OK, I have two Windows machines and maybe a linux box in my office, but the router is in another room. I am not going to run cables. I don't have the time. Anyway the router is a old DI-624 superG. Should I buy 3 G or superG cards? Does superG work in linux? Would superG be worth it over G? What about a wireless G or superG bridge to connect both rooms. That way the internet connection would be wireless, but pc to pc would be wired. Should I move it all to N?
