NetSpot, The Free Wi-Fi Mapping And Troubleshooting App, Comes To Windows

Windows: Net-spot is an amazing OS X utility for mapping out Wi-Fi networks, finding spots of poor reception, and troubleshooting how to fix them, and now it's available for Windows. Best of all, it's still completely free.

Like the Mac version, Net-spot for Windows lets you see all SSID in your vicinity, their operating channels, which ones are interfering with one another, and more. You can list off all of the networks in your vicinity, and use the tool's mapping feature to lay out where the access points are located relative to your current position. The built-in channel and strength analyser can run in the background, so you can map out reception as you move around your house. Net-spot also builds a live heat-map of your signal strength, so you know where you should position your access points or routers for best reception where you want to work (or where you should put your desk for the best reception.)

The Windows version is missing a few features though, like the ability to create multiple snapshots and zones per survey project, but they're coming soon. Net-spot supports Windows 7, 8, and 10.
