Hallo Zusammen,
ich habe das Problem, dass sich mein Laptop nach dem Aufwecken nicht mehr mit dem WLAN verbindet. Es werden auch nicht die möglichen Router in Reichweite angezeigt. Durch die SuFu bin ich auf folgendes Thread gestoßen: https://forum.ubuntuusers.de/topic/nach-16-10-installation-kein-internet-mehr-nac/2/#post-8652643
Allerdings wird da das Problem durch 16.10 impliziert und ich habe noch 16.04 LTS
