Actually A while ago, it was discovered Atheros ath9k and ath10k based wifi cards have a spectrum scan feature. There was some work in reverse engineering the data format. I'm not sure if theres been similar developments for recent devices.

You'll need a wi-spy dongle, SDR or something similar. A standard wifi card won't identify any interference it doesn't recognise as a wifi signal.
