Using Wi-Fi - if you then plug in Ethernet, does Ethernet take over?

    Hypothetical scenario - I'm browsing the net on Wi-Fi on my MBP, and then I decide to go back to my desk and plug in the Ethernet cable... will the Ethernet take over from the Wi-Fi connection?

    This is of course presuming that the two connections (Wi-Fi and Ethernet) are set up to be identical - same IP on the LAN (i.e. no DHCP), same subnet, same router/DNS server address, etc. etc.

    Anyone?

    Don't have a convenient way to check this right now but it is determined by the 'Service Order' set on the Network System Preferences pane (click the Gear icon at the bottom of the network list pane).

    IIRC it's Bluetooth DUN/Ethernet/Firewire/Airport by default, so assuming yours hasn't been changed the answer is yes, your Ethernet connection will take priority.

    And you don't have to (and shouldn't) set the same IP and so on. Just let DHCP take care of it, it just works...

    You could verify the change in priority under network under (system) preferences.
