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.
