RECENT UPDATE: September 2015, NetSpot 2.4.623 released. We keep polishing the product while something really new is getting ready to be revealed. Meanwhile the new build is addressing a few visual and internal issues and acknowledges smoother loading of large map files. Scroll down for more details.

Previous updates:

June 2015, yet another minor update posted for NetSpot 2.4. The build #2.4.607 adds several requested features and improves overall app efficiency. We also did some preliminary improvements for the upcoming OS X El Capitan 10.11, more to come.

March 2, 2015, NetSpot 2.4.590 is released.

Today, February 9, 2015, we release NetSpot 2.4.585. It’s also a minor release that addresses a few issues reported by our users, and adds a few polishing touches here and there. See the changelog below for details.

You’ll be pleased to know that our bigger, better, stronger NetSpot 2.4 is available today as a free update for all users. It has ten+ new features, as well as numerous improvements and bug fixes. This update also adds full and improved support for OS X 10.10 Yosemite.

NetSpot 2,4 introduces Global Preferences

First, we’re excited to tell you that NetSpot now has Global Preferences, accessed from the main menu bar (NetSpot > Preferences). This gives you one convenient spot to adjust NetSpot’s settings, and adds a bunch of new options — including a brand-new way to manage AP aliases. There are six sections (note that some features are for PRO users only):

  • Discover Mode: Adjust the WiFi scanning interval, when the app should clear inactive networks and when it should erase old data.
  • Survey Mode: Adjust how often projects are auto-saved [ PRO version required], the number of measurements in a sample, the sample point indicator type, and whether or not to show heatmap colors between the data sample areas (green circles).
  • Heatmap: Adjust the AP detection proximity and heatmap gradient colors, as well as the settings for each individual heatmap. This section also has a handy button for resetting all the heatmaps back to their default levels.
  • Troubleshooting  PRO : Set the critical and acceptable levels for each Troubleshooting visualization, or reset them all to default levels.
  • Aliases  PRO : Add or remove network AP aliases (which will be shown in both Discover and Survey modes) and import or export a list of aliases in CSV format.
  • Active Scanning  PRO : Choose to conduct speed tests via HTTP using hosted PHP scripts, as well as the option to add an iperf3 server address for active scanning via TCP and/or UDP.

We’ve also added a bunch of new features to Discover Mode. The right-click menu is now available when clicking on any column (instead of just the first one), and it now includes an option to set a custom color for each network. The right-click menu offers more selection options as well, including Invert Selection, Select All Filtered, and Select Networks by Channel.

Two other often-requested new features are the ability to add a heatmap legend when exporting heatmaps as images and the ability to skip all further tests if an error occurs during Active Scanning.

We’ve also squashed several annoying bugs, including the excessive memory consumption that was occurring with the following visualizations: Quantity of APs, PHY Mode Coverage, and Frequency Band Coverage, as well as errors that occurred when exporting or clearing data in Discover Mode.
