I like having this utility because it seems to find WiFi signals that the airport menu either doesn't see or is slow to see. Also gives a lot more info, which can help you know how to best build a network that reaches everywhere you want it to. However, I was a bit disapointed with a bug I think I found. My MBP just had to be repaired, which made it seem like a new computer. Re-authorizing iTunes and other apps was easy enough, but each time I tried to launch AirRadar it asked for my Mac App Store password and then never launched. Finally had to delete the program and reinstall it.

I have used this program in it multiple versions. I find it gives me all the information I need for the wireless access points visible to my Mac. The interface is easy to use and intuitive. You do need to know something about wireless technology, but if you do - this program gives you a great deal of detail. I would give it a 5 star if it had some tutorials for non-techies - then I would recommend to my non-technical friends.

I am sure that this app can do a lot more than I have asked of it, but it was very helpful for me in identifying that my AirPort Extreme was insisting upon selecting channel 1 in spite of the fact my next door neighbor was also using channel 1. I forced the change to channel 11 and the performance is much better now. This cost of this app was well worth it for the clarity I now have.

I have used AirRadar for several years now and I find it to be an invaluable tool in identifying and solving WiFi (a.k.a. Airport) network issues. There are lots of apps that provide similar information about the WiFi environment but AirRadar provides all of the information needed in a concise easy to understand formats. The channel suggestion feature is a great time saver and invaluable when setting up wireless networks in a crowded environment.
