Hi,
i ported rt2870(ralink) working on mx35. during the test, i met a problem:
first connection  built. the station can ping AP well. 
but  after i power off my AP, i check the interface using ifconfig, i find its status is still active with the AP's ssid
. i have to make it rescan using ifconfig, then the status appears ok.
is there somebody can tell is auto-change status possible? and is it related to 802.11layer or i have to arm the driver 
other features?
