Any idea what might be the cause of this failure to connect? I don't know much
about the setup of the AP at this point.
sta101: SME: Trying to authenticate with 10:51:72:54:5a:90 (SSID='pmftest' freq=5180 MHz)
1415248099.342285: sta101: Trying to associate with 10:51:72:54:5a:90 (SSID='pmftest' freq=5180 MHz)
1415248099.354882: sta101: Associated with 10:51:72:54:5a:90
1415248099.360457: sta101: WPA: CCMP is used, but EAPOL-Key descriptor version (3) is not 2
1415248099.360497: sta101: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=GB
1415248100.853397: sta101: WPA: CCMP is used, but EAPOL-Key descriptor version (3) is not 2
1415248102.355151: sta101: WPA: CCMP is used, but EAPOL-Key descriptor version (3) is not 2
1415248103.850210: sta101: WPA: CCMP is used, but EAPOL-Key descriptor version (3) is not 2
It appears the code that is complaining is this:
(from wpa.c)
if (sm->pairwise_cipher == WPA_CIPHER_CCMP &&
ver != WPA_KEY_INFO_TYPE_HMAC_SHA1_AES) {
wpa_msg(sm->ctx->msg_ctx, MSG_INFO,
"WPA: CCMP is used, but EAPOL-Key "
"descriptor version (%d) is not 2", ver);
if (sm->group_cipher != WPA_CIPHER_CCMP &&
!(key_info & WPA_KEY_INFO_KEY_TYPE)) {
/* Earlier versions of IEEE 802.11i did not explicitly
* require version 2 descriptor for all EAPOL-Key
* packets, so allow group keys to use version 1 if
* CCMP is not used for them. */
wpa_msg(sm->ctx->msg_ctx, MSG_INFO,
"WPA: Backwards compatibility: allow invalid "
"version for non-CCMP group keys");
} else
goto out;
version 3 appears to be: WPA_KEY_INFO_TYPE_AES_128_CMAC
Config file is below.
