Connecting my 15000 to wifi

AUDREY <Contessa@...>

I set up my 15000 last night, so that it was wifi enabled. I have the black wifi sign in the top right of my screen.My 15000 is switched on and just about 4 feet from the router/PC.
Just went to the Emblink Tool in Horizon Link. Clicked the top left button - Connection Settings - clicked wifi button and search.
I just keep getting a message that says "No machine found"
Can anyone help me please?
Thanks so much.
