AP Grapher is a freeware program for Mac OS X which searches for nearby wireless (i.e., WiFi, Airport) access points and graphs the signal strength as a function of time for the base station you are currently connected to. Although the program has a "stumbler" like mode, it's not a true a stumbler in the classic sense since it only finds visible networks.

AP Grapher is intended to help you find the best access point to connect to and optimally position your base station and or computer to achieve the best possible signal strength.

What's New

Version 1.2.1

[new feature] Newly designed larger icon.
[new feature] Added optional menu extra to display the comm quality as a percentage.
[new feature] Added option to speak comm quality as it changes.
[new feature] Scanner now remembers which column to sort by and by default sorts by signal.
[new feature] Minor internal updates.
[other] Dock icon graph now draws translucently on top of the dock icon and is based on the time elapsed rather than the number of samples elapsed.

Version 1.2

[new feature] Leopard (Mac OS X 10.5) compatibility resulting from a major internal re-write.
[new feature] Scanner now shows noise and MAC address in addition to other fields.
[new feature] Option to include or exclude ad hoc networks from the scanner list.
[new feature] Optional scan sound played at completion of each scan.
[new feature] Other small changes to the interface, preferences, and internals.
[bugfix] SNR (signal to noise ratio) should now be correctly computed and graphed in all cases.
[other] Removed ability to graph raw signals since it turns out that comm quality is just normalized raw (no need to have them both).

Version 1.1:

[new feature] Added toolbar button to open the Network System Preferences.
[new feature] Added count of discovered base stations to scanner.
[new feature] Base stations are now keyed based on their MAC address rather than name, so stations with duplicate names won't overlap each other.
[new feature] Added readouts of the time width and current transmit rate to the graph window.
[new feature] Dock icon graph now draws vertical user set marks like the full size graph and draws all the way across when the preference to fit to graph width is set.
[new feature] Preferences window now remembers which tab was previously selected and returns to it.
[new feature] Added option to save graph to a PDF or scan to a text file.
[bugfix] Signal, noise, and SNR graphs now jump to the bottom rather than the top of the graph when AirPort power is turned off or the connection is lost.
[bugfix] Fixed another memory leak; this appears to be the last one.
[bugfix] Addressed an issue which prevented the scanner from displaying nearby access points on some computers - particularly Intel based Macs. The names were spoken but not displayed.
[bugfix] Improved robustness of scanner in general.
[bugfix] Core 2 Duo laptops report the scanner signal strength in negative values whereas all other Macs seem to use positive values. Addressed an issue which could either cause a crash, or prevent the best signal strength from being colored correctly on these computers.
[other] Scanner and grapher now keep running even if all signals are lost or AirPort is turned off.

Version 1.0:

[new feature] Major rewrite which changes the way signal strength is obtained from the system.
[new feature] Now works with Intel based Macs such as the MacBook and MacBook Pro (universal binary).
[new feature] New scanner feature (similar to a stumbler, but only visible networks).
[new feature] Option to add vertical marks to the graph to compare signal strength at different times.
[new feature] Reorganized and hopefully simplified interface.
[new feature] New help documentation using Apple's help viewer.
[bugfix] Small memory leak fixed.

Version 1.2.1

[new feature] Newly designed larger icon.
[new feature] Added optional menu extra to display the comm quality as a percentage.
[new feature] Added option to speak comm quality as it changes.
[new feature] Scanner now remembers which column to sort by and by default sorts by signal.
[new feature] Minor internal updates.
[other] more...

"...now broken and abandoned."

Yep.

Crashes upon opening with OS 10.7.1.

I liked this app a lot. But it seems to have stopped working after I installed Snow Leopard. Here's hoping that the developer continues to update this nice application.

The application allowed me to find the pest placement of my wireless router. however it did keep unexpectedly quitting on me.

I learned of AP Grapher on the Apple Discussion board dealing with the MacBook Pro dropping Wi-Fi connections. Grapher is a great way to track connectivity and confirm that there is a 'drop' even though the Mac 'Radar' says there is a strong connection. Grapher worked perfectly right from the getgo on my MBP Intel Core Duo 2.16 GHz running 10.5.2 (and now I have the evidence that the MPB is dropping the connection). Thanks.

Excellent.

I like the 'hide inactive stations' and 'hide secure stations' options.

Same here on a MBPC2D
It does look nice though - can't wait for an update!

Does the problem still occur with Airport Update 2006-002?

Doesn't work with MacBook Pro Core 2 Duo - probably needs updating to cope with 802.11n cards that appear in these machines.

A new version of AP Grapher is in development which adds support for Intel based Macs; it should be released within a few weeks. A screenshot is available at the AP Grapher home page.

I have come to like the simple interface of AP Grapher vs iStumbler's. But, the signal and noise graphs have never shown up. I have only get to see the Link Quality and Comm Quality.

Any comments on that?

"Any comments on that?"

Yes.

Have you asked (emailed) the developer or checked the developer's website?

A new version of AP Grapher is in development which fixes this problem as well as adding support for Intel based Macs. A screenshot is available at the AP Grapher home page.

AP Grapher helped me in comparing my ADSL WiFi router settings. Changing from channel 11 to 10 leads (for my config) to a near 10% signal gain.
The graph displays the benefit instantaneously while I change the channel on the fly.

HINT: the editor says that the SW consumes extra CPU when graph reachs the left side of the window as it has to refresh the scrollbar.
Simply set a buffer value less that the window's width an your done with this leak :-)

I do not know what is happening with this app.

It crashes a lot on MacBook Pro 17 inch 2.16 with 10.5.6. I mean a lot!
