Need instructions for replacing or upgrading the internal wireless card on an Asus M2400N notebook? Here it is. With this guide you’ll be able to remove the notebook keyboard and get down to the wireless card slot.

I used an Atheros Cardbus card for a while, using the madwifi driver, but the laptop has only one PCMCIA slot, and it was a bit of a pain to have it always occupied.

Now I have bought an Intel PRO/Wireless 2200BG mini-pci card, which I managed to insert into the laptop with not too much difficulty.

Instructions for replacing the old wireless card:
1. Unsnap the antenna cable from the wireless card with your fingers. Do not use plyers, use fingers or you can damage the connector.
2. Spread the latches on both sides of the card. The wireless card will pop up at a 30 degree angle.
3. Carefully pull the wireless card from the slot by the card edges. Do not touch chips on the card.
4. Insert a new wireless card and connect the antenna cable. There are two connectors on the card - Main and Auxiliary. Snap the antenna cable on the main connector.
