What it is
Wi-Fi Scanner is a Windows utility for finding nearby wireless networks and examining their radio and connection details. It displays SSID, RSSI, BSSID, signal quality, channel, data rates, security, channel utilization, and clients. Support covers 802.11a/b/g/n/ac/ax, 2.4 and 5 GHz bands, and channel widths from 20 to 160 MHz, including 80+80 MHz. Users can graph signal levels over time, view spectrum masks, and filter networks by quality, mode, or security. The software connects to detected networks, manages wireless profiles, and connects or disconnects adapters. It detects WEP, WPA, and WPA2 and supports WPS 1.0 and 2.0. Version 25.05, released May 16, 2025, lists initial Wi-Fi 7 support. A Wi-Fi adapter, administrator privileges, and internet access are minimum requirements.
