This act of tapping into someone else’s wireless internet connection without their permission is both outlawed and morally wrong. Nevertheless, many individuals try to connect to different people’s Wi-Fi networks for a number of reasons, including curiosity, or for their own needs, or even with the intention of harming others. This is achieved through the use of software tools that have the capability to decipher the key used by a network to secure its communication. With some precautions, wireless internet connections can be very well protected and the bad news is that the average computer user is not even aware of the existence of most of these protection measures. To ensure that your Wi-Fi network cannot be hacked, you need to ensure that you have a strong password that you use on the wireless router and this must be a combination of uppercase letters, numbers and symbols. Further, utilize the cutting edge encryption type supported by your router such as WPA2. Do not use the out-dated methods such as the Wired Equivalent Protocol which is easily penetrable. Another good practice is to anonymise your wireless network name (called SSID broadcast in this context). This make the network slightly harder to recognize by hackers. Last but not the least, it is recommended that you check the firmware version of your router and where necessary, use the newest firmware since it is usually equipped with the most recent security fixes. If these basic measures are followed then it will reduce the probability of someone evil getting the desired wireless internet access.
