I have a station connected to a couple off SSIDs with connection lists.
But i have a problem when the MT device disconnects from one ssid, and connects to another. the MT does not release and renew its IP on connect to new ssid.

Is there a way i can fix that? Script to automatic release and renew on connect, or restart or anything?

Its a Groove A-52HPn. Only configured with one WLAN, and all connect list items is bond to wlan1.
