The Sidekick 2 is an incredible tool for the wireless network professional. One of its many features is the ability to take over-the-air packet captures on 4 simultaneous channels. If you’re like me, you look forward to decrypting those captures to see L3/L4 information and use it in Wireshark display filters.
The Sidekick 1 and 2 utilize packet slicing to conserve size of capture files by truncating a large portion of the MSDU. In order to decrypt Sidekick 2 captures, Full frame capture mode needs to be enabled. Sorry Sidekick 1 users (like myself), this mode is not available for us. 😦
Full frame capture for Sidekick 2 is enabled within the Analyzer application. While in Ekahau Analyzer, you can enable Full Frame Capture by clicking on the Sidekick Icon on the top right
Now you can capture over-the-air and decrypt PSK to your heart’s content. Oh happy day!
