    Hello
    I'm looking to upgrade a laptop's wifi card, the current card has two antennas (Black and white). I want to add an "N" Card It has 3 Antenna Connector's.

    Is this just for better reception?
    Should I just add A Third Wire?
    Will that be ok?


    Thank you

    1. 2 vs. 3, it really doesn't mater.

    'n' wireless cards use a third antenna for antenna diversity. i.e. they take a look at the signals and ignore the antenna with the worst signal. So they don't actually use 3 antennas.

    Should I just add A Third Wire?

    2. You can't unless your card supports it.

    Will that be ok?

    3. Adding a third antenna? I don't see how you would do it if the card doesn't support it.

    Thank you I didn't Know that's how they worked.

    To clear things up:

    My card right now has two antennas.
    The card I'm buying Takes three antennas.

    I'm Replacing the top of my PC and front Benzal So I might as
    well just Buy and add a third antenna while it's open.

    I'm guessing the wire's are the same I Don't know why there different colors.

    Thank you
    Very Much
    I couldn't find any info on this anywhere.

    Most cards come with antennae.

    Why are you "adding" a new antenna? (unless you are replacing the stock antenna with an extension.
