Intel wireless wiifi link 4965AGN Sony white Gray Black wires??

Hi,

I have a Sony VGN-NR498E with an Intel Wireless Wifi Link 4965AGN MM1 installed.

I recently had to replace my LCD screen (myself) but forgot the order of the antennas.

From left to right it's labeled 1, 3, 2 and the colors of the connectors (wires) are Black, White, and Gray.

How should I connect the correct color connect to the correct label? it will also be helpful if you can provide a source (link).

Thank you in advance,

 

1 - Grey
2 - Black
3 - White

 

Hi lindanbobby,

Thanks for the reply.

The reason I asked for a link was because I found places on various websites with different results.

For example:

1. http://home.comcast.net/~nw_systems/vgnN.pdf

Page 11, connector 1: black connector 2: gray

2. http://www.notebookcheck.net/typo3temp/pics/3d45304ccc.jpg

connector 1: black connector 2: gray connector 3: white

3. http://computershopper.com/feature/build-your-own-laptop-assembling-your-laptop-parts

this is what they state:

"Connect the black wire to connector 1, the gray wire to connector 2, and the white wire to connector 3."


So you see the web is full of different results. So it would be helpful if a sony vaio user with that same wifi card can verify and more helpful if you can point me to a source.

Again thank you, not that I don't trust you, it's just that too many different answers out there.

Thanks.

 

Hi Kuajfas ,

Thanks for the reply.

RDMS? Do you mean relational databases management services? I really don't see how that has to do with my issue. Please elaborate and post a related link.


Thanks

 

Grey is supposed to be the center (#3), while white is normally #1 and black is normally #2. But the last two wouldn't hurt if reversed, because they are just left and right antennas installed on laptop's LCD frame. Which is left and which is right depend on from where you see the laptop. Actually, if you mixed up all the 3 antennas, as long as they are all connected, you can still have wireless connections.

 

Hi aidil,

Appreciate the reply. I read on other sites order doesn't matter, its not like its power and ground or transmit and receive, so thanks for the reassurance of if I mess up nothing will get fry and I will still get wireless connectivity.

However, for the sake of getting it correct so I won't have to re-open my laptop and I also read that for MIMO (the technology that uses the noise constructively and not try to cancel the noise) order matters because it creates a fourth antenna. I don't know if my card have mimo but who knows what stuff goes on we are not aware of.

Please if anyone who is certain of the configuration or point me to a valid source or somewhere I can read up on it. I have tried intel and sony's website but no avail.


Thanks everyone.

 

In MIMO terms, radio signals transmitted from each antennas of the wireless router would travel in the air and would bounce of materials before they each reach the laptop's antennas, vice versa. So, it's not like you can precisely instruct those downlink radio signals from router's antenna #1 to be the first arrived at laptop's antenna #1 and consequently for the 2nd and 3rd (vice versa for the uplink radio signals). With bounces and many different positions of both router and especially the laptop since it's a mobile one, any radio signals would arrive at any antennas first.

If you look at those antennas installation inside the laptop, not all have the same positions. One laptop could have all the three antennas installed inside the LCD frame (and could be plus 2 more if it has 3G antennas). But others might be installed only two, with the 3rd one installed on the edge inside the laptop's palm rest. And many other configurations should be considered, such as spacing between antennas. At least for the left and right antennas on top of laptop's LCD frame would have different spacing according to laptop's screen size. Not to mention spacing to the 3rd antenna if it is not located on the same area of the first two.

Now on the wireless router side, not all wireless n routers transmit/receive using 3 antennas. Low budget ones use only 2 antennas but still with channel bonding (or wide channel 40MHz) they could have connection up to 300Mbps. So, two spatial streams of radio signals would travel in the air and would be mainly received by two antennas on your laptops. The 3rd one will help in case it can pick the signals while the other two couldn't.

More on the wireless router side, the location of these 3 antennas in the wireless routers would also be different according to manufacturers' design. One could have the 3 antennas installed in one side, other models could have 2 antennas installed on left and right side of the wireless router with the 3rd one on different (i.e. front) side of the wireless router, and many other possible configurations.

My point is, don't be too worried about the antennas arrangement. What matters is that they are all connected.
