I have just bought a new laptop that has a wireless NIC, as I plan to use it when I'm not sitting at my computer desk. I would like to add it to my network so that I can access my other computers from it to share files, as well as to connect to the internet. Right now, my other 3 computers, which are all in the same room, are connected through a hub and then a router (all by cable). The router that I'm currently using only has 2 ports, one for cable in and one for cable out. The setup I am using is: -> modem -> wired router -> hub -> computer1, computer2, etc. If I replaced my router with a wireless one and connected all of my computers to the ports on it (whether with cable or wireless), would I still be able to share files between them, or would they only have a shared internet connection? If not, how would I go about doing it?
