decrypt

I am trying to decrypt my WLAN data with Wireshark. I have already read and tried eveything on this page but without any success (well, I tried the example dump on that page and succeeded, but I fail with my own packets).

I caught the four-way handshake from another client connecting to the network.

My network info is as follows:

SSID: test
Passphrase: mypass
The above info would give this preshared key: 58af7d7ce2e11faeab2278a5ef45de4944385f319b52a5b2d82389faedd3f9bf

In Wireshark in the Preferences-->IEEE 802.11 I have set this line as Key 1:

wpa-psk:58af7d7ce2e11faeab2278a5ef45de4944385f319b52a5b2d82389faedd3f9bf

I have tried the different options of "Ignore the protection bit" but none works.

What could I have missed?

Is there any way to save Wireshark capture options? So it can be reuse after restart Wireshark. Also, if the saved file is in plain text, it's possible to use scripts generating bunch of capture settings, such with different filter setting. Does anyone know? Thanks. >>> More
