Hi there,

I am currently doing a university project. I am trying to send a text file from one laptop to another over wi-fi, with both laptops connected to the same network. I am then using a third laptop to try and capture the packets of this file transfer but I cannot seem to capture anything coming or going from these two laptops.

Can anyone please help me?

Thanks,

Anish

did you check, and follow, the instructions in the WLAN sniffing wiki?

http://wiki.wireshark.org/CaptureSetup/WLAN

1.) What's the OS on your sniffer machine (Windows, Linux, BSD)?

2.) Is the Wifi connection encrypted? If so: How (WEP, WPA, etc.)?

Regards
Kurt

Hi Kurt,

Thanks for your reply, yes i had a brief look at that a while back but I will look into that in more detail now.

The sniffer machine is windows 7.

With regards to the encryption, the router is encrypted with WPA. However I want to carry out the experiment with encryption on and off. When I tried both these tests yesterday I still had trouble finding anything even when encryption was disabled.

did you connect the windows 7 sniffer machine to the SSID of the test clients?

please consider the limitations of Wifi sniffing on the windows platform. Search for "Capturing WLAN traffic on Windows" in the wiki link mentioned above.

All three laptops were connected wirelessly to the same network.

as menitoned above, please check the wiki and the limitations on windows.
