I have a 2TB Time Capsule (4th Gen) and a newer Airport Express (MC414LL/A).  I use the Airport Express to extend my wifi coverage, however, the download speeds are significantly reduced.  As a result, I want to creat a Roaming Network by linking the two with an ethernet cable.  Seems easy enough, but every time I plug in the ethernet cord, I get disconnected from the internet (on Airport Utility 6.1, it shows "yellow" lights on the "Internet", "Time Capsule", and "Airport Express"). By just unplugging one end of the ethernet cable (from the Time Capsule is nearest) seems to restore the internet again.  The Time Capsule Router Mode is set to "DHCP and NAT" and Network Mode is "Create a wireless network".  The Router Mode on the Airport Express is blocked out, but shows "Off (Bridge Mode)", and the Network Mode is "Extend a wireless network".


Please help!

Airport Express, Mac OS X (10.7.5)

    I'm not sure I have straight what you are doing. You have a Time Capsule functioning as your router. You have an Airport Express that will be located remote from the Time Capsule. The AEX is to extend the wireless network. I would begin with having the Time Capsule set up as your router and connected with Ethernet cable to your modem. Plug the AEX in somewhere close by. With a toothpick push in the reset button on the AEX and hold it down until the status light starts blinking rapidly. Open Airport Utility. One the AEX light starts its slow blinking you should see it in Airport Utility. You want to configure the wireless network to Extend an Existing Network, then select the network you want to extend. Enter the name of the network and the login password for the Time Capsule. Configure the protocols on both devices so they are identical. Save the configurations of both devices. The AEX status light will turn green after it restarts. Unplug the AEX and take it to its remote location and plug it in.


    This configuraion does not require connecting the AEX to the Time Capsule with Ethernet cable.

    You won't change anything by what you propose because the AEX will still be running at the wireless' maximum speed. All you do is make the transfer between the Time Capsule and the AEX' Ethernet port run at Ethernet speed. Your wireless will not be any faster.


    Why do you need the AEX since the Time Capsule provides its own wireless? How slow is the wireless you now use? How old is your AEX? Do you have the devices configured correcly?

    Depending on the configuration wireless may be around 240 Mb/s down which is a little less than 20% of your service speed. So, I don't see where the wireless is slower than expected.


    Here's my info. I have an older AEX:

    Internet panel is configured for DHCP in the dropdown menu.


    Wireless is configured as:

    My Network Mode is to Join a wireless network, while yours should be Extend a wireless network. You will then have another panel titled Internet.


    And, AirPlay:

    I cannot show you the AEBS setup because I'm not using one. Mine is a third-party device.

    If you mis-configured the Time Capsule then perhaps it wouldn't hurt to reset it to factory defaults. On the rear of the Time Capsule you should find a small reset button that is flush with or recessed a little witht he case. Use a toothpick to push the button in and hold it in until the status light starts blinking rapidly. Now do the same with your AEX. The devices need to be plugged in for a reset.


    Then reconfigure the Time Capsule for your normal use being sure you don't make the mistakes you originally made, whatever those were. After which do the same with the AEX.


    Perhaps starting from scratch will resolve things.

    No, just the network configuration. See the following: How to reset Time Capsule.

    To what are you connecting the Ethernet cable to? It must be connected to an Internet ISP source. Same source you use for the Time Capsule. If you are connecting it to one of the LAN ports on the back of the Time Capsule, then you can only get it to work, if at all, is to put in an outside DNS address like in the TCP configuration of the AEX.

    Having read this thread through carefully, it appears that some important items are being overlooked. 


    Namely....the Express has been configured to connect using wireless only....and then an Ethernet connection is introduced.....which is a sure recipe for a network crash.


    I would suggest that you power off the AirPort Express for now and make sure that the Time Capsule is operating correctly. 


    Once that is confirmed, the Express needs a "hard reset" and a proper setup needs to be followed to configure Express the way that you want.


    If you want to pursue this, we can provide the steps to configure the Express correctly. The setup is much easier than you might imagine.  Post back if you would like to try a different approach.
