Bridge mode not working after Cox upgraded SBG6850 firmware to Arris this week

How can i get my asus router to pull a WAN DHCP ip from the SBG6850 after cox swapped my modem firmware to this arris version?

They broke me, I cannot get bridge mode to work any longer.  "Your ISP's DHCP function is broken."

I have tried everything:

Aggressive/normal DHCP mode.

spoof LAN TLL

extend WAN ttl

Mac clone of asus mac on SBG6850

Mac clone of SBg6850 on Asus router

undo everything

redo everything

reset modem

reset router

The dam Cable modem wont give the router an IP address after this Arris firmware ** update.  How to Fix?
