    I've had this problem with my Galaxy S4 since about last November now, where I lose all new wifi networks that I connect to after I turn wifi off (whether it is to save battery, airplane mode, phone reboot).
    And each time I turn on my wifi again, I have to re enter the password for several networks that I have started using after the problem started.
    I have tried to delete older networks that I do not use anymore, but that did not help.
    Furthermore, my wifi antenna was replaced 2-3 before the problem started.
    Does anyone know what could cause this and how to fix it?

    Thanks for you help!
