I do this on all my laptops. The issue (which should be in an FAQ) is that your station is reassociating to the ap, typically because you are idle. Each time this happens the link state goes down+up. The dhcp lease is not relevant. You might be able to tweak ap parameters to increase the idle timeout but aside from the link state msgs there's no reason to. Sam
