    Dell Latitude E5400 - upgrade wireless

    We have several of these laptops, which I believe only have b/g wireless. Is it possible to do a firmware update to make them wireless 'n' ?
    Thanks in advance!

    Depends what card you're running in them.

    Any idea what card you're running?

    The standard Dell 1397 card is G only - this is in hardware so would need to be physically upgraded if that's what you've got. The other wireless options on these models support N.

    It's will either be a PCI-E or Mini PCI card. find out whicha nd buy a bunch of something similar of Ebay.

    You may find that some cards use 3-wire antenna but the laptop may actualy have 3 wire in it depending on it's age. I can't remember if you actualy need the 3rd wire or not.
