>Description:
I've changed my AP at home from WEP to WPA2 and since this one of my
stations facing after some while (~90 minutes) the problem of UP and
DOWN; in /var/log/messages it looks like this:
Jan 21 22:00:09 Perlach wpa_supplicant[485]: CTRL-EVENT-DISCONNECTED -
Disconnect event - remove keys
Jan 21 22:00:09 Perlach kernel: wlan0: link state changed to DOWN
Jan 21 22:00:09 Perlach wpa_supplicant[485]: Trying to associate with
00:13:f7:0d:08:48 (SSID='tarara' freq=2442 MHz)
Jan 21 22:00:09 Perlach wpa_supplicant[485]: Associated with 00:13:f7:0d:08:48
Jan 21 22:00:09 Perlach kernel: wlan0: link state changed to UP
Jan 21 22:00:12 Perlach wpa_supplicant[485]: WPA: Key negotiation completed
with 00:13:f7:0d:08:48 [PTK=CCMP GTK=CCMP]
Jan 21 22:00:12 Perlach wpa_supplicant[485]: CTRL-EVENT-CONNECTED - Connection
to 00:13:f7:0d:08:48 completed (reauth) [id=0 id_str=]
Jan 21 22:00:18 Perlach wpa_supplicant[485]: CTRL-EVENT-DISCONNECTED -
Disconnect event - remove keys
Jan 21 22:00:18 Perlach kernel: wlan0: link state changed to DOWN
Jan 21 22:00:18 Perlach wpa_supplicant[485]: Trying to associate with
00:13:f7:0d:08:48 (SSID='tarara' freq=2442 MHz)
The system runs 9-CURRENT from October 2010 (r214444) and did not show
this problem in WEP mode; wpa_supplicant lines are simple:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
eapol_version=1
ap_scan=1
fast_reauth=1
network={
ssid="tarara"
key_mgmt=WPA-PSK
psk="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
Killing the dhclient(8) processes and restart
# dhclient wlan0
helps to get out of this loop of UP/DOWN.
>How-To-Repeat:
Work and wait until problem occurs.
