  BTW, what does that guy mean "Not sure when you updated, but we have changed
  the checked in code to default to 2437, and run it like this (as a NetBSD
  rc.d start script)", following the above link?

details if you care, but surely they have little to do with your issues.

  http://www.netbsd.org/docs/guide/en/chap-rc.html

about your output:

  ./bbn_80211b_rx.py -f 2.437G -v -b
  Bits Per Encoded Sample = 8
  adc frequency =  64000000
  decimation frequency =  16
  input_rate =  4000000
  gain =  45.0
  desired freq =  2437000000.0
  baseband frequency 2432000000.0
  dxc frequency -5000000.0
  Samples per data bit =  8
  >>> gr_fir_ccf: using SSE

  2.432G is used instead of 2.437G.  Also the dxc frequency is negative.  And
  no packets get printed out. 

I am unclear on dxc.

Are you sure there are strong signals at the 1 Mb/s rate on 2437 MHz?

  /adroitgrdevel/gr-bbn/src/examples/bbn_80211b_rx.py just like this:

What operating system are you running on?  That script may be expecting
the NetBSD tap device, and your system's might be different.
