pas de wifi RTL8723BE- MAJ 16.04 à 18.04 Lts

sleer

bonjour

Je reviens à vous car suite à un problème et une réinstallation d'ubuntu; je n'ai de nouveau plus accès à internet via le wifi.
J'ai essayé les commandes du dernier poste mais cela ne fonctionne pas.
Pourriez vous m'aider s'il vous plait
