Thanks Lippa,
The router is needed because once the coach leaves the driveway, it will be on its own network since it has its own control4 system installed. Also has a cell modem but I am trying to use the homes unlimited internet while its parked in the driveway. I learned the hard way when ATT wireless charged me $200 to download 2 movies in que on the Kaleidescape using the cell modem.
