I've done some searches here and gotten some info, but still not sure. We are moving in to a house that already has a network setup (that I setup) we are moving upstairs it's a large house and we have some devices upstairs that are not wireless also. I would like to add the router we have now to the existing network what do I need to know, and problems/limitations I need to know. We will be sharing a comcast connection and the two routers are these. Connected to Comcast now is Netgear Rangemax WNDR3700 its a dual band router. The one I want to add is the Netgear Rangemax WNDR3400 dual band . (they both should be the same but someone bought the wrong router for us even though they had clear instructions ) Push come to shove we could share the one router, but its a pretty large house and I know signal drops upstairs . Plus we will be sharing 3 windows desktop/laptops, 3 apple laptop/desktops, apple tv, wireless printer, 3 game consoles, Kindle Fire, iPad 3 , 3 iOS devices . So as you can see I would like to break that up a little. Balls after I right that up we all are going to cancer way to much wireless around.
