Wi-Fi, the short name for wireless high-fidelity Internet access, is a method of connecting to the Internet using radio waves rather than cables, making computer use more convenient than never, because the user is no longer limited to the limits of his own private space. Now a wireless computer user can access their own or their employer's wireless network, but they can also access their neighbor's. With the increased availability of wireless computer networks, a new ethical dilemma arises. Just because you can access someone else's computer network, known as piggybacking, whacking, joyriding, war-chalking, air-hopping, or war-drive, does that mean that Is it ethical to do so? While many people believe that exploiting someone else's computer network is ethical. Someone else's wireless network is a harmless activity and has no downside for the owner of the wireless network, in reality there are indeed negative consequences and therefore the practice cannot be considered ethical. Courts have determined that wandering onto another's wireless network constitutes intrusion against the owner's router because this action could cause damage by slowing down network speeds and/or introducing viruses into that network. . The person who accesses someone else's Wi-Fi network also harms the Internet service provider. These companies are in the business of selling Internet access. Using someone else's account without their permission deprives businesses of their rightful profit. There is also potential harm if someone does not secure their Wi-Fi network. It allows unauthorized access and, in some cases, allows firewalls and filters that have been established to bypass and ignore safety and security, especially for minors.
