Guten Abend,
ich habe ein MacBookpro (2011) mit Ubuntu 16.04 LTS. Ich habe (mal öfter, mal weniger oft) Verbindungsabbrüche (die Verbindung zum Wlan bleibt, Internet funktionert nicht) zum Wlan. Nach Trennung und Neuverbindung funktionert die Verbindung wieder. Ich poste hier mal einfach die Ausgaben nach folgendem Post https://forum.ubuntuusers.de/topic/vor-dem-erstellen-eines-neuen-beitrags-bitte-/. Kernelversion
