  1. Hello Mukesh,
    Thank you for the info. I have a question, my android phone suddenly stopped connecting to my wifi, but when i use a analyzer app it shows my device as being connected to a hidden network that i can not find a way to disconnect from. When i try to connect to my wifi i get the auth error.
    My neighbor hates me and ive had many connection issues since his moving in 8 months ago, before this my internet worked flawlessly. Could he have hacked my device? How can i disconnect from this hidden ssid, and is this connection to the hidden ssid why i cant connect to my network?
    Any help would be most appreciated
