My brother found a 3Com Fast Ethernet 10/100 Base-TX PC Card at his workplace, with no manuals or anything. Recently, I bought a Dell Inspiron 1200 with no wireless card, and I am trying to figure out if this PC card he found is of any use to me. I was thinking of buying a wireless card (I don't know the proper industry name) so I could use my notebook wirelessly just as he does. I'd like to know if this PC card can help me accomplish this. To be honest, I don't know the difference between NIC (Network Interface Cards) and wireless cards. I popped this PC card into my notebook, and XP detected it. However, I dont know where to go from there. I am guessing I have to do more than simply putting the card in....installing drivers, changing settings, etc. If this PC card will do the job for me, I won't have to buy a wireless card. My brother has a Dell Inspiron 1150 and it came with a wireless card. Therefore, he didn't have to install anything to use the Internet wirelessly.
