[Discuss-gnuradio] Capture and plot 802.11 frames

[Stratos Keranidis]

Hello,

I am a new user of the GNU platform.

I managed to install the paltform on my Ubuntu 10.4 PC

and I am currently trying to capture 802.11 frames that are transmitted in my

WLAN.

I am using these tools:

usrp_oscope.py -f 2.412G

uhd_fft.py -f 2.412G

All I can see is noise on this frequency, although I confirm that packets are transmitted between my PC and my router on this frequency.

Does my problem have to do something with the settings of these tools or do I miss something else.

Can you provide me with some tutorial link, where I can find more info on the basic usage of USRP?

Thank you in advance,

Stratos.
