The AP does not broadcast the "Configure-Me" SSID always, it only broadcast it when you are configuring the master AP in the network. Once the configuration is done you will not see the Configure-Me ssid.
Seems like the AP might have taken the config. If you have configured the SSID, do you see that name?
If not, you might have to do a factory reset.
Alternately, you can also connect the Laptop to the Ethernet port of the AP and access it on the IP (DHCP IP or default IP 192.168.0.1).
Anyway, I normally thought the lennar r510 APs are configured with some lennar ssid since I bought some r510 from a lennar home builder who got rid of a few since the owners did not want them.
If you are seeing the LED light up on 2.4 and 5ghz.... it is broadcasting a ssid Name of some sort and it’s configured.
Normally if you configure an unleashed AP at default ... the 2..4ghz and 5ghz led would be off even though it’s broadcasting configure me xxxxxx. It’s not until unleashed is configured then the LED for 2.4 and 5ghz is lit up.
Pretty much I believe it’s configured already with a ssid, but you don’t know what’s it’s configured or know the password.
I recommend if you want to do it on your own. Get a ladder and paper clip and use the paper clip to unlock the lock mechanism at the front of the r510 just below the leds which is considered the front. Push the paper clip in the hole to unlatch the r510 and pull it towards the front at the same time and then downward to remove . On the back where the Ethernet cord is plugged in is a reset button and hold it for 10sec.. do it for both.
Note when you do it to each AP, make sure the other AP is unplugged at the switch or the other AP will automatically reconfigure the Reset AP to whatever settings it is configured at right now. After resetting one AP, keep that one unplugged and reset the other one. Once the last AP is reset, just configure it using the configureme-xxxxx ssid. Once that’s done and working. Just plug in the other AP from the switch and it will auto configure it.
Also note, to make sure the AP is reset before you move the ladder from each AP, see if you can see the configure me ssid.
All I can say is the person who came to install your switch did not know what they were doing or just has a specific job in just installing the switch... are you sure Lennar did not give you a ssid to login with password? I think it’s preconfigured already. I’m just not sure what is the standard pre-configuration for Lennar.
