1 second. I am aware that this interval is only useful for a testing

I tried it. If we change from one accesspoint to another(with a

DHCP-requests anything else. You can compare it to networks, where
wireless and wired network are bridged. You can change the
accesspoint, but everything else, on higher layers, stays the same.
