JumpStart will now begin trying to establish a WPS connection using the PIN. This process can be time-consuming and is not guaranteed to work. If successful, your computer will connect to the network.

is a specialized version of the popular, portable Dumpper wireless network management tool for Windows. It is widely used by network administrators, cybersecurity enthusiasts, and IT students to audit wireless security and analyze local networks.
Dumpper V-40-1 is part of a series of portable freeware tools designed to display and analyze security flaws in local wireless networks. The software operates by scanning localized airwaves for Service Set Identifiers (SSIDs) and Basic Service Set Identifiers (BSSIDs). It maps these out against known default PIN algorithms used by router manufacturers during the height of the WPS deployment era. Dumpper V-40-1
Dumpper V-40-1 is a lightweight, executable application developed for Microsoft Windows environments. It provides a graphical user interface (GUI) to inspect security vulnerabilities in local Wi-Fi architectures. It is particularly known for checking the structural integrity of protocols on home and enterprise routers.
The V-40-1 designation refers to a specific version of this utility. Online searches reveal that earlier versions, like and v40.1 , were among the most widely circulated and discussed in tutorials, particularly those written between 2016 and 2018. Later iterations, such as v50.5 and v91.2, continued the software's evolution, but the V-40-1 version remains a notable landmark in its history.
To use the utility for an authorized security audit, an administrator typically follows a standardised multi-step workflow:
If you want, I can:
The standout feature. It can scan for nearby routers with WPS enabled and attempt to calculate the default PIN based on the BSSID (MAC address) using various known algorithms.
: Resolves exact hardware MAC addresses (Basic Service Set Identifiers) alongside the public broadcast name (Extended Service Set Identifier).
The tool performs a localized scan, organizing access points by their MAC address, signal strength, encryption style, and WPS status.
JumpStart works by trying the possible combinations of the 8-digit PIN. Because of a design flaw in the WPS protocol, the PIN is validated in two halves, which dramatically reduces the number of possible combinations from 100 million to just 11,000. This makes the attack feasible within a matter of hours, or even minutes in some cases. However, it is important to note that this method is only effective against routers with a flawed WPS implementation and, crucially, with WPS still enabled. Many modern routers have either disabled WPS by default or have implemented lockout policies that prevent this kind of attack after several failed attempts. JumpStart will now begin trying to establish a
Because Dumpper is older freeware hosted on third-party forums and legacy repositories, many online download links have been compromised. Malicious actors frequently package these old executables with . Running a legacy .exe from an untrusted source can expose your primary Windows machine to severe system infection. 2. Obsolescence against Modern Routers
: Flags exact host security configurations, identifying networks running Open, WEP, WPA, or WPA2 Personal protocols. 2. WPS Protocol Vulnerability Assessment
It is highly regarded for its portability, meaning it does not require a formal installation process, making it a convenient tool for network professionals who need to perform quick on-site audits. Key Features of Dumpper V-40-1 1. Robust WPS Auditing

This tab acts as an administrative hub for the host machine's previously established connections. It reads and parses stored configuration profiles from the Windows operating system registry. For administrative recovery purposes, it allows users to view saved WPA pre-shared keys (passwords) for any network the machine has legitimately connected to in the past. Operational Workflow
