APHound v1.4 Released

APHound v1.4 is now available.

The main changes for this release were to add support for 5GHz access points and to add support for 802.11ac.

New Features

  • Added support for 5GHz access points to the Plus Edition.
  • Added support for 802.11ac to the Plus Edition.


  • Replaced chart legends with colour coding on the access point list.
  • Save and restore the splitter bar position when the application exits and starts.
  • Added additional fields to the access point information tab.
  • Added a grid to the signal survey when no background image is loaded.


  • Hidden access points will now always be issued with a consistent “Hidden #n” number.
  • Channel width representation on bar charts was overflowing and appearing too large.

APHound V1.4 – Dev complete, finally!

Well, that took longer than expected - and in the end I bumped a couple of “would be nice” updates from v1.4 to v1.5.

But, I got the two big items for this release finished – support for 5GHz WiFi and 802.11ac support. Both of those took longer than I’d planned but that was simply because I didn’t like the way the code was evolving and decided to refactor some more of the 2.4GHz code to make it useful to 5GHz.

Apart from those two big items there’s also:

  • A bug fix for the way hidden networks are displayed.
  • Some additional fields on the Access Point Info tab.
  • A grid on the signal survey display when there’s no background image.
  • The main splitter control position is saved between runs of the application.
  • Libcurl has been dropped in to replace native API calls.
  • The chart legend boxes have been removed and the entries on the access point list are now colour coded.

So, a decent mix of changes.

Final testing should hopefully complete over the weekend and a release is planned some time next week.

Lift-off for V1.4

APHound v1.4 development has been slow to get off the ground this month but I’m finally moving it along. The slower start is just down to one of those Micro ISV realities – having two jobs. The bulk of your time is still taken up earning a living, which fortunately for me means doing the thing I enjoy most - software development, and most of your “free” time is taken up with your Micro ISV.

But hey, any excuse to code!

So, v1.4. The main driver for this release is to add support for 5GHz Wi-Fi. I’ll also be finishing off the support for 802.11ac which I started in v1.3. The changes to detect 5GHz, and 802.11ac capable, access points are already up and running and the initial information display and RSSI tracking is good. Next up is handling the channel allocations.

The Trello board for v1.4 has a few other things on it – internal download of updates, additional fields on the access point information tab, some internal refactoring and a couple of minor bug fixes – but the slower than normal start and the desire to keep up the, roughly, monthly release cycle might push some of these things in to v1.5.

The other item of note this month is that I started the first Google AdWords campaign. I purposely waited until I had a couple update releases complete before I undertook any form of advertising since I knew there were some improvements I wanted to make before I was happy with APHound.

The initial AdWord stats are much better than anticipated and, after a few tweaks to the ads and the keywords, the traffic to the website has grown massively. I’ll let the first campaign run its course then sit down and look at the user/website interactions which will help drive the next website update.

V1.3 Released

APHound v1.3 is now available.

This release was, primarily, to add the extended access point information tab but it also includes a number of additional enhancements and fixes.

New Features

  • Added a new tab to show extended access point information for Plus Edition users.
  • Added the capability, for Plus Edition users, to vary the time between Wi-Fi scans.
  • Added the capability to display 40Mhz wide channels on the access point list and channel charts.
  • Added the display of Co-Channel and Channel Overlap counts for Plus Edition users.


  • Display the MAC address on the bars on the channel charts.
  • Reduced flickering on data lists.
  • Selected interface is now remembered.
  • Selected access point is brought to the front of the channel charts.
  • Numerous internal enhancements to improve the responsiveness of the user interface and the handling of data.


  • Fixed issue where supported data rate information could contain duplicate values.
  • Fixed issue where hidden access points could be displayed with a zero MAC address.
  • Fixed issue where the presence of a 5Ghz access point could cause APHound to crash.
  • Fixed issue where the channel chart doesn’t always show all access points.
  • Fixed issue of out of range value being used for the allocated channel on the access point list.
  • Fixed spacing of adjacent channels on the channel totals chart.

APHound V1.3 – Code complete…phew!

V1.3 turned into one of those releases that sometimes comes along – so much fun (is that wrong?) that there was always room for just one more thing. But I finally stopped and reached code and test complete. I just have the help file and website changes to do and it’s good to go.

I did add the new Access Point Information tab, which was the main point of the release, which contains a little more information than the access point list for each access point. It allows access point data to be displayed side-by-side for comparison.

Looking at the Trello board there’s also a bit more in this one, such as:

  • A couple of bug fixes
  • A good chunk of refactoring
  • Support for channel bonding/40MHz channels
  • A co-channel and channel overlap count
  • User selectable scan intervals

I finally took delivery of a 5GHz, and 802.11ac, capable access point and USB dongle which allowed me to do some initial testing to identify the changes required to support 5GHz networks. That looks pretty good already and it’ll form the basis of V1.4.

I had a good look through the APHound Trello board to try and plan a bit further out. There was enough detail to plan not only V1.4 but also V1.5 and V1.6 too. But enough of that, I need to get V1.3 out of the door first.

APHound V1.3 in full swing

Progress, so far, on APHound V1.3 in April is proving to be much better than V1.2 was in March. The development of this release just seems to be flowing a bit better.

Looking at the Trello board for APHound there’s a bit of a mixture in this release. A few minor bugs fixes, a new feature and tab for the Plus edition and a chunk of code refactoring in preparation for future changes.

The new feature/tab is for displaying more detailed information on each access point and to allow side-by-side comparisons of the data from multiple access points.

I’m also hoping to squeeze in the display changes for access points which can utilise secondary channels.

Refactoring wise, there’s some more efficient data handling and interpretation of the data returned from the scans along with improvements in string and display scheme handling which will enable future customisation.

I also, finally, ordered 5GHz kit to allow development of support for 5GHz access points. I haven’t fixed which release that will appear in but a quick scan of the Trello board would place it in V1.4/V1.5.

Back to it!

The sloooooow month.

A period where the output from development slows happens from time to time. Usually it’s down to the optimistic developer under estimating a task, unexpected bugs or some external time soak. This month has been like that, but with an added “planning to put too much into the next release” tagged on.

To stick to the “release early, release often” mantra I’ve decided to release the one new feature I’ve added over the past few weeks. It’s a new chart which shows the channel allocation and signal strength of each reporting access point.

I had this chart in an early version of APHound but decided against releasing it because I could never get enough clarity in the display of the data when the number of access points grew. It just looked jumbled. But I was tweaking the colour and opacity of the bars in the chart and I think it now looks good enough to release.

This feature will be for the Plus version only since I’ve decided that version needs more to differentiate it from the Free edition.

All going well I should have a new release out this coming weekend.
