I have an cisco 340 card with the latest driver from sourceforge (airo-linux), running on the 2.2.18 kernel. I am able to intercept unicast traffic in promisc mode.
Problem: I can't intercept encrypted traffic. I know this must be possible, but how do I go about it? Either the current driver, firmware doesn't pass the traffic to my network stack. I want to test WEP vulnerabilities on my network, but need to be able to see encrypted traffic.
