pour la même carte wifi :

Re : Wifi instable et coupure intermittentes Ubuntu 16.04 [RESOLU]
Bonjour Xubu, et merci de ta réponse.
J'étais passé à coté de cette discussion.
Mes excuses pour ne pas avoir cherché suffisamment.
Je fais le test dès que j'ai un moment.

Re : Wifi instable et coupure intermittentes Ubuntu 16.04 [RESOLU]
La manip décrite ci dessous avait été effectuée avec un autre périphérique wifi, donc ne fonctionnait pas, mais après changement de carte et avoir suivi le tutoriel, tout fonctionne. Le sujet est donc résolu.
