I am having the same issue, can only get an IPv6 address on my new modem. Got a new Motorola MB7420 after my other modem blew up in a storm. Phone support is useless, they say the modem is online but web access is not working and in the modem I can see I am only getting an IPv6 address. Everyone says to message @ComcastJohnN or @ComcastChe but I can not seem to send private messages. @ComcastJohnN or @ComcastChe can you please help? I am desperate!
