J'ai un tout nouveau HP Stream 11-r001nd. Je parviens à me connecter à mon réseau, mais il est trop lent. Même lorsque je mets mon ordinateur portable et le routeur l'un à côté de l'autre, il est trop lent de regarder une vidéo youtube (si la page Web de youtube se charge du tout). Sur Windows 10, ce problème n'existait pas.
Dans cette vidéo youtube, il montre qu'en utilisant la version 14.10, la vitesse était acceptable. Mais cette version n'est plus prise en charge.

Cela semble indiquer qu'un micrologiciel incorrect est chargé sur un périphérique USB sans fil.
En relation :Je ne trouve pas les packages VPN sstp avec Ubuntu 16.04 LTS ?Cependant, votre problème réel semble être que la carte Realtek Wifi RTL8723be ne fonctionne pas correctement. Suivez les étapes indiquées dans la solution.
Si cela résout votre problème, veuillez cliquer sur la coche à gauche pour montrer que votre problème est résolu. Sinon, republiez la sortie du script wifi, de préférence après avoir résolu les deux autres erreurs. Le premier devrait disparaître après un redémarrage. Le second n'apparaîtra pas si vous retirez le périphérique USB avant d'exécuter le script.
J'ai examiné les résultats de votre deuxième exécution du script sans fil. Regardons quelques fragments :

Cela montre que le brouillage provient d'un point d'accès appelé série HP-print-C3-Deskjet 2540. Je suggérerais de changer le canal RF du point d'accès ou de l'imprimante afin qu'ils soient sur des canaux différents. Pour le moment, ils sont tous les deux sur le canal 1. Les seuls autres canaux utilisés sont 6 et 7, vous avez donc l'embarras du choix.
L'imprimante sert de point d'accès car vous avez appuyé sur le bouton sans fil direct (voir page 53 du manuel d'utilisation). Vous devez avoir connecté votre imprimante à votre routeur en suivant les instructions de la page 49 du manuel. Le manuel d'utilisation est disponible en ligne ici
