V5.0 build 1003 21/May/2024

  • Fixed issue where channel width displayed 80Mhz instead of 160Mhz
  • Fixed missing icon for uninstall and add/remove/installed apps program listing

V5.0 build 1002 17/July/2020

  • Added channel width, dropouts, vendor and max RSSI to summary log
  • Fixed an issue when loading some WirelessMon project files where the map would not initially be redrawn correctly after loading
  • Fixed a bug in the 64bit build of WirelessMon where the signal strength of an AP when using the hexagon mapping function did not update correctly and all samples were the same

V5.0 build 1001 28/May/2020

  • Spectrum analyser graphs, changed to better represent the signal spectrum in use by an access point including channel widths.
  • Added missing 5ghz channel 144 to graphs.
  • Changed congestion graph on summary tab to take channel widths into account.
  • Export to CSV, added channel width to exported information.
  • Changed "Supported Rates" summary column to "Max Rate Supported" and only displays the highest rate the AP is capable of.

V5.0 build 1000 19/May/2020

  • Added new contour mapping function that predicts the signal strength around the sample point based on signal strength. This new method can also predict signal strength losses based on obstructions on the map when a suitable map and a base station location is used.
  • Added new spectrum analyser graphs to see channel use and their overlap of other channels.
  • Changed how the access point list is maintained so that logging, list updates, drawing and sorting are much faster.
  • Added new Auto logging option in general options and /ALOG command line parameter to start logging when starting WirelessMon.
  • General options, added auto calibrate options for min/mix signal settings.
  • Added ability to apply a filter to the summary list of access points, currently to display unsecure access points only.
  • Added "Check for new version" function.
  • Fixed SSID Unicode characters not being converted properly.
  • Removed standard/professional edition. Registered version is now equivalent to professional edition.

V4.0 build 1009 19/March/2015

  • Added support to display when a network is 802.11AC
  • Increased size of "Select AP" dialog window so maximum SSID names and MAC address can be displayed without the need for scrolling/resizing the window
  • Decreased memory use when saving a signal strength image to try and prevent out of memory errors when working with very large maps
  • Fixed a display/synchronisation issue with the access point list occasionally assigning the wrong status icon to an entry if rapidly sorting the list
  • Improved information element processing when scanning for networks to improve extra information reported (such as 802.11N speeds)
  • Corrected a typo of "Lattitude" instead of "Latitude"
  • Added an error message when no network cards are detected

V4.0 build 1008 26/June/2013

  • Added support for the newest version of the MetaGeek Wi-Spy DBx
  • Added support for connecting to hidden networks when SSID is known
  • Added support for sending security passphrase from WirelessMon during the connection process in Vista/7/8 rather than requiring windows to display the key entry dialog in the system tray.
  • Fixed a bug that was preventing connection to access points when specifying a MAC address
  • Changed behaviour where if an access point was set to use WEP/WEP64 WirelessMon was displaying WEP-104/WEP128. This is due to observed behaviour in Windows Vista/7 that only WEP (key of any length length) is reported by Windows (not WEP-40 or WEP-104) no matter what WEP setting is used in the router. Now WirelessMon will only display "WEP" unless extra information is available.

V4.0 build 1007 30/July/2012

  • Added delimiting characters to the SSID field when exporting the access point summary list to CSV to prevent SSIDs with ',' characters breaking the format
  • Fixed a bug where the "Other" tooltip count for the channel use was incorrect
  • Fixed a bug where the sorting of the list view was affecting the output of the access point log
  • Fixed a bug where removing SSIDs from the SSID filter list would not be applied until Wirelessmon was restarted
  • Fixed a bug where a dropout could be logged incorrectly each sample
  • Fixed a bug where sometimes some sample areas would not be filled in during interpolation
  • Fixed a bug where KML files were being output in double byte format
  • Fixed a bug where the KML version of the connected node log was outputting the GPS co-ordinates in the wrong location
  • Fixed a case where the GPX version of the connected node log could be created without the correct header

V4.0 build 1005 6/July/2011

  • Fixed a bug with the project file save where some fields (security, latitude, longitude) were not being saved correctly

V4.0 build 1004 6/June/2011

  • Some changes were made to the installer to prevent "Cannot save to configuration file" error in some instances
  • Renamed "Strongest RSSI" column to "Max RSSI" to save some screen space

  • Fixed a crash in the connected node log when using GPX format

V4.0 build 1000 7/March/2011

  • Added USB support for Garmin GPS
  • Added some extra error messages if WirelessMon cannot load a map image due to memory limitations
  • Added Import and export functions for MAC address when choosing access points to display on Map tab
  • Added right to left signal strength graph style on summary tab
  • Added "dropouts" count and column to summary view, tracks how often an access points is seen in one sample and lost in the next
  • Added KML (Google maps) log format options to access point and connected node logs
  • Added GPX format to connected node logs
  • Added "Export List" option to right click menu options on summary tab list, will open a dialog that allows the detected access points to be exported to CSV or Google Maps (KML) format
  • Added "Strongest RSSI, Latitude and Longitude" columns to summary view. Latitude and longitude are available when a GPS is configured and records the GPS position of the strongest RSSI value
  • Added an option to manually enter the GPS locations for two arbitrary points on the map during GPS calibration
  • Moved current GPS location to bottom status bar
  • Added auto save project file to log options
  • Added encryption types (WEP-40/WEP-104, TKIP, AES) where applicable for security column. In XP due to WirelessMon using passive scanning, this will only be available when the required information is captured by the network card.

  • Added some extra checking when loading the GDI+ library to prevent failure on some Vista and Win7 machines.
  • Network statistic counters should now be loaded correctly in non-English versions of Windows
