Haha. You can't change your ip back to a 12. ip address. Once they set the routers scope, that's it. You will not get that 12. back.

Sorry Happy but
I got my 12. ip address back and now things are normal. Everything is working again. Now I can use my Sipphone to call Mediacom support and complain about the slow speeds, outages, etc.
BTW "Smac 2." looks like an interesting program. I am going to check it out.
