A:Answer I am not famkliar with Optimim but it seems to be TV over Wi Fi. If what you want is IPTV, then any internet service you hire from a major provider (like Comcast), should give you access.
The Arris Surfboard 6900 is a cable modem and a router in one box. It works great. You can use it with Comcast. You can service any Wi Fi capable equipment, but the speed you buy will be crucial. The more, the better.
