Connect the appropriate antenna cables to the

If the WLAN card has two triangles on the label (white and black),
connect the white antenna cable to the connector labeled "main" (white
triangle), and connect the black antenna cable to the connector labeled
"aux" (black triangle).
If the WLAN card has three triangles on the label (white, black, and gray),

the gray triangle.
