2. Connect the antenna cables to the antenna connectors on the WLAN card by matching the color of the cable to the color of the triangle beside the connector. Connect the main antenna cable (white) to the antenna connector with the white triangle. Connect the auxiliary antenna cable (black) to the antenna connector with the black triangle.
   
   

NOTE: Your WLAN card may have two or three antenna connectors, depending on the type of card you ordered. If your computer has a gray antenna cable, attach it to the connector with the gray triangle, if one is available on your card.
