What Wi-Fi Scanner is

Wi-Fi Scanner is a Windows program for finding nearby wireless networks and inspecting their signal and connection details. It displays network identifiers, signal quality, channel, data rates, security, channel utilization, and clients. It supports 802.11a/b/g/n/ac/ax across 2.4 and 5 GHz bands, with channel widths from 20 to 160 MHz, including 80+80 MHz. Users can graph signal level over time, view signal spectrum masks, and filter networks by quality, mode, security, and other parameters. The software can connect to detected networks, manage wireless profiles, and connect or disconnect wireless adapters. It detects WEP, WPA, and WPA2 security standards and supports WPS 1.0 and 2.0. The maker describes it for home users checking signal distribution or access-point placement and corporate administrators planning or monitoring wireless security.
