I did several surveys of my house today, and kept running into a situation where I’d try to do a measurement, and would get an error dialog that says “An error occurred while scanning Would you like to try again? Device busy”. This happened probably at least ten times throughout the day. It seems like it happened more commonly in borderline signal areas, so I don’t know if this is happening when the OS is trying to re-associate with the AP, or what. But there were a number of times when I kept having to click “try again” until I finally got it to work.

I’m running OS X 10.7.4 on a Mid-2010 MacBook Pro.

Any other software accessing your AirPort adapter at the same time with NetSpot?

Here are some log entries from one of the occurrences. I can email this in (and more) if it’s better (not sure if the formatting will get screwed up here).
