Bonsoir à tous.
Je rencontre de puis environ deux semaines des arrêts de connexion wifi, survenant apparemment de manière aléatoire.
Néanmoins, je suis obligé de redémarrer régulièrement NetworkManager, qui semble être le fautif, à coups de :
sudo killall NetworkManager & sudo NetworkManager
Je soupçonne une mise éventuelle mise à jour responsable de ça.
D'après le script wificheck, j'obtiens ceci :

Merci à tous ceux qui me répondront. 🙂
