I just upgrade my Arris sb6183 to sb8200 because of 500 mbs Mediacom service and have auto dhcp problem.
When i reset the power on arris sb8200 modem and Netgear r7800 ddwrt router at the same time i am loosing Internet on router and there is no IP received from Mediacom just 0.0.0.0.
I am connecting my win7 PC directly to modem and its receiving dhcp IP right away and i am able then to connect back my router to modem and it works.
What can be a problem? I am very confused because it works absolutely stable on sb6183
