Is the problem you described in the first message on this thread something different or is this still expected to be the same issue? I'm trying to understand the part about this being somehow tied to scanning (NM enabled vs. disabled). Does this happen if you have NM disabled (i.e., nothing triggering background scans)? > This is from wpa_supplicant (latest version from GIT of course): > > CTRL-EVENT-SCAN-RESULTS .. When you have a chance to run this again, I would be interested in seeing more details debug log from wpa_supplicant (-ddt on command line). From this excerpt, it seems like the issue would not be in association, but on something after that. This kind of log could be produced, e.g., when EAPOL frames are not delivered at all for some reason, but the log does not have enough details to confirm whether that was the case. > Trying to authenticate with 00:1f:3f:19:d8:b7 (SSID='Holtmann' freq=2462 MHz) > Trying to associate with 00:1f:3f:19:d8:b7 (SSID='Holtmann' freq=2462 MHz) > Associated with 00:1f:3f:19:d8:b7 > CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys Would you happen to have any idea on how timing for the last two entries, i.e., how long time it took from association to disconnection? > wlan0: RX ReassocResp from 00:1f:3f:19:d8:b7 (capab=0x431 status=0 aid=2) > wlan0: associated > wlan0: deauthenticated (Reason: 2) This would indicate that the AP accepted association, but for some reason, decided to kick the STA out. Which AP is it? If the deauthentication did not happen immediately after association, this could be indication of failed 4-way handshake; wpa_supplicant debug log would hopefully help in figuring out whether that is the case. If wpa_supplicant log does not show any EAPOL frames, it would be interesting to see a wireless capture log showing all the frames the AP is sending out during the authentication process. -- Jouni Malinen PGP id EFC895FA -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
