Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I am making acquiantance with wireless security and attacks and was told to run some tests with aircrack-ng and wireshark.

So I installed both of them and ran airmon to switch wi-fi card to monitor mode:

sudo airmon-ng start ra0 (this is my DWA-140 usb wi-fi adapter) The wi-fi adapter seems to have restarted after that. Gues that's ok.

After that I ran wireshark as a superuser, chose the ra0 adapter and tried to sniff the test open network. I have my PC connected to it (via dwa-140) and an HTC phone and some stranger PCs. Wireshark runs on my PC.

The problem is that when I login to %sitename% with a PC browser, I can see the cookies sent to it in Wireshark. But when I do the same thing with an Opera browser on my HTC, there is nothing detected. I know that stranger PCs are also sending data to %sitename%, but I see nothing from them as well. Still I see a lot of packets from stranger PCs, but not the ones I need.

I'd like to know what I'm doing wrong. Will be thankful for any advice.

P.S. This runs on Ubuntu 12.04.1

The issue was solved by installing an rt2800usb driver. Now monitor mode can be enabled, though sometimes the connection is lost.
