Few things go further toward making a laptop a productive work tool than wireless Internet access. If you purchased your Dell Inspiron 1300 without built-in wireless, you have the ability to add it through an aftermarket part called a mini-PCI wireless card. Dell designed the Inspiron 1300 so that end users could access the mini-PCI slot without having any technical background or training. Install a wireless card in your Dell Inspiron 1300 to give yourself the ability to access the Internet without a network cable.
Turn the Inspiron 1300 off completely. Disconnect every cable including the power cable, and turn the Inspiron 1300 over so that the bottom faces you.
Push both battery release tabs, then pull the battery out of its compartment.
Remove the three Phillips head screws securing the memory and mini-PCI cover on the bottom of the laptop. The cover is a large flat plastic piece with three screws on one side. Remove the cover and screws and set them aside.
Locate the antenna inside the mini-PCI compartment. The antenna is a thin wire with a small gold-coloured connector on the end. Move it to a location where the wireless card will not cover it, and where you will be able to reach it after installing the card.
Position the card so that the notch in the connectors on the bottom of the card line up with the tab in the metal connectors of the mini-PCI slot. Install the card at a slight angle. Make sure that the connectors on the bottom of the card are fully inserted, then push the top part of the card down until the metal retaining clips snap around the card, locking it in place.
Push the gold-coloured antenna connector onto the "MAIN" port on the wireless card. The "AUX" port is not used.
Replace the plastic cover and three Phillips head screws, then replace the battery and all cables. The wireless card is ready to use.
