Using regular radio for DFing a wifi transmitter is not such a good idea.
The channels overlap, higher data rate transmissions use spectrum
spanning several channels, and many stations transmit on the same
frequency, so with a plain received you will hear a cacophony of sounds,
making it almost impossible to find the station you're looking for. 

You will get much better results using a good wifi card with SMA
connector (Alfa cards are great for 2.4G band) with a directional
external antenna and airmon-ng from Aircrack-ng package to monitor signal
strength for the station you are interested in.
Don't buy those cheap 2.4G yagis from ebay or amazon. They are junk.
You'll get much better results with a home-made cantenna, orheck Andrew
Mcneil's channel on youtube if you need some inspiration:

WiFi features short packets.  You can tune in on an access point and hear
the clicks.  You could try with a highly directional yagi or time of
arrival rig.


BTW Transmitter Hunting is highly recommended but is mostly VHF.

Is it possible to find a WIFI station with direction finding?
