Can someone help a stoopid person (that would be me). Tell me if I understand how a router works before I go buy one. This is what I want to be able to do. I have a desktop at home and also use my laptop from work. If I get a router, can I plug the router into the black box modom, then plug both my desktop and laptop LAN cables into the router and be able to be on the internet on BOTH computers at the same time? Or is that not what a router does? Basically, I want to be on my desktop for the running PBP's of Worlds, but also need to be on my laptop at the same time for work and need an internet connection for that also. Will a router do this?
