pas de wifi RTL8723BE- MAJ 16.04 à 18.04 Lts

sleer

Bonjour
je viens à vous car j'ai installé récemment ubuntu 16.04LTS mais je n'arrive pas à me connecter en wifi. Il m'indique toujours que le périphérique n'est pas prêt. Pourtant le réseau wifi est activé
J'ai essayé pas mal de commande depuis 2 semaines et surtout lu des messages mais rien n'y fait. Donc j'en reviens à vous.

MErci de votre aide

Bonjour,

Peux-tu donner tes infos : Configuration wifi ?

tu peux utiliser le : [doc]wificheck[/doc]
Nota :Vous trouverez ensuite un fichier wificheck.log dans votre répertoire personnel, collez l'intégralité de son contenu dans votre discussion.

en te servant du : Retour utilisable de commande

sleer

En recherchant encore et encore j'ai modifier les parametres de la box sfr et suvi un autre message:
https://forum.ubuntu-fr.org/viewtopic.php?id=2007230

merci

sleer

finalement cela ne marche pas et reviens au même après l'avoir redémarré.
Il me marque toujours que mon périphérique n'est pas pret.
Quand j'avais réussi deès que je m'éloignais de ma box, il ne recevait plus rien.

donc toujours pas résolu, je commence à désespérer de devoir utiliser que windows!!!

maintenant mon wifi refonctionne mais je n'arrive toujours pas à m'éloigner de 2 m de ma box. Le wifi se déconnecte de suite. Je n'y comprends rien car avec mon ancien pc avec la même version et la même box fonctionnait très bien même à 10m.
Que se passe t il?

xubu1957

Tu as une carte wifi paramétrable.

Direction ce fil : [résolu] installation wiifi carte realtek . RTL8723BE

sleer

merci encore xubu1957
effectivement tu as raison mais les parametres que tu m'as donné n'y font rien. Je n'y comprends rien car cela a l'aire de fonctionner pour les autres.
J'ai bien fait les modif dans gksudo gedit /etc/modprobe.d/rtl8723be.conf
et enregistrer la commande: echo "options rtl8723be fwlps=0 ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf.

xubu1957

Il faut en tester d'autres : forum.ubuntu-fr.org/viewtopic.php?pid=21715974#p21715974

Bonjour

j'ai essayé hier ces paramètres mais rien n'y fait dès que je m'éloigne de ma box, le wifi déconnecte. Pourtant cela n'arrive pas avec Windows. Comment est ce possible?

xubu1957

Bonjour,

Il faudrait trouver le bon paramétrage.

Changes ton titre : pas de wifi RTL8723BE- installation ubuntu 16.04LTS pour attirer l'attention d'utilisateurs de cette carte.

Donnes aussi le nom exact de ton HP-Notebook pour essayer de trouver quelque chose sur le net.

Je me demande aussi, si le noyau 4.8 prend bien en charge cette carte wifi.

sleer

Merci xubu1957
je viens de changer le titre et je regarderai le modele de l'ordinateur afin de l'indiquer.
Si le noyau ne prend pas en charge ce type de carte cela va être gênant

xubu1957

Je n'émets qu'une hypothèse, je lisais cela ce matin :

00b00nt00 a écrit Kernel 4.10 doesn't play nicely with the Realtek adapter in my HP Stream 11. Wifi connects, then stalls in Firefox. Oddly enough, I'm able to download updates via the terminal. Unfortunately, kernel 4.4 in 16.04 doesn't support my Stream well, so 16.10 is the only option for me.

Kernel 4.10 ne fonctionne pas bien avec l'adaptateur Realtek dans mon HP Stream 11. Wifi se connecte, puis se bloque dans Firefox. Curieusement, je peux télécharger les mises à jour via le terminal. Malheureusement, le noyau 4.4 en 16.04 ne supporte pas mon flux bien, donc 16.10 est la seule option pour moi.

Jeremy31 a écritIf the Realtek wifi is an rtl8723be, the ant_sel parameter of the module is important with the newer HP laptops

Si le wifi RealTelk est un rtl8723be, le paramètre ant_sel du module est important avec les nouveaux ordinateurs portables HP

dans Wifi not connecting in Ubuntu 17.04 Beta

xubu1957

Dans : solved> realtek RTL8723BE PCIe Wifi adapter not working.

Some newer HP laptops use only one antenna with the rtl8723be, the following code should help you set the ant_sel parameter to the correct antenna
Certains ordinateurs portables HP récents utilisent une seule antenne avec le rtl8723be, le code suivant devrait vous aider à régler le paramètre ant_sel sur l'antenne correcte

sudo modprobe -r rtl8723be

sudo modprobe rtl8723be ant_sel=1

iwlist scan | egrep -i 'ssid|quality'

Then we check the second option to find which one works better
Ensuite, nous vérifions la deuxième option pour trouver celle qui fonctionne le mieux

sudo modprobe -r rtl8723be

sudo modprobe rtl8723be ant_sel=2

iwlist scan | egrep -i 'ssid|quality'

If ant_sel=1 is better
Si ant_sel = 1 est meilleure

echo "options rtl8723be ant_sel=1" | sudo tee -a /etc/modprobe.d/rtl8723be.conf

If ant_sel=2 is better
Si ant_sel = 2 est meilleure

echo "options rtl8723be ant_sel=2" | sudo tee -a /etc/modprobe.d/rtl8723be.conf

Penses à redonner les résultats des essais avec la commande :

iwlist scan | egrep -i 'ssid|quality'
