Andrew Calcutt

Andrew Calcutt is a solo developer whose public footprint is anchored in a single, long-evolving Windows utility: Vistumbler. Written in AutoIT and originally released for Vista—hence the name—the program has grown into a lightweight yet surprisingly capable wireless survey tool that still runs happily on Windows 7 through 10. In practice it behaves like a portable spectrum stethoscope: launch the EXE, watch the nearby 802.11 landscape populate in real time, and log every MAC, channel, cipher, and dBm fluctuation to a compact Access-compatible MDB file. Wardrivers use it to build heat-maps of suburban coverage; small-business admins pair it with GPS to document rogue APs; and home owners simply want a second opinion on why the upstairs bedroom stream keeps buffering. The interface is utilitarian—rows of pale-blue grid data and a modest graph—but behind the austerity lies a steady release cadence that keeps chipset tables, WPA3 flags, and NDIS API quirks up to date. Because the binary is self-contained, it drops cleanly onto a technician’s thumb-drive beside inSSIDer, NetStumbler, or Acrylic and complements broader network-audit workflows without demanding installation rights. Andrew Calcutt’s Vistumbler is available for free on get.nero.com, where downloads are sourced from the official Git repository and delivered through trusted Windows package channels such as winget, ensuring the newest build is always fetched and allowing multiple utilities to be installed in one batch operation.
