I am trying to create a file sharing network between a wireless desktop and hardwired laptop. Also later I may want to add another wireless laptop. I have given both computers the same workgroup name and run the windows home network wizard but I cannot connect to either computer. Neither one seems to recognize the other. I have heard some people talk about switches. If this is what I need to fix it please explain to me what a switch is and how hard it is going to be to set one up.
