yes the actiontec is required for the FiosTV service. with out it the IPG (Interactive Programming Guide) can not recieve updates nor will your VOD (Video On Demand) service function or the widgets.
You can get another router and piggy back it off the action tec and use ur router for wireless. just make sure it doesnt have the same ip as the actiontec which is 192.168.1.1 maybe change your router to 192.168.2.1
yeah i'm gonna do some research into other MOCA enabled routers and start a topic about it
we get this question alot.
