Hey Leute,
bin vor einigen Tagen auf Ubuntu umgestiegen und habe leider heftige Probleme mit meinem Lan denn die Verbindung bricht immer wieder ab (bzw wird seeeehr langsam). Ich hatte schon recherchiert und bin auf den mittlerweile wohl veralteten Tipp gestoßen dnsmasq zu installieren. Das hat leider nicht geholfen, allerdings "resettet" der restart von dnsmasq wieder und ich habe für einige Minuten eine voll funktionsfähige Verbindung bis o.g. Problem auftritt. Mit meinem (noch) Windows Laptop und Smartphone treten keine Probleme auf.
