I have installed a netgear wireless router at home & connected two PC's through cable & one laptop via wireless connection. And
Its very easy to connect my wireless connection & see & visit files & folders of computers connected in network from a laptop or some wireless connection. And I am not able to track it.
So is there any way to share my files with only those computers which I want or they have some permission to access them or can i create some user name or password thing to access files or computers.
