I can see after only a few hours how having a router in the boat is going to make things nicer for me, and my children, not to mention my wife. Everything get connected to the boat system wirelessly. A wireless printer can print and if there is a free internet access point anything can be downloaded or streamed. Even if there in no internet with cellular data things can be streamed ( at a cost to data plans) to the individual devise and shared. I'm a troglodyte so I'm sure I'm missing some important downside things like the CIA can now track me.. WTFDIC
