Our floor has a blind spot so we needed to place an AirPort to cover two rooms. The AirPort in this particular room is transmitting at a higher power than needed, and its bleeding onto some areas where its unwanted. (This was found with Wifi Stumbler).
I'm running the AirPort Utility on OS X Mavericks. The room in question has an AirPort Express. I've looked in the AirPort Utility, but I don't see where I can set TX power.
How do I turn down TX power on AirPort?
Is there some sort of secret knock to use with AirPort to get into advanced settings? Or should I be using something else to configure them?
