I changed ISP as of January 1st and for some reason my Time Capsule does not recognise the new provider. I have internet through fibre that comes to my appartment via ethernet. No modems or other devices between the ethernet connection and the Time Capsule. When I connect my MacBook to the internet via ethernet, it connects within seconds.


I have done several factory resets on the TC but nothing helps. The ISP works with DHCP, which should be the default on the TC after a factory reset.


Otherwise the TC works normaly.


Please help!

    If it doesn't get the IP on the wan interface.. do you need to reboot the fibre to ethernet converter.. sorry but fibre is still pretty new to me.


    Do the connectivity LED go on for WAN port on the TC.


    If not set the speed lower or try a new cable.

  • Hildor Level 1 (0 points)

    Thanks for the quick reply. The fiber comes into our appartment house and we do not have individual converters in the appartments. All I have is an ethernet connection in the wall.


    The WAN-LED on the TC is on (constant green light) and when I disconnect the cable from the TC and put it in my MacBook I have an internet connection.

  • LaPastenague Level 8 (48,844 points)

    Ok.. do you get a public IP through your system.. ??


    If you get a private IP in the range 10.0.x.x then the TC will not work.. it cannot route the same IP it has on the LAN side to WAN..


    Please post a few screen shots of the summary page.. showing the WAN IP.


    Much easier in v5 utility of course. Tell me if you run Mountain Lion and need v5 instead of toyland v6.

  • Hildor Level 1 (0 points)

    I do have a public IP. Please see screen shot below of the TC in v6 utility. I tried to install Airport Utility v.5, but since I already have v 6 installed, I was nor allowed to do so.

    Please let me know if you need any additional information.

  • LaPastenague Level 8 (48,844 points)

    Ok, give me a screen shot of your NAT setup.. you should be running the TC in full router mode.

  • Hildor Level 1 (0 points)

    Here is the NAT setup.

    I do not have the option for a secondary IP range.


    Can you please remove that secondary range and just use the primary.

  • Hildor Level 1 (0 points)

    OK, I have removed the guest network.

    So no improvement??


    You have correctly got the public ip on TC.. and you have NAT setup correctly.. I don't see any particular issues why it wouldn't work.

    please open a terminal and type




    Just copy and paste the result in the thread. eg from mine.

    Unfortunatelly still no improvement. I took the TC to a friends place yesterday just to make sure it was OK and it worked perfectly there.


    Here is the traceroute via the TC:

    TC lacks lots of tools that are common in most routers to see what is going on.. but you are not routing correctly.. I think we have seen this happen before..


    You are getting an different IP on the computer to the TC.. the one of the computer is successful and the one on the TC fails.


    Can you post the full wan details of the TC again as you did above.. and the computer ethernet when they are connected.. I want to see the different gateways subnet masks and gateway (Apple call it routers. )


    And suggest you try manually setting the address in the TC WAN exactly as the computer.


    If you look at the TC it is unable to reach the gateway.. I think this is due to the IP address and the gateway (router) address are not in the same subnet. is the TC address from what you previously quoted.

    The subnet mask is

    But the Router IP (gateway) is

    As far as the TC is concerned it cannot reach the gateway because they are outside the subnet.

    This issue happens with routers connecting via half bridge to pppoa adsl connections.. Windows and Mac OS can cope ok.. But Linux and NetBSD version apple use perhaps cannot.

    In most routers you would fix it manually via the routing table. But TC doesn't really have any such system.


    If you had a pppoe login or something it would work.. but with dhcp it is expecting correctly set values. ISP do not follow that.


    For now you probably will not get over it .. you will need to use a router that can cope with your kind of connection. But ring the ISP and ask them if they have any level 2 support people who could nut out the IP and gateway not in the same subnet.

    I tried to manually set the working address from the Mac into the TC, but it did not work either.


    Here are the latest settings from the TC and the MacBook.

    What you are seeing is the difference between two different OS. The internal  BSD in the TC is behaving correctly.. it is simply taking the values literally and not allowing the TC to route via the supplied gateway. It is outside the subnet mask supplied for WAN interface.


    On the computer you are getting entirely different values.. which confuses me like anything.. !! How come the router address is never the same?? I don't know.

    But if you use a subnet calculator eg

    And plug those numbers in you get exactly the correct value for Router.


    Do the same thing for the TC..

    And the host address range is -


    So a gateway address of 46.236.104.x is hopelessly wrong.


    Without access to the router table in the TC to manually set the packet routing, the TC cannot work with your type of broadband.

    Thanks for your help. I just came back from a longer trip. My ISP has now changed it's setup and everything works fine.
