    It is superb! It works on my laptop wifi which had been become “unmanaged” since I have turned it as a hotspot access point and I forgot how did I do that. Thanks alot!!!!

    Unbelievable. This is great. Is this a bug? Maybe someone should tell them so this could be fixed. I can’t see a situation where this would benefit someone, except maybe as a security feature.
