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.

"...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.

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!

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.

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.

This is very useful for trying to find out the coverage of your wireless router. I used this at my church for figuring out where our WiFi "dead spots" were, and where the card tends to switch from one hot spot to another (since we have three to cover the entire building).

It's also very useful in tandem with KisMac, having KisMac automatically connect to any open network while wardriving. Leave both windows open so you can see both easily, and you can use AP Grapher to get in a good position for best reception.

Note to those who asked about certain features not graphing (like noise, signal, etc): Those depend on your computer and wireless card. Certain AP cards will not provide data for those features, some will. I don't know off the top of my head which ones do what, but at least you can know why. :)
