I have an Xfinity SMCD3GNV modem with wifi.  My AirPort Utility app does not recognize it.  How can I configure it?  Five calls to Comcast/Xfinity didn't help.

Mac Pro, OS X Mountain Lion (10.8.2)

    Airport utility will only recognize your Airport Express/Time Capsule/extreme

    It is an that works with Apple Routers only.

    If you are trying to configure the modem you got from comcast, I would suggest first, plugging an ethernet cable from your Mac Pro into the comcast modem. Then entering the IP address of the modem in your browser. Once you configure your wireless settings, you should be able to unplug and find the comcast modem through your wireless signal.

    Ok, so first off - your ethernet cable is plugged in.

    1. Are you able to access the internet?


    2. Click System Preferences, Click Network.

    You should get a window pane that says status: connected, down in that list look where it says Router.

    That address is what you want to type in your web browser.


    Now you may need an administrator password - and that is something that comcast provides you.

    You might try doing a search on the web to find out what it is:

    search "whatever the model is" "brand" and "default password".


    Might be something as simple as

    user: admin

    password: admin


    I just searched for the info:


    Router Login:

    Login Name: admin

    Login Password: password

    So in the browser, the default router address is


    Did you try that address in your browser and hit enter? (safari)


    That is strange that you cannot connect to it.

    I am not sure what you mean "ethernet 2", do you have another connection?

    You may want to consider buying your own cable modem, from what I have seen online that model - people have complained about the range being rather low with those.
