NetSurveyor

A Wi-Fi network-discovery and site-survey tool. Where Network Discovery gives you a quick live list, NetSurveyor tracks the networks around you over time and shows the same data four complementary ways.

Use it to read a neighbourhood quickly, to see where the congestion is, and — by carrying the Wireless Toolbox through a space — to find coverage and dead spots.

You need nothing but a phone or computer with a browser. There is no app to install.

Getting started

Open NetSurveyor from the menu. Use Start / Stop (top-right) to run or pause the scan. While a scan is running, the Wi-Fi symbol in the title bar lights up arc by arc.

Left panel

  • 2.4 GHz / 5 GHz — choose the band the charts show.
  • Access-point list — every access point with its SSID (name), BSSID (address), signal in dBm, channel and security. Tap a row to hide or show that access point in the charts.
  • Select all / Deselect all — show or hide every access point at once.
  • Show hidden / Hide hidden — include or leave out networks that broadcast no name.

The four views

TabWhat it shows
Site SurveyTwo charts. On top, each access point drawn as a signal “mountain” over its channel (beacon strength per access point). Below, Occupied Channels — a running count of beacons detected on each channel.
Channel OccupancyEvery access point as a bar, grouped by channel — where the congestion is.
AP TimecoursesOne small chart per access point: its signal over time. This is the view to watch while you carry the Wireless Toolbox through a space to find coverage and dead spots.
WiFi NetworksAccess points grouped by network name, strongest first — so a network served by several access points or radios reads as one group. This view always shows both bands.
Signal is measured at the Wireless Toolbox, by its measurement adapter — not by the phone or computer you are reading this on. To survey a site, move the Wireless Toolbox.

Surveying a site

  1. Put the Wireless Toolbox at the first position and press Start.
  2. Let it scan a few times, so the view settles.
  3. In the access-point list, leave selected only the access points that matter to you.
  4. Move the Wireless Toolbox — not just the phone or computer showing the page — to the next position.
  5. Watch AP Timecourses: each access point's line rises and falls as you move, showing where its coverage is strong and where it fades.

Signal strength says how strongly the Wireless Toolbox receives an access point’s signal. It is not a measure of speed; for that, use Channel Performance or Floor Plan Survey.

NetSurveyor or Network Discovery?

Network Discovery is the quick live list. NetSurveyor adds history, per-channel occupancy and grouping by network name.

  • Save as PDF — see below. Each of the four views becomes its own page.
  • About — version information.

The ☰ button (top-left) returns to the Wireless Toolbox menu.

Save as PDF

The ⋮ menu (top-right) has Save as PDF. It captures the tool exactly as shown — one page per view — and writes one file to your device’s Downloads folder, named with the tool and a timestamp, e.g. NetSurveyor 2026-08-13 14.32.05.pdf. Every save is timestamped, so nothing is overwritten.
