Notebook mini pcie lan card 天線接駁問題

Notebook - Dell Vestro 1310

原廠用 Boardcom BCM 4312 lan card, 如下圌;駁了1黑,1灰,共2條線
1) 黑線 - 插了 J2, 旁有 AUX 字
2) 灰線1 - 插了 J1, 旁有 MAIN 字
3) 灰線2 - 冇插




新 card : Atheros AR5008
有3個插線頭1,3&2, 請問應該怎樣插?



Thank you!

As your notebook has only 2 antennas, so, you can't connect one of the antenna sockets in your new WiFi card.  And the consequence is, you can have 2T2R but not 3T3R.

Thanks Stephen,

Correct me if I'm wrong, there is a spare cable (grey2) unconnected, can I  making use of this?
In the 2 cable case, what is the correct wiring
eg. black -> 2 & grey ->1
Thanks again!

I really don't know what is the unconnected gray cable in your original case.  Maybe it is not an antenna at all, take your risk.  The black and the other gray cable, it doesn't matter which socket to which cable, it's just one cable should be longer and have a better efficiency, and the other one is shorter or hide under some components.  Your new WiFi card will transmit and receive through the strongest signal antenna anyway.

Good, let's try with the orignal 2 cables.
thanks Stephen!

Tested with multimeter, the resistance of 3 cables are 1.1, 1.1 and 1.0 ohm respectively.
First with 2 cables, everything OK.
3 cables also OK.
Thanks for the advice, thanks again.

Pls have look at the Vestro 1310 service manual

Hi akg,
I was confused with the cable's sequence & priority etc., clarified by Stephen that all cables are the same.
Problem solved, I'm using the computer with the lan card from you.
