That is very very interesting!
I really like the way my Netgear router works, its private and when I set it up, there were many things to do. I really didnt know about routers, but I see I better learn a bit more, since you warned us about Comcast.
Im going to run this by a friend who writes a tech column in our local paper once a month, he seems to know a lot more about Comcast, then they know about themselves.
I will let us know what he says, it might be a while, as he goes home to Australia frequently with family.
