I want to share my files from one laptop to the other and maybe the desktop. Laptops are according to specs, "wireless". Don't they connect direct wirelessly, without an internet connections? I do not want to share any internet connection or connect anywhere else but inside my house. Just files transfers. Is there a way to do it? Can someone point me where I could read more about this, I shouldn't need a router or whatever, if the laptop is capable of wireless connections, or ??
