How do I configure my AX to serve as an extender for my AE

Question

How do I get my AE to act as a wifi extender for my AX.  My current home network is a secure network.  My AE has previously been set up to be used as a base station in hotels..1) do I need to reset my AE to use it as an extender?  2) how do I configure my AE to recognize and extend my current secure network?  Thanks

Answer 1

Yes, your Extreme is an 802.11n model as well.
The following is the basic steps to configure both for an extended network:
Dynamic WDS - Extending a Wireless Network Setup
If practical, place the base stations in near proximity to each other during the setup phase. Once done, move them to their desired locations.
Open AirPort Utility, and then, select the base station that will connect to the Internet.
Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
Click AirPort in the toolbar, and then, click Wireless.
Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then, select the “Allow this network to be extended” checkbox.
Next, select the base station that will extend this network, and then, choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then, choose the network you want to extend from the Network Name pop-up menu.
Enter the base station network and base station password if necessary.
Click Update to update the base station with new network settings.
