I have a Sony Vaio and whenever I get a couple feet away from the router the wifi stops working and cannot connect, I've had this computer and router for a while and this has never been a problem.
EDIT: I don't think it is a router or internet problem because other devices (phones, ipads,laptops,desktops etc) work.
