How do I view wireless Clients' signal strength on AirPort Extreme?
On a Mac:
I used to be able to see the signal levels and signal to noise levels with Airport Utility. It looks like that screen has been deleted from the utility. It was useful when picking frequency bands to use to ensure I wasn't getting interference from other nearby networks. I realize that the Extreme Base Station does automatically select the frequencies for me, but when I first hooked mine up ( a year ago or so) I was able to improve on the automated process. I've read that the automated process has improved. apparently Apple thinks that it's improved so much that there's no need to inspect the result with Airport Utility......i.e. it's lost some utility.
Is there some free or inexpensive utility available that will do this that is Mac compatible, reasonably accurate, and reliable?
