That is entirely done by wpa_supplicant. Yes I do but I also want to know how the roaming is managed by the wpa_supplicant.

The same is true for the default-route. This is indeed what I want to know but I wonder when it is decided that a connection is down? It could be that the wifi can just be detected but almost no data goes over the network while a good 3G connection is available. Which metric is used to detrmine that the connection is down? > > Not sure if that answers your questions :) > > Thomas |
