See Every Device on Your Wi-Fi
You are standing in an office that is not yours, asked to find the NAS. Nobody present knows the router's admin password, and the sticker on the underside has worn off. The Wi-Fi password, however, you do have. That is enough. A device on the subnet answers ordinary local queries. Those answers are enough to list what is there. Dotori WiFi Scanner works from that position. No admin page required…
In an unfamiliar office, the task was to locate a Network Attached Storage (NAS) device. The office's Wi-Fi password was known, which proved sufficient for the job. The Dotori WiFi Scanner app was used to identify devices connected to the same subnet and gateway. The app does not require admin login or any account to operate. There are three scan modes available: Fast, Balanced, and Accurate, with each offering varying levels of thoroughness.
The results display the category of each device, such as access point, computer, mobile device, TV, NAS, printer, CCTV, or PLC candidate. The app uses various clues to determine the device type, combining responses from TCP ports, mDNS, SSDP, WSD, NetBIOS, the manufacturer's OUI (Original Equipment Manufacturer identifier), hostname, and service hints.
Users can copy the results into a CSV file, and clicking on open web ports (80, 443, 8080, 8000) opens the device's corresponding web interface. No credentials are stored or requested by the app. SSH sessions are initiated directly from the app, with the host and port provided for the SSH terminal. The absence of a device on the scan results does not necessarily mean it is not connected to the network; client isolation, VLANs, and firewalls can hide devices.
Industrial equipment, such as PLC candidates, requires explicit approval before running detailed identification scans to prevent probing industrial networks without authorization. The scanner processes all data on the device itself and does not upload any results to external servers. Users should only run the app on networks they own or have explicit authorization to manage.
Scanning a home Wi-Fi network using this method usually reveals devices that were previously unknown.
