As the saying goes, "the devil is a foot high", some people want to think about not spending money to rub your net, causing your network greatly reduced, this kind of beggar-thy-neighbour thing, we spend the money of the people, can promise? How to prevent others from cracking effectively. I would say a few ways:
1, when you feel the speed significantly slower, suspected that someone rubbed the net, the login router service address, in the "Wireless parameters----Host State", will show that there are several hosts to connect your router, if you are a computer, but show there are 2 or more hosts, then, you have been rubbed!!
2, the use of "WPA--PSK/WPA2--PSK" security type, encryption method to select "AES", the password as far as possible to set up a complex, such as "Use your email address", he even has cracked the password software, but also very difficult to crack. This is suitable for dealing with the general crack thief.
3, enable the "MAC address filtering" function, turn on the "Security Settings---MAC address filter", your host network card and mobile WiFi MAC address "Add to the new entry", so that he cracked your password, will be blocked by MAC address filtering, that is, the firewall blocked by the router, Unable to access. Host network card MAC address to find a little trouble, if it is "Windows" system, in the "Start---run" box input "CMD", enter the command line mode, and then enter "Ipconfig/all", in the bounce out of a lot of information, The number of two digits or letters in the back of the physical address is your network card MAC address. The Android phone, click on the WLAN, click on the menu button, pop-up a small box "advanced", after the point, you will see your phone's "Mac."
4, if for someone directly to crack your login router password to crack your wireless routing, then in the "System Tools----Modify Login password", your login account and password for a high level of security changes, login password can be the letter symbol, and the number of digits can reach more than 13, see how he cracked!
5, if still feel insecure, and finally teach everyone a trick! Let him not even see your wireless signal.
On the wireless Parameters-Basic Settings page, will be "Allow SSID broadcast" Check out, this is your mobile phone networking, you will find that the wireless signal is not found at all, this is the right, we just want to let him see also can not see, so fundamentally eliminate rub net, haha. To connect, if it is a mobile phone, "Add network Connection", directly enter their SSID number, and security password, you can successfully login!!
