XWLAN does not reconnect after connection drops

[andib]

Some people complained about not reconnecting after connection drops but keep in 'searching...' state. This ticket is to collect the infos.

Paperino	Andi_aw: first, it does not start dhclient itself...
...
Paperino	Andi_aw: where is your dhclient exe located? here in d:/usr/sbin/dhclient.exe
...
Paperino	Andi_aw: 2nd issue: sometimes here connection drops for some unknown reason; then xwlan enters 'searching...' state and it never reconnects to wlan.
...
Paperino	Andi_aw: closing xwlan and restarting it correctly connects to interface.
Paperino	Andi_aw: closing xwlan and restarting it correctly connects to wlan.
...
Andi_aw	connection drop is a dhclient or wpa problem?
Paperino	Andi_aw: ah dhclient does not close...
Andi_aw	dhclient is killed whenever switching between profiles or activate/deactivate (better solution would be signals to dhclient)
Paperino	Andi_aw: dhclient is not killed when searching for networks
...
Andi_aw	OTOH when connection only drops for a short time, the 'old' IP should be valid anyway, isn't it?
Paperino	Andi_aw: yes, xwlan window changes bitmap and instead of signal level shows brown bars. The tooltip says 'searching for networks' and never ends...
...
altsan	I sometimes see that on certain networks.
altsan	Especially when connecting to my smartphone WiFi tether

Paperino	Andi_aw: XWLAN closes wpa supp when network disconnects... and wpa window is not visible while searching.
