If you run a Wi-Fi network at home or at the office, it is important to know who is connected to it. At worst, unauthorized users may be able to hack into computers on the network and gain access to sensitive information; on the less-dangerous end of the spectrum, a surplus of users can slow down the network speed, particularly if they are streaming video or downloading files. By tracking connected devices, you can keep your network safe and make it easier to troubleshoot performance issues. Writer Bio
