thank you. I connected modem to switch. I unplug the power and plug in both the "switch and modem". Now I see the Lennar Wi-Fi ID and I am able to connect Lennar Wi-Fi. I Believe still I am on the half way to complete the set up. My house has three of R510 Unleashed. Each has different LED status. One is green flashing, another is solid green with two amber, third one is green and red ( often changing).
I am googling it to fix
