Hallo zusammen,
auf meinem alten Laptop HP 6730b lief bisher Ubuntu 16.04 mit einer einwandfreien WLAN-Verbindung. Heute habe ich 18.04 neu installiert ( "/" wurde neu aufgesetzt, "/home" blieb unangetastet) und nun funktioniert das WLAN nicht mehr. Warum auch immer aber die On-Board-Schnittstelle phy0 ist immer "blocked". Daher habe ich WLAN-USB-Adapter als Alternative versucht, aber der funktioniert auch nicht. Hat jemand noch eine Idee? Hier mal die notwendigen Infos (USB-Adapter inklusive):
