Do I need the 3rd antenna for "N" on my Intel 6300

I just put an Intel 6300 in my Asus G73JH which only has 2 antennas. I thought the 3rd antenna was only for acheiving 450mbps. When I connect to my router, I'm only getting "G" 54mbps.

I went to configure the network adapter and it only shows up a/b/g.

I got the newest drivers from Intel's wesbite.

Any thoughts?

Thanks.

 

I believe so, yes.

Edit: I could be wrong though, but I believe I read somewhere that for the best Wireless N performance you should have that third antenna. Maybe I'm thinking of MIMO or something.

 

You need to use WPA2 +AES as security in order to achieve 802.11n speeds.
It should work at least @150mbps (if not @300mbps) with only two antennas

 

You can get 300mbs with two antennas, your close enough to the router and you hold your tongue just right. For three, I would have to kill my two year warranty to remove tamper sticker to pull my laptop apart. No thanks. A solid 54mbps, with no drops, is fine unless you have the need for HD video streaming.

I find keeping a solid 300mbs a challenge so maybe the third antenna, set up properly would help?

 

You know.. I have often thought of security settings overhead but find the manuals sorely lacking in this kind of info

A chart showing WPA2 +AES vs all the rest would be asking tooo much from the vendors?

 

You can find a comparison of how the security affects throughput on smallnetbuilder (somewhere) but that wasn't my point- 802.11n requires WPA2 to run- it's just part of it so if you have great signal, n router and n adapter and choose WEP or WPA you won't get above 54mbps.

 

OK, thanks.

I re-read my installer help screens and there is a sentence that reads just like your post. Dumb luck, I picked the right one. There is a review on smallnetbuilder on my router so I'm off to see what else i missed.

Did the OP find his problem yet?
