I'm currently using a timecapsule to extend my existing network and provide a second wireless network. Myrouter, acting as my DHCP server, is a Netgear DGN3500.

My TC is connected via Ethernetto this, and is creating it's own wireless network.

I'm noticing a problem wherethe TC is not handing out IP addresses - my iMac is saying "Self-assignedIP address" or "No IP address" and thus unable to connect to theinternet via the TC, but can work fine via the Netgear router. Similarly, myphone is often unable to connect to the TC due to not getting an IP address.The problem can usually be fixed, temporarily, by simply restarting the TC –although this is hardly a permanent solution.

There is a windows PC wired viaEthernet to the TC, which works fine on the internet and network.

 

Am I missing a setting somewhere?

    If  you have the TC connected to the Netgear router, make sure that it is configured in Bridge Mode to allow the Netgear to provide IP addresses for the entire network.

     

    Open AirPort Utility - Click Manual Setup

    Click the Internet icon

    Connect Using = Ethernet

    Connection Sharing = Off (Bridge Mode)

    Update to save changes

     

    Restart your entire network

    I have a feeling that the TC is only assigning a single IP adress wirelessly - is there any way to fix this?

    The TC is not assigning IP addresses if you have it configured correctly in Bridge Mode. That is the job of your Netgear router.

    Please double check to make sure that the TC is setup in Bridge Mode, as what you are experiencing indicates that it may not be.

     

    AirPort Utility - Manual Setup

    Click the Internet icon

    Connect Using = Ethernet

    Connection Sharing = Off (Bridge Mode)

    Update to save settings on the TC

     

    Restart the entire network

     

    If this does not help, I am out of ideas. I haven't worked with Netgear is some time and cannot remember much about the setup of the device. It is definitely up to the Netgear to provide IP addresses to any clients that connect to the TC, since the TC is in Bridge Mode.

    If the wireless devcies are not working, but the wired connection is working......

     

    Then this starts to look more like a situation where you are picking up wireless interference.

     

    Typically, when you restart a router, it "looks" for the best available channel to use. But, if other folks around you start using their wireless network, cordless phones, wireless security/camera systems, then things can get overcrowded and you lose your connection due to the interference.

    The Netgear and TC may be interfering with each other. The only way to find out is temporarily turn off the wireless on the Netgear router, use the wireless only on the TC for the test,  and try that for awhile to see what happens.

     

    I'm out of ideas after that.

    I'm begining to think there may be some kind of fault with the TC, or am I jumping to conclusions in thinking that?

     

    I suppose that anything is possible, but since the TC acts as a "pass through" device to allow the Netgear to provide DHCP and NAT services to all devices, there is a lot more going on here than a simple association between just the TC and other wireless devices.

     

    I'm afraid that all you can do is take the TC in to an Apple store to have them check the device, but you already know what will likely happen....the TC will perform perfectly there.

     

    I can't explain why it would happen because two devices configured correctly should work together....but there are sometimes situations where two devices that work correctly by themselves do not work correctly when they get together.

     

    The TC was designed to connect to a simple cable modem or DSL "bridge modem". It will usually work with another router or gateway, but it's not possible to say whether it will always work with another router or gateway.

    I have recently encountered the same issue, only my configuration is my TC is connected directly to the cable modem and I use the TC as the hub for my wireless network.  My MacBook can connect wirelessly to the TC and out to the internet.  However, my iPhone or iPad will no longer connect. Anyone have any ideas?
