If you have a wireless Internet connection through a router, it is likely that you have not changed the network key that your phone company provides you default. Many people, both at home and in the office, do not bother to change the WPA key because they do not care or do not know how to do it.
However, this is one of the safety hazards posed by wireless or WLAN networks. Nowadays there are programs that allow you to decrypt the keys that your Wifi provider generates by default. In this article we will show you why this happens and how you can change your network key.
How can someone find out my router key?
You know that Wi-Fi networks allow you to connect to the Internet without cables. That represents a security risk, so carry a system of encryption and authentication , which in the most common cases is WPA (WiFi Protected Access), but can also be (older) or WPA2 WEP. The main danger is that people in your environment rob you of bandwidth if they can overcome the security system.
Whether you use ONO or Telefonica, Jazztel or other companies, telephone companies use a system to generate their passwords very simple, so it is easy to discover them with the right program, only knowing public data: the BSSID (the 4 digits that appear next to ORANGE_XXXX) and mac router (a number of 12 digits), which can be determined for example with programs such as NetStumbler .
Then the person in question introduces this data into a software that does the same operation as the key generators of the company and get your network key to connect to your Internet connection without paying anything and even can damage your computer and network If it brings bad intentions.
