    Hi,

    First of all I do speak german as well but I prefer to write this in english (more people can read it!!)

    I just want to share my findings after a few hours of debugging WPA / WPA2 WLAN encryption as many other people seem to have troubles as well!!

    1.) WPA/WPA2 config method has changed in version 1.77, there is no separate config / menu entry for WAP and WPA2, this has not been updated in CAS studio (yet), also LANG files have not been changed (new files attached - English and German - copy to \MENU\LANG - its not possible to set key via CI Menu), best way to configure WPA is config.xml file directly, see below.

    2.) If you want to pair Diablo Wifi with a Cisco AP (c1100 in my case) you will encounter problems as soon as you turn on WPA/WPA2. Reason is a timeout during WAP Key handshake.
    Cisco Debug commands (needs level 15):
    debug dot11 aaa manager all
    debug dot11 aaa dispatcher
    term mon


    Now you will see the following during authentication:
    //SNIP
    dot11_mgr_sm_hs_callback: [1] Handshake msg to 0019.2896.2613, timer set: timeout 100 ms
    dot11_mgr_sm_run_machine: Executing Action(WPAV2_PTK_MSG2_WAIT,TIMEOUT) for 0019.2896.2613
    //SNIP

    due to the time-out the authentication will finaly fail:
    //SNIP
    dot11_mgr_sm_handshake_fail: Handshake failure for 0019.2896.2613
    dot11_aaa_send_response: wlccp_ap_auth_method_done 50, method_done 8
    dot11_aaa_send_response: Sending response: 0 for: 0019.2896.2613
    %DOT11-7-AUTH_FAILED: Station 0019.2896.2613 Authentication failed
    //SNIP

    To anyway make the WPA/WPA2 working time-out needs to be set to a higher value (in global config mode):
    dot11 wpa handshake timeout 500

    Then you should get something like that
    //SNIP
    Aug 2 21:19:51.306: dot11_mgr_sm_hs_callback: [3] Handshake msg to 0019.2896.2613, timer set: timeout 500 ms
    Aug 2 21:19:51.335: dot11_mgr_sm_parse_client_pak: Received EAPOL packet from 0019.2896.2613
    //SNIP

    //SNIP
    Aug 2 21:19:51.379: wpav2 Handshake passed
    Aug 2 21:19:51.380: dot11_mgr_sm_handshake_pass: Handshake pass for 0019.2896.2613
    Aug 2 21:19:51.380: dot11_aaa_send_response: wlccp_ap_auth_method_done 50, method_done 8
    Aug 2 21:19:51.380: dot11_aaa_send_response: Sending response: 2 for: 0019.2896.2613
    Aug 2 21:19:51.380: %DOT11-6-ASSOC: Interface Dot11Radio0, Station 0019.2896.2613 Associated KEY_MGMT[WPAv2 PSK]
    Aug 2 21:19:51.380: dot11_aaa_client_associate: Associated 0019.2896.2613
    //SNIP

    AW: Diablo WiFi and WPA / WPA2 Problems + Solution

    Lightning01, great work, well done.

    Most Diablo WiFi problems are caused by unreliable WiFi connections on one side, the other part may be configuration problems. Will investigate your findings.

    Thanks again!!!

    Lasst mich wissen falls ihr das nicht lesen könnt. Übersetzen ist kein Problem.

    lesen schon und das ganze funktioniert auch, allerdings nicht mehr nach neustart bzw aus und wieder einschalten des Fernsehers.. er findet mein Netzwerk auch immer wieder, allerdings verbindet er nicht vernünftig wenn ich es einfach übers WiFi-Menü-Steuere..
