You would not want to setup the AX-N to "join". It provides no wireless coverage at all in that setting.
Here is how your settings should look on the AX-N:
Open AirPort Utility - Click Manual Setup
Click the Wireless tab below the row of icons
Wireless Mode = Create a wireless network
Wireless Network Name = Same name as your "main" network if you want the new AX-N to act as if it were part of the same network. Otherwise, assign a different wireless network name (which will require that you log on to the AX-N network separately)
Radio Mode = 802.11n (802.11b/g compatible) a good choice
Channel = Automatic
Wireless Security = Exact same setting as your "main" network
Wireless Password = Same password as your "main" network
Confirm Password
Click the Internet icon
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)......(you may be a bit surprised to see that the AX-N was likely not in bridge mode as you thought)
Update to save settings and allow 40-45 seconds for the AX-N to restart
You should have a green light
Then, power down the entire network....all devices....order is not important
Power up the modem first and let it run a few moments
Power up the "main" AX next and let it run a minute
Power up the "remote AX" next the same way
Power up the AX-N the same way
Power up other devices one at a time the same way
You should have one large wireless network if you chose to assign the same wireless network name to the AX-N device.
