Download Dumpper – WiFi Network Scanner and Manager for Windows

Dumpper is a free Windows utility for scanning, analyzing, and managing WiFi networks in your vicinity. It displays detailed information about detected wireless access points including SSID, BSSID (MAC address), channel, signal strength, encryption type, and network vendor, making it useful for network diagnostics and wireless site surveys.

One of Dumpper’s notable features is its WPS (Wi-Fi Protected Setup) pin analysis functionality, which can check whether nearby networks have WPS enabled and display PIN-related information — a feature primarily used by network security researchers and IT professionals to audit their own network configurations for WPS vulnerabilities.

Dumpper is lightweight, portable, and requires no installation. It is commonly used alongside Jumpstart for WPS-based connection testing on authorized networks. The tool is intended for use on networks you own or have explicit permission to test, and is a valuable addition to a network administrator’s toolkit for wireless assessment and troubleshooting.

Key Features

• WiFi network scanning – Detect and list all nearby wireless networks with SSID, BSSID, channel, signal strength, and encryption details.
• WPS pin analysis – Display WPS information for networks with WPS enabled for security auditing on authorized networks.
• Vendor identification – Identify router manufacturers from BSSID MAC addresses for network profiling.
• Signal strength monitoring – Real-time signal level display for assessing coverage and interference.
