Putting Your Network Card in Your Computer Locate an available slot for the card. Determine the correct orientation of the card for inserting it into the slot. If you are putting the card into a desktop computer, be sure to ground yourself before you handle the card.
Static electricity can damage the card.
Push the card gently, but firmly, all the way into the slot. Connect the pigtail, network cable adapter, or network cable to the card. Be very careful with this step. Connect the network cable to the network port. A telephone cable will NOT work.
