Hello all,

So I recently got an Airport Extreme and hooked it up to my Westell modem (model: C90-610030-06). Innitially I had the router bridging to the modem, but I wanted it the other way around. So I turned the modem on bridge mode and disabled the LAN dhcp (had to do both to get rid of the "double NAT error"). In Airport Utility, I then connected using PPPoE (previously via DHCP but there was an "internet connection" error and switching to PPPoE solved that). And the router is in DHCP and NAT mode. I also added the iMac, that the router is hooked up to via ethernet, to the DHCP reservations.


On the Airport Extreme, the light is green. The Airport Utility shows no errors. However, the light next to where it says "Internet" is orange. At this point, Im confused how to resolve this problem. I've spent so many countless hours resolving the double NAT issue (despite putting the modem on bridge mode) that I am done fiddling around with this.


I realize I might be missing something obvious so ANY help would be appretiated. Ill be glad to give any more relevant info if needed.

Also, I really don't want to go through the hassle of solving my problem any other way than the route I've taken. I realize it might not be the most "efficient" but it's what I need to do.

Airport Extreme, OS X Mountain Lion (10.8.2)

    Bridge Mode on the modem and Connect Using = PPPoE on the AirPort Extreme would be the correct way to configure things if you are using ATT.


    You don't mention what service you are using, but most DSL providers would be compatible with the same type of setup.


    You may have already done this but it typically takes several modem and router power downs and restarts whenever you are making configuration changes on both the modem and router.


    Try powering off the modem, waiting a minute and then restarting. Then do the same with the AirPort Extreme while the modem stays "on".


    If that does not work, it might be good idea to set up a temporary or test PPPoE connection on the Mac and see if the modem will work correctly when it is connected directly to the Mac. Post back if you are not sure how to do this.


    If things work this way, at least you know the modem is working correctly in Bridge Mode.


    If you still cannot get an Internet connection during this "test".....when the modem is connected directly to the Mac.... then you know that the modem is either not configured correctly, or it is simply not functioning in Bridge Mode. More modem work will be required.


    If you can get an Internet connection when the modem is connected directly to your Mac, then we'll try to get the AirPort Extreme working.


    Important......Remember to delete or inactivate the PPPoE connection on the Mac now.....before  you connect the modem to the AirPort Extreme......since you cannot have two devices on a network both trying to initiate PPPoE service.

    I'm more not sure as to what you mean by this


    What I mean is that IF the modem really is in Bridge cannot then connect the modem directly to your computer and get an Internet connection that set up a special connection on the computer.


    You won't have to worry about this if you can get the AirPort working with the modem.

    I don' have a Westell modem, so cannot test that aspect of your setup. I do have an older Motorola ATT 2210 modem, which I configured in Bridge Mode and then set up a spare AirPort Express here to connnect using PPPoE.


    As luck would have it, things worked fine the first time that I powered things up. I've since tried to "break" the connection to try to figure out why your setup is not working. So far, I cannot duplicate the errors that you are reporting.


    So, here are the possibilities:


    1) The modem is not really in Bridge Mode....or if it is not functioning correctly. Please verify that you have gone into the modem settings using a default IP address....something like for example only....... to bring up the configuration pages for the modem and then chosen the Bridge Mode setting, saved the configuration, etc.


    2) The AirPort's PPPoE settngs are not working correctly. Here, I assume that you have entered your ATT user name and password in the setup of the AirPort.


    So, to summarize.....we do not know whether you have a modem problem....or an AirPort problem....or both devices are problematic, which is possible, but not likely.


    There is a way to find out whether the modem is working correctly in Bridge Mode.....and that is to set up a PPPoE connection on your a temporary test. In this test, your computer would simulate the PPPoE connection from the router.  You would keep the AirPort Extreme powered off and disconnected during this test process.


    If you connect the modem directly to the Mac....and if the computer can connect using a PPPoE setup on the Mac (I will tell you how to do this).....then you know that the modem is working correctly in Bridge Mode. So that eliminates one of the possibilities above and points to the AirPort Extreme as the device that needs more troubleshooting.


    Does that make sense? Do you want to do this?

    Power off the AirPort Extreme

    Disconnect the Ethernet cable from the modem


    On your Mac.......


    Open Sysem Preferences

    Open Network

    Click the small + (plus) button at the bottom of the connection list on the left

    Click on Interface and select PPPoE

    Click Create


    Now Click on the new PPPoE connection on the left column


    On the right, leave the Service Name area blank

    Under Account.....enter the ATT user name

    Under Password....enter the ATT account password


    Connect the modem directly to the Ethernet port on your Mac

    Turn off wireless on your Mac if it is on


    Click Connect


    Wait a minute to see if the Mac's PPPoE connection service will work with the modem


    See if you can get an Internet connection on the Mac


    If you can.....then you know the modem is working correctly in Bridge Mode


    If you can't....then you know that the modem is not working correctly.

    I assume that you remembered to disable the PPPoE connection on the Mac when you connected the modem back to the router.


    The bottom line to all of this is that the modem is working correctly in Bridge Mode, (you verified this by having the Mac connect directly to the modem in the test), but the router is having problems providing the PPPoE service to allow a valid Internet connection.


    There are no more settings on the AirPort that can be adjusted or changed in this regard, so if your goal remains to have the modem in Bridge Mode and the AirPort provide the DHCP and NAT service, you will need to try another AirPort.


    This connection method has worked correctly for me for years with an AirPort Extreme and a modem configured in Bridge Mode.

  • Bob Timmons Level 9 Level 9 (75,470 points)

    Please provide a screen shot to verify that the modem is set up to operate in Bridge Mode.


    Some of what you are telling me now indicates that it is not...and you told us it was. All of our instructions assumed that you were providing correct information.


    For example, you could not have a Double NAT error if the modem is in Bridge Mode since NAT is turned off on the modem when it is configured in Bridge Mode.
