Instructions for installing a wifi card in a Dell desktop.  Some features may appear slightly different depending on the computer’s model or the wifi card’s model. To remove one, simply reverse the instructions.

 Instructions

• If antenna(s) is/are attached to the card, unscrew them. You may need to install the backplate.  If so, orient it so that the bent portion is opposite the “teeth” of the card, as shown.

• Locate the latch for the computer. Open it and remove the door. Optiplex 5050 is pictured.  Latch may vary for different models.

• Locate the latch that locks the PCe cards in place and open it.

• Remove the filler plate (if present).  It may be a grating, as pictured, or solid.  It can be a semi-permanent piece that will need to be snapped out, or it may be a fully removable piece as shown.

• Insert the card, with the “teeth” fitting into the slots on the motherboard, and the backplate fitting where the filler plate was.  It should click into place without much effort, and the backplate should fit nearly flush, just as the filler plate did. The “teeth” should fit down into the slots so that the metal on them pretty much disappears into the slots.

• Close the latch to lock the PCe cards in place.

• Connect (or reconnect) the antenna(s).

• Set the lid back onto the frame and slide it into place until it locks.
