We had tenants as the first people in our lennar home with the 7150 switch and a single AP. We moved parents in after old tenants left but we never got the wi-fi password and it looks like switch password was set by either then or lennar. What’s going to be the best way to reset so i can get the ap going so i can. put the xfinity router into gateway mode and just use the ap?
If you don't know the username password of the Unleashed web console then you have to factory reset the AP.
I am assuming you have R510 AP being a Lennar home owner, findout the tiny hole near the ethernet port on AP and push the button with a paper clip. Now hold the reset button for 12 seconds and then release it.
Doing above will factory reset the AP and then you can re-setup it either by connecting configure.me WLAN/SSID or connect a laptop to one of the switch ports available on your ICX7150 and then try to access "unleased.ruckuswireless.com" this will allow you to setup the AP again and set new admin password and network.
