Wifi WPS Plus

Wifi WPS Plus: Network Security Scanner & Connectivity Tool

Wifi WPS Plus is a specialized Android utility that scans for Wi-Fi networks to assess the security of their Wi-Fi Protected Setup (WPS) protocol. Users deploy Wifi WPS Plus to identify routers using vulnerable, easily guessed PINs, helping them secure their own networks against unauthorized access. The app also provides a legitimate method to reconnect to previously authorized networks if a password is forgotten, utilizing the device’s saved credentials. For network administrators and security-conscious users, Wifi WPS Plus serves as a practical diagnostic tool to audit local wireless security.

Network Scanning and WPS PIN Detection

To begin, users open Wifi WPS Plus and initiate a scan. The app searches for available Wi-Fi networks and identifies those with WPS enabled. For each detected network, Wifi WPS Plus attempts to retrieve the router’s default WPS PIN using several non-intrusive methods. This process does not involve connecting to the network but gathers information broadcast by the router itself. The primary action is analyzing the network’s beacon frames to determine its WPS status and potential vulnerability, providing a security report for the user.

Router Model Identification and Default Key Database

Wifi WPS Plus includes a database containing common router models and their manufacturer-set default WPS PINs. The app cross-references the scanned network’s details, such as the BSSID (MAC address) and SSID, against this internal database. If a match is found, Wifi WPS Plus displays the likely default PIN for that specific router model. Users can then consult their router’s manual or label to verify this PIN, helping them understand if their network relies on a widely known, insecure default credential.

Calculating PINs Based on Router Algorithms

For certain router brands, Wifi WPS Plus can calculate potential WPS PINs using known algorithms. The app uses the router’s MAC address, which is publicly broadcast, as a seed for these calculations. Users see the app process this data to generate a shortlist of probable PINs. This function demonstrates a specific cryptographic weakness in the WPS implementation of some hardware, showing how a static identifier can lead to predictable passwords. The result is a practical demonstration of a theoretical vulnerability for educational purposes.

Connection Testing with Recovered PINs

If a user has lost access to their own Wi-Fi network and the WPS PIN is available, Wifi WPS Plus can facilitate a reconnection. The app provides an interface to input a known PIN—either from a router label or discovered through its scanning features—and initiates the WPS connection handshake. The user’s device communicates directly with the router to establish a connection using the PIN instead of the standard password. This is a legitimate use of the WPS protocol to regain network access without the full pre-shared key.

Security Assessment and Vulnerability Reporting

The core function of Wifi WPS Plus is to output a security assessment for the user’s network. After scanning, the app clearly indicates whether the detected network uses a strong, unique PIN or one that is common and vulnerable. This report allows a user to proactively strengthen their router’s security by disabling WPS or changing to a more secure setup if a vulnerability is found. The workflow ends with the user informed and empowered to take action, which is the primary goal of the Wifi WPS Plus application.

Managing Location Permissions for Scanning

Due to Android OS restrictions, Wifi WPS Plus requires location permissions to perform Wi-Fi scanning. Upon first launch, the app guides the user through the necessary steps to grant these permissions in the device settings. This is a mandatory system requirement for any app that scans for networks on Android versions 6.0 and above. Users must enable this permission for the scanning features of Wifi WPS Plus to function correctly, ensuring the app operates within the boundaries set by the operating system.
