ich habe schon seit längerem das Problem, dass sich meine Intel WiFi 5300 WLAN-Karte (mini-PCIe) ohne einen nachvollziehbaren Grund deaktiviert und nur noch durch einen Neustart wieder aktiviert werden kann. Irgendwann geht einfach die WLAN-LED aus und ein neuladen der module iwlwifi und iwldvm macht keinen unterschied.
