1. Which tool is better at performing protocol captures and which tool is better at performing protocol analysis? Wireshark is better for performing protocol analysis and Netwitness Investigator is best at performing protocol captures. Wireshark does well at both aspects‚ which makes it a little better. 2. What is promiscuous mode and how does this allow tcpdump‚ Wireshark‚ and NetWitness Investigator to perform protocol capture off a live network? Promiscuous mode is for a wired network

Troubleshooting Tips I Cannot Capture the Four-way Handshake! It can sometimes be tricky to capture the four-way handshake. Here are some troubleshooting tips to address this: Your monitor card must be in the same mode as the both the client and Access Point. So‚ for example‚ if your card was in “B” mode and the client/AP were using “G” mode‚ then you would not capture the handshake. This is especially important for new APs and clients which may be “turbo” mode and/or other new standards
