    Hello everyone,

    This may have been asked before, but I couldn't find an answer to my specific problem. I am living in an apartment where wifi is provided. I have access to the modem and router as well as their settings, but cannot directly connect to them. I am using my Airport Extreme to join this network. This works well for all of my wireless devices, but when I try to connect my desktop via ethernet to my Airport, it cannot connect to the internet. When I plug my Macbook into the ethernet, the Network pane tells me the following: "Ethernet: Connected. Ethernet is currently active and has the IP address" However, Safari tells me I am not connected to the internet.

    The Airport is set up to join a wireless network. When I select "Extend A Wireless Network", it tells me "The network you selected cannot be extended." The router is a Cisco, so I am not as familiar with the interface as I am with an Airport's. There is no obvious "allow this network to be extended" equivalent, but there may be another way that I am unaware of.

    So my question is, is it possible to wirelessly join a network with an Airport, and then connect a computer to that airport via ethernet?

    Choose 'join a wireless network' and then check the box 'allow ethernet clients'.

    I think this doesn't exist on older airport units. It may require a firmware update?

    I use this all the time.

    Thanks for the quick reply!

    I am running firmware 7.6 , but I don't see this option. After clicking on Manual Setup, I select "Airport", then "Wireless". Am I looking in the right spot? I don't see it anywhere else either, but I may have missed it.

    EDIT: My Airport Extreme is an 802.11n, model A1143, MA073LL/A, Jan 2007.

    What model of Airport Extreme are you using? What firmware are you running? I'm curious as to what the difference in our setup is.
