Thanks Midas for pointing that out and to whomever GBR is.
Where did I do that?
On a related note, SZ Development also makes available recently updated 'winpcap' dependent (and thus not natively portable) York network logger (https://thesz.diecru.eu/content/york.php), among many other free utilities.
I suggest the current topic be turned into an umbrella topic for all SZ utilities -- as already done for Nirsoft and Skwire.
With Homedale you can search for Wi-Fi / WLAN Access Points and monitor their signal strength. See an overview of all available access points with their signal strength, encryption [WEP/WPA/WPA2], speed and channel. You can also monitor the signal strength of selected access points in a graph over the time. With a right mouse click, you can start logging to a text file, create a screenshot, or connect/disconnect from a Wi-Fi / WLAN access point.
Additionally, you can use the detected access points with Google Geolocation and Mozilla Location Service in addition or separate from a GPS tool if present.
Footnote for the curious: Background story behind this release
When Homedale starts, it downloads OUI.txt (file containing network devices vendors names mapped to MAC addresses).
Prior to this new 1.65 release, the OUI.txt file was downloaded from the official server, but this server is pretty slow, and takes over a minute to download the file. (3MB+)
When closing Homedale during this download, the process would keep running in the background until it had completed the download.
This elucidates the slightly perplexing situation where Windows Task Manager would still display an active Homedale process, even after the Homedale application had been terminated.
Homedale's developer swiftly produced an updated version calling a fleeter OUI.txt server (download now takes about 15 secs), and all's well that ends well...
