I am trying to extend my WiFi throughout my property and have bought 2 different EAP610 Access Points (both shown below).   I first installed the Outdoor unit and then wanted to add more signal inside a shed.  I ordered the ultra-slim thinking I should be able to set it up to repeat off the Outdoor.  But even though they are the same model with almost the same description, the Ultra-Slim only seems to work via LAN cable - not as a Mesh repeater?

Am I missing something here?  I looked for a firmware update and there isn't one.  But there doesn't seem to be anyway to configure the ultra-slim to pick up the WiFi siignal from the Outdoor and use that?

I'm just surprised that given these are both EAP610 AX1800 - they have very different configuration menus???

Any help would be appreciated.
