    Default How to block WI-FI permanently

    My cousin runs a wi-fi cyba café near a college. Business has been good until the students decoded his wifi password. It started with a few students using the WI-FI free of charge, but now almost every student knows the password. He has tried changing the password several times to no avail. How can we permanently block the WI-FI?

    thanks @Rishabh25, he runs the cyba alone. and even though he has tried to keep the password as secret as possible. he has tried adding characters as $%#&*; they still find a way to crack it. does anybody know how to block, there has to be a way; otherwise he will close the business down. somebody please help.

    this is rather serious. some dangerous elements could also take advantage of the situation. admin should know more about how to solve this problem. tagging @admin here.

    if ur passaord is WPA/WPA2 thn hacking it is difficult as compared to others ones(WpE etc.).. Specially when %#* etc are used as password...

    hopefully someone else would come up with a solution i am totaly blank...

    Blocking other people from using your wifi needs a lot of time and effort. You can block them by tweaking in your router's settings. As I said, it will take a lot of time because you will block each IP address that will use your wifi. If you have a lot of time, you can try what I said, but if you don't have that much time, you can just change your password into a strong one.

    wifi password can be found easily if i use ur device on which you are using wifi either on mobile or pc.
    on mobile from store download file explorer and install it i am not writing further procedure u can google it.
    similarly from network and sharing center in control pannel we found wifi password on pc,, only condition wifi is to be working on that pc.
    may be more ways for finding password i dont know.
    only thing you have to remind is dont use your personal device to other on which wifi is working. and also install cleaner on your pc before leaving your pc run cleaner so that your history,cookies,stored passwords can be removed.

    You can make your WiFi signals "invisible" to devices. For the devices that you intend to use with this particular WiFi, you could pair this in advance before turning on this feature in the WiFi router/modem!

    Even though I am not an expert on how to solve this issue, I came across a network monitoring application called ""Fing". Just connect your WiFi network and download the application. Then open the application, tap the refresh button and you can see all the devices connected to your network with an indicator to show you whether it is a PC or a smartphone. You can communicate with these devices through various options and even disconnect them. There is also an option to ban them forever.

    Thank you for this information nevinjohn. I didn't know you can turn your wifi's signal into invisible. I only knew you can block IP addresses through router settings. Can I ask, how do we do the pairing of wifi? Do we get other's IP address to pair?

    This feature is by default in all routers. You can turn it off. See below screen shot





    Search for the SSID option, and disable it. No other devices can now see your WiFi signals, except for the ones who are already connected / known the router. Thats what I meant by pairing. See the explanation in the screen shot itself!

    Cheers!
    Nevin.

    Try to tweak your device. There are a lot of resources from Google. You can change your wifi password or you can use applications to kill the wifi connection of those devices who are connected to your network.
