Comcast just had my upgrade to a router / modem in 1 with my new X1. I have always created a wireless network with my Apple Time Capsule which i really like. Now with the comcast router it creates a new wireless network. I would rathe keep my current wireless settings which work as well.. Is it necessary that i put the comcast router in bridge mode? Is there harm is having 2 wireless networks, like am i sacrificing speed of my time capsule network because the comcast router is making a network too.
