No IPv4, only IPv6 (Arris SBG7580)



I am having what seems to be the rather common issue of having No IPv4, only IPv6 with my Arris SBG7580, despite several service calls and a tech being out here. Comcast says my issue is needing Arris to change modem settings, and Arris says Comcast isn’t dual provisioning my router. Any help would be greatly appreciated.

Good luck !
