Time Capsule Base via ethernet to an Airport Extreme to extend Wireless

Question

I have set up a new Time Capsule dual band (TCBStn) as a base station (connected to the internet). I want to connect a new Airport Extreme dual band in a family room far away from the base via Ethernet. This family room has an Apple TV to which I want to stream video. I am not able to connect the AE via the Airport Utility as the Airport Utility does nor recognize the AE.

Answer 1

My recommendation is to configure your two base station as a "roaming" network. This will allow wired/wireless clients to connect to either and still be able to "see" each other for sharing.
Please start by powering-down all of your network components as follows:
o Power-down the modem, Time Capsule (TC), AirPort Extreme Base Station (AEBS), Apple TV (ATV), and the iMac. Note: The power-down order is not critical.
o With all of these components powered down, disconnect both the TC & AEBSn from the network, and then, perform a "factory default" reset on both to get them back to their "out-of-the-box" configuration.
o After both have been reset, remove them from power, and then, reconnect them as follows: modem > \[WAN port] > TC > \[LAN port] > \[WAN port] AEBSn, where ">" represents an Ethernet connection.
o Power-on the modem; wait at least 10-15 minutes.
o Power-on the TC; wait at least 5-10 minutes.
o Power-on the AEBSn; wait at least 5-10 minutes.
o Power-on the iMac.
o For now, leave the ATV powered-off.
In this configuration, both routers will be transmitting their own wireless network, each having a Network Name of something like: Apple Network NNNNNN, where the Ns represent the last six digits of their respective AirPort IDs.
Now, from the iMac, use the AirPort Utility (in Manual Setup) to access the TC to make the following configuration changes:
o Time Capsule > Base Station > Time Capsule Name = TC
o Time Capsule > Wireless > Wireless Mode = Create a wireless network
o Time Capsule > Wireless > Wireless Network Name = <enter the desired Network Name>
o Time Capsule > Wireless > Radio Channel Selection = Automatic
o Internet > Internet Connection > Connect Sharing = Share a public IP address
o Leave all the other default settings (for now).
o Click on Update to write the new configuration to the TC.
While still in the AirPort Utility, select the AEBSn, and then, make the following changes:
o AirPort > Base Station > AirPort Extreme Name = AEBSn
o AirPort > Wireless > Wireless Mode = Create a wireless network
o AirPort > Wireless > Wireless Network Name = <use the same Network Name that you created for the TC>
o AirPort > Wireless > Radio Channel Selection = Automatic
o Internet > Internet Connection > Connect Sharing = Off (Bridge Mode)
o Leave all the other default settings (for now).
o Click on Update to write the new configuration to the AEBSn.
You should now have a basic roaming network. Verify that your iMac can access the Internet while connected to either base station by wire or wireless. Please post back your results.
