I turn my WiFi on and off at my modem because I don't use it frequently. Of course, it's set up with an SSID, a custom password, and usually it's disabled. Today, when I tried to turn it on I noticed it had lost all the settings. Plus, when I tried to turn it on after reapplying the settings I could no longer turn it on and the settings would go back to default. I had to do a factory reset in order to get it to work again. Does this happen if my ISP updates the firmware? Does it indicate someone managed to get into my modem? Never had my WiFi settings lost and unable to restore.
