After you release the dhcp (release/renew) you don’t let the Verizon router get another IP address. You plug the new one into the power first. Then let the Asus boot up and then plug in the ethernet to the WAN port not a LAN port.
you can then look and see if you are up and running.
if there is no DNS simply hit the reset button on the Asus or log into the router and use the routers set up utility.
