Help with Extender/Router setup

Plemans,

I did a factory refresh on the router and the extender in the garage. I set the extender up as an access point since it is "hardwired" to the router through a fiber cable underground.  I believe that is better than setting it up as a wifi extender.

Everything looks ok. To make sure I understand this correctly - when I am in the house, my laptop connects to the router and displayed as a wireless connection in "attached devices".  However, when I take my laptop in the detached garage (and my phone), they should connect to the access point out there since it is a stronger signal.  BUT when I am logged into the ROUTER, and look at "attached devices", both the laptop and the phone are showing as "wired" connection, even though they are clearly not.  I assume that is because the laptop and the phone, even though wirelessly connected to the access point, "appear" to the router as wired - since their traffic is coming through the fiber cable to the router.  I have that correct?

I have not messed with the other extender yet.  I moved my Sonos Boost to a hardwired connection on the router, so technically I don't need this extender anymore.  Correction - I have an old HP Laserjet 4P printer (circa 1994) that I love that does not have wifi so I have a parallel port print server (StarTech.com PM1115P2) connected to the printer.  This was connected to the extender upstairs along with the Sonos.  But now I run the ethernet cable right to the printer adapter and bypass the extender.
