In general i agree with the idea the always connect to the best network. But problem with WPS is that we have already chosen the best network and due to the disconnection triggered by protocol we may end up with another AP. Again this could be ok from user point of view (as both have same ssid), but this can cause a connection loop if every time after provisioning we end up choosing other (remote case). _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
