DCHP did not function properly.

I have a brand new Asus GT AX11000, after all the initial setup ran into message, DCHP did not function properly. However if i connect to the modem (Netgear CM1200) everything seem fine. I did perform reset the modem and even use the web site to send restart the modem and nothing work.

I read on the forum seem like having some one from Xfinity send a provision signal might solve the issue.
