Thread: Atheros wifi WPA problem

  1. #1

    Default Atheros wifi WPA problem

    Im, not sure what causes the problem, but after instalation of Suse 11.4, wifi worked totally correctly, until the first restart. Then it ceased to work. It looks like everything is working correctly until WPA authentication.

    My wifi device
    Code:

    iwconfig and iwlist output:

    So until now it looks for me that everything works correctly, but after trying to connect the problems begin.

    dmesg output:

    [  233.984142] wlan0: deauthenticating from f0:7d:68:79:1c:ba by local choice (reason=3)
    So the wlan interface authenticates, and then disauthenticates by local choice?
    Googling a bit about the reason points to wpa_supplicant. Many peoples report that they have multiple copies running, and killing them solves a problem. Sadly I've only one copy, and after being killed it restarts.

    Here is wpa_supplicant.log on the first run after install(when it worked)
    Code:
    Trying to associate with f0:7d:68:79:1c:ba (SSID='dlink' freq=2462 MHz)
    Associated with f0:7d:68:79:1c:ba
    WPA: Key negotiation completed with f0:7d:68:79:1c:ba [PTK=CCMP GTK=TKIP]
    CTRL-EVENT-CONNECTED - Connection to f0:7d:68:79:1c:ba completed (auth) [id=0 id_str=]
    WPA: Group rekeying completed with f0:7d:68:79:1c:ba [GTK=TKIP]
    WPA: Group rekeying completed with f0:7d:68:79:1c:ba [GTK=TKIP]
    And here is log of what happens after restart:
    Code:
    Trying to associate with f0:7d:68:79:1c:ba (SSID='dlink' freq=2462 MHz)
    Associated with f0:7d:68:79:1c:ba

    CTRL-EVENT-DISCONNECTED bssid=00:00:00:00:00:00 reason=0
    CTRL-EVENT-TERMINATING - signal 15 received
    I will be grateful for any help here. Sadly I've no way to change from WPA authorization.

    Default Re: Atheros wifi WPA problem

    NetworkManager or ifup? KDE or Gnome?

    If NM, look at /var/log/NetworkManager.

    Between installation of 11.4 and the first restart, was there an update? In
    particular, was a new kernel installed?
