I've got a Compaq nc 6230 and want to upgrade the mini-PCI card in it. Right now I've got the Intel(R) PRO/Wireless 2200BG Network Connection and was thinking about upgrading to a card with draft-n capability. I was looking at an Intel card but it seemed to be a different shape than the one I've currently got. It was more rectangular. Will it still fit? I was under the impression that wireless mini-PCI cards were standard. Is it really even worth it to upgrade to N if G is working fine for me?
