Hilfe Nach Neuintllation von Xubuntu 16.04 LTS kein WLAN

[Lutz Müller]

Hi zusammen, hi Frank,

ich hab das gleiche Problem. Erst dachte ich das update wäre 
verschossen, dann nach Neuinstallation genau das gleiche Problem. und 
das mit zwei verschiedenen USB Sticks.

Hab schon im Netz gesucht, aber keine brauchbare Hilfe gefunden. Muss 
gerade auf Windows arbeiten, da ich hier kein LAN habe. Ich hänge mal 
meine Syslog an, mehr Daten kann ich holen, wenn ich neu boote.
