  • Why would you need to use both WAN and LAN to extend a Wifi network?
    Connect the LAN port to either a device or preferably a switch. If you're using this to extend a network, then just extend via wireless.
    What I used to do was, use a powerline to extend the wired network from the DSL modem, to a 10/100/1000 switch, then plug the Airport Express into the switch and set it up so the DSL router created a Wifi network in the front of the house and the Airport Express at the back of the house.

    The only time both WAN and LAN ports would be used together is if this replaces your router or if you're routing at L3 between networks... which I can't imagine you'd want to do on this.
