Hallo,
ich habe folgendes Problem und bin nicht sicher, woran es liegen könnte. Nach einer Weile schaltet sich das W-Lan auf meinem Lenovo Ideapad (Ubunto 16.04.4 LTS) immer wieder ab. Der Abbruch der W-Lan Verbindung erfolgt in unregelmäßigen Abständen. Sobald ich die W-Lan Verbindung softwareseitig in dem Einstellungsmenü neu starte geht es wieder. Irgendwelche Ideen, woran es liegen könnte. Welche Daten benötigt ihr für eine Diagnose? Vielen Dank im Voraus.
Hier einige Ausgabedaten, die womöglich hilfreich sein könnten:
