So ich habe mir jetzt das Notebook von meinem Bekannten nochmals geholt. Habe jetzt die dort genannten Modulparameter gesetzt (gelb), die praseodym empfohlen hat. Verfügbare WLANs werden
weiterhin nicht angezeigt. So wie eingangs von tomtomtom empfohlen die entsprechenden Infos zur WLAN-Karte etc:
Hier erstmal alle Infos, die vielleicht noch wichtig sein könnten:
