I have a Linksys Router EA6400
It connected just fine with a Sony Smart TV, a Cannon Wi-fi Printer, 2 laptops, 1 Dell and the other Gateway and a tablet.
We just got 3 Nokia Lumia 635 window phones for the kids and none of them is able to connect. They can find the Wi-fi but do not connect.
Phones do conect in the library, at wendys' etc. but not at home. Any ideas....
Thanks
