--- Comment #34 from Hans Leidekker hans@meelstraat.net --- In the case where the wlan interface is connected the ethernet interface is still up and running, without an associated IP address. In the working case where the ethernet interface is connected the wlan interface is down.
What happens if you shut down the ethernet interface in the first configuration?
