Nigh on to impossible
I was looking to go with a 108g NIC replacement for my 8104 and 8204 laptops. I went so far as to purchase 2 from a dealer on Ebay thinking the interface was mini PCI. After opening up the machines I found out that the connector is about half the width of mini PCI, Alas, the card ACER uses is PROPRIETARY. I called ACER support to find out if a card was available from them, or their supplier, and they said only at the repair level could a new card be obtained, AND only 54g was available. This was about 3 weeks ago, so I doubt if it has changed any. Luckily, I had an understanding dealer and was able to send back the mini PCI cards that I had purchsed. Good luck in YOUR quest.........I have retired!!!
