Most modern computers support the wireless network. In other words, they can connect to the internet (and other devices that support wireless) without a network cable. The main advantage of wireless networking – the ability to work with the Internet anywhere in your home or office (if the distance between the computer and the wireless access to the network).

However, if no steps are taken to ensure the security of the wireless network, the following potentially hazardous situations:

- hacker can intercept transmitted or received by you data;
- a hacker can gain access to your wireless network;
- your point of access to the Internet can be captured by another person.

Consequently, if your wireless network is not secure, a hacker can intercept transmitted data on it to gain access to your network and files on your computer and access the Internet using your connection. The latter is very significant: not only is that an attacker takes your data channel and slows down your internet connection, it also absorbs the traffic that you have paid for and which may be limited by the terms of the provider.
