How to Know if Someone Is Using Your Wireless

By Neil Edwards

While wireless networks have made home networking more convenient, the technology also carries an important security concern for many users. Many different security options exist to keep unwanted users from connecting to the network, including requiring an access password or providing the router with a list of devices that are approved to connect to it. The settings menu for most routers allows a network administrator to view a list of all of the devices that are connected to the network.
