Only One Site Blocked During Wireless

I have a Netgear Nighthawk AC wireless router. I am connecting my Alienware 15 with "Killer Wireless". When I am connected via Ethernet I can access login.live.com, but when I go into wireless it shows a blank page instead of login.live.com; this is Microsofts main login page so it's a huge problem.

If I use any other router with the Alienware I can reach the page. If I use any other PC with the that router Incan reach rhe page. Only this laptop when combined with the router on wireless does it cause the problems.
