Moin,

nach einer kompletten Neuinstallation von 16.04 steht mir leider mein herkömmliches W-Lan nicht zur Verfügung. Es funktioniert lediglich über "Telekom_Fon" (HotSpot). Ich würde das gerne wieder auf die herkömmliche Art und Weise nutzen wollen und bitte freundlichst um Hilfe... Leider ist es mir auch nicht möglich, über "Neues Funknetzwerk erstellen..." bzw. "Mit einem verborgenen Funknetzwerk verbinden..." eine Verbindung dauerhaft zu speichern. Eingegebene Daten werden nicht gespeichert - temporär eingegeben, wird keine Verbindung aufgebaut.

Der Treiber ath9k ist da, offenbar eine Atheros-Karte?

Die Ländereinstellungen stimmen nicht (14 Kanäle), teste auch das Deaktivieren der Hardwareverschlüsselung:

sudo sed -i "s/REGDOMAIN=/REGDOMAIN=DE/g" /etc/default/crda 
echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

Neustart

Moin,

sudo sed -i "s/REGDOMAIN=/REGDOMAIN=DE/g" /etc/default/crda echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

Neustart

Das hat funktioniert!

Super und Danke praseodym für diesen weiterführenden Tipp. Sollte ich ergänzend noch weitere Änderungen vornehmen?

Wie gesagt: gemischt WPA/WPA2 (TKIP/CCMP) sorgt manchmal für Probleme. Der Netzwerkmanager soll ja in 16.04 deutlich verbessert worden sein, vielleicht klappts ja auch damit, wenn es auch aus Sicherheitsgründen fragwürdig ist. WPA basiert auf WEP und ist in Minuten geknackt!
