SPAN code - receiving data frame

Hi all,

I implemented SPAN code in usrp-1, gnuradio -3.3.0 … (downloaded SPAN
code
and modified to work with 3.3.0 version)

I changed my lap’s wifi datarate of 1Mbps using iwconfig command and i
received Beacon frame…i got this correctly.

Then, i connect another lap to ad-hoc network and used usrp-1 as
sniffer… I
am receiving Beacon frame correctly but when i am loading the file
through
wifi, i am not getting dataframe correctly…

its showing packet length as 10 once i start loading file… also i got
some
dataframes of length 1580 (very less when compared to frames of length
10)

Will SPAN code receive 1Mbps dataframe??
