I don't want to add any extra security measures. I don't want to make it more complicated plus no one could really gain access to anything unless they are in our house... no one lives close enough to access the router plus there won't be much if any critical information being done. But Help me clarify this whole IP thing. Will the new router which will kind of serve as an access point just give new IP's to every computer it's connected to through wireless. Is this the same for the things I plug into the remaining three Ethernet ports on the back?
