Hallo Leute, habe hier ein Problem.
Ich hatte Win7 (meines Dual-Boot-Systems mit Ubuntu Studio), am Samstag auf Win10 upgegradet.
Seitdem, bekomme ich keine Netzwerkverbindung mehr zu Stande, unter Ubuntu. Mit Win10, funktioniert es einwandfrei.
Ursprünglich, hatte ich Ubuntu Studio 16.04 drauf, was mit Win7 einwandfrei im Netzwerk funktionierte. Mittlerweile bin ich auf Ubuntu Studio 18.04 gegangen, was meine Probleme aber nicht behob. Dabei habe ich aber nur die Root-Partition upgedatet, das Home-Verzeichnis blieb.
Router ist eine Vodafone easybox 804. DHCP ist an, mit manueller IP-Vergabe, an ausgewählte MAC-Adressen.
Wenn ich den Router pinge, kommt keine Antwort. Wenn ich den PC vom Router aus pinge (Diagnose-Tool des Routers), kommt ebenfalls keine Antwort.
Hier meine Ausgaben:
