The router or “wifi modem” is that small computer that provides Internet access at home, and when it does not have a secure internal configuration, it can not only allow neighbors to steal the Internet, but even hackers They can take control of the network and the computers or devices at home. Yes that includes that they can hack your PC, cell phone and other devices in your house remotely from the other side of the world.

A weak or insecure configuration can not only allow neighbors and strangers to discover the Wi-Fi key to steal the internet, but they can even obtain the access key to the settings of the router or modem itself to get full control over that network. There are programs and applications like Router Keygen (which has an Android version) or Reaver that allow you to do this without having to be an expert on this topic.

RouterCheck tries to enter the router using the most common default passwords and the most used by people to test this aspect. If you get a blue color here, it is understood that the application could not enter, so the password is relatively strong.

Another problem that RouterCheck detects is if the option WPS is activated in the router or modem (something that is activated by the factory in most of these computers) and suggests deactivating it because this option, specifically the WPS PIN, it is vulnerable to brute force attacks that are used to easily obtain the router key with programs such as Reaver.
