There are many resources available to learn about using SDR hardware, I
would particularly recommend the video series that Mike has made available
here: http://greatscottgadgets.com/sdr/

The easiest was to get started is to use a tool such as GQRX or SDR# and
take a look around the spectrum.  You can leave your gain settings fairly
low (amp off) and should be able to pick up local FM stations, see adb-s
traffic, etc

HackRF One is able to receive in both of those bands, but decoding modern
wifi with SDR may require some software development and in many cases isn't
possible due to hardware constraints.  Wifi channels are a variety of
widths, 802.11b/g use 20MHz bands, which can be captured with HackRF One,
but newer wifi variants use 40 or 80MHz channels, which is far too wide for
most SDR hardware to receive.

The most promising 802.11 SDR project that I've seen is here:
https://github.com/bastibl/gr-ieee802-11  It is installable using pybombs,
but I have never tried it.
