I have two EAP225 outdoor units.  One is hard wired into my ethernet network and works fine on its own.  I want to install the 2nd unit in an out building as a wifi extender, so it will not be wired into the network.

I assume that means I need to run the two as a mesh network, is that correct?  Also, I downloaded the Omada Software Controller but it seems to do nothing.  When I run the .exe that was downloaded, it installs some items in a folder, but none of those items is an executable.  Do I need a hardware controller as well?  Or am I doing something wrong with the installation.
