Your ISP's DHCP is not functioning properly

My xb6 modem in bridge mode power cycled yesterday and now will not connect to my router. I've tried everything. It's been power cycled so many times.

My asus router gives this error
Your ISP's DHCP is not functioning properly
and from reading several threads here it seems I need a provisioning signal from Comcast and that @ComcastChe is the person to help.

Can't be without internet during these work/school from home times!
