==========================================
while roaming i see the disconnect and reconnect happens immediatly.Roaming is happening between 2.4GHZ to 5GHZ and vice versa.
a. Whether the disconnect happening in the roaming is expected? it immediatly reassociate.
b. However when you issue the wpa_cli -iwlan0 disconnect. i see the device is trying to associate taking more time.
