(encore) un problème de wifi (qui se déconnecte sans raison)
Messieurs-dames bonjour,
Nouvel arrivé dans les terres du libre, j'ai depuis 10 jours une machine sous Ubuntu, et je fais face à quelques récalcitrances de la part de ma wifi.
Pour expliquer le problème en quelques mots : ma connexion internet se coupe fréquemment (enfin ca se déconecte au bout d'un temps aléatoire entre 2 minutes et deux heures). A chaque fois le signal wifi n'a pas bougé dans le network manager, je suis toujours sur ma box, et néanmoins pas moyen de faire quoique ce soit à ce moment la sur internet (que ce soit sur mozilla ou chromium, ou téléchargemnt de paquets, tout est bloqué).
Chaque fois, je suis obligé de redémarrer mon ordi, et ca remache sans problème, jusqu'à la coupure suivante.
Voici les test wificheck (fait pendant que ca marchait pas) :

Merci d'avance à tous ceux qui se pencheront sur mon problème.
Sorry for the long post, comme disent nos amis anglosaxons.

Re : (encore) un problème de wifi (qui se déconnecte sans raison)
J'ai trouvé la solution à mon problème ici.
Si jamais quelqu'un a le même type de problème avec la même carte wifi : Realtek rtl8723be je lui conseille d'aller y jeter un œil.
Il suffit de rentrer cette ligne dans le terminal et de redémarer la machine :
echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.confEn gros il s'agit d'enlever une sorte de parametre de veille de la carte wifi préconfiguré
