Need assistance with solving the ipv4/ipv6 issue (i.e., only some websites are accessible, for example, google, youtube and netflix).

I have Arris SBG6782-AC.
After spending two hours with tech support and motorola support line, I finally found the thread above who suggests @ComcastJohnN may be the one to reach out since he knows what needs to be fixed.
@ComcastJohnN, if you read this, please contact us back when you get a chance (firstname.lastname@example.org)
