Hi all, I use the ADSL technology for having the Internet. For that, I have a wireless N ADSL2+ modem router model TD-W8151N that I connect it wirelessly by my laptop and smartphone and etc. I've heard that there is some Windows or smartphone app that can crack my modem and uses my traffic! My traffic volume finishes very soon. My modem configuration is as normal and is fine but I don't know what is that method those crackers use to break the security of it and my traffic is being stolen still! Is there any way to block the way crackers crack my modem? If yes, how please?
