Hi donlavaughn. Welcome to Flyertalk and thanks for the useful info! Interesting that the router locks everyone out - even the tech. I suppose you have to reset it to factory to get back in? How does the control pad thingy that talks to the router know what wifi network to connect to? I'm assuming there's some hidden network setup menu in there?
In any case, I did put the Comcast router behind the main house router. We don't have any cameras so it doesn't matter. Thanks.
