Hello everyone
I want to upgrade my current Intel 3945 to Intel 4965 but I know the new Intel 4965 have 3 antenna and the old Intel 3945 only has 2 antenna. I was wondering where I can get antenna that is made for laptop. I plan to just run it around the edge of my laptop. I know some people said it works fine with just 2 antenna but I have a wireless N router (D-Link DIR-655) and I really want to make good use of the wireless N speed.
Thank You in Advance.

It's not a antenna, it's just card to plug in to a pci-e slot.

yeah but there's three wires that plug into the card for the antennas. i don't know where to get them, but mine has a white,grey, and black wire.
-
Yeah, I've been looking everywhere for them. I want to get it before I get the PCI-E slot card.

E-bay is your best bet to get one.
I just put a wireless N card in a T60P Thinkpad and had to install the 3rd antenna.I put it under the palm rest and it's working fine.Getting the full 300 speed.
The antenna is cheap on e-bay.$5 or $8 bucks. -
Which antenna did you end up putting underneath the palmrest? I see a couple different ones for sale. Big and flat, or small and thin?
-
OxfordTec have the antenna's and ship world wide, and accept paypal.
Going to the i4965 is not going to give you the best upgrade.
i4965 only does 130Mbps max @ 2,4hhz, 5Ghz band will give 300Mbps but you also need a 11n 5Ghz router. -
The 4965 will work with only 2 antennas connected, you don't need all three.
With only the main and aux antennas connected you won't get full 300Mbps, but you can still connect at lower tier draft N speeds. I was able to connect at 130-150Mbps using my 4965 and only 2 antennas connected. -
In response, yes, I am fully aware that I need a) a 5GHz router (I do), b) MIMO support on said 5GHz router (I do) c) at least a 4965 (I have a 5300 on order).
So. Wondering if anybody has dBi numbers for those big flat antennas? I saw that the little thin ones are billed at 3dBi on oxfordtec's website. I'm thinking I might have some issues finding a place for even something that thin. I'm probably going to take apart my laptop to some extent, and put the antenna in the screen casing. -
Hello,
I also have a laptop with 3945 mini pci card in it, and it has 2 anntenne connections. WOuld like to upgrade to 4965agn. Also have a dlink dir 655.
1. I;m wondering the anntenne has the numbers 1 2 and 3, what to connect where?
2. ANd did people sucseed doing this and working with this router?
Looking forward what I should do. -
As far as I know, intel 4965 + DIR-655 will give you only 130Mbps maximum.
On 4965 there are 3 connectors
white wire is MAIN (1) , black is AUX (2), gray is 3rd
First 2 are important here, 3rd one is using on 5GHz operation and extra range as far as I know. You don't need that if DIR-655 is your router; performance will be roughly same w/ 3rd antenna or w/o 3rd antenna. -
The 3rd antenna is used for receiving only as the i4965 = 2T/3R
-
Oh thanks for the info! So that's going to be the same as 5100, right? And is 5300 3T/3R??
Wonder if it shows extra throughput in real life?
-
The i5100 = 1T/2R so in reality can only send data to the router @ 150Mbps but receive at 300Mbps, although I think it will only work at 150Mbps both ways.
Yes the i5300 = 3R/3T and can do up to 450Mbps using all 3 antenna's BUT there is no 3 channel routers out there yet to get the 450Mbps
Using only 2 antenna's will still get you 300Mbps but of course less range.
Done a wee write up in the post below this one, that explains things on a heap of cards.
