Hi there, the question is: How to make wpa_supplicant renew the IP address when device connects to another wi-fi access point? If I manually run dhclient wlan0 - it renews IP and all ok. But I must do it automatically after reconnect to another wi-fo spot.

I read about roaming but it doesn't the trick. I hoped on /sbin/wpa_action but it don't runs too, I placed post-up hook on interface, but wpa_supplicant even doesn't down/up it.

OS: Ubuntu linux
