About Intel 4965AGN Wireless-N Mini Card .

How abou ur 4965AGN wireless card?
Did u use N speed? or just G speed?
Also your wireless card connect 3 antenna or 2 antenna?

 

I haven't opened it, but it ran nicely at N speeds with a Dlink N router, but does simliarly well at G speeds with my primary G router.

 

i bought 10 xps m1330 same feature with 4965AGN card for my business.
when i check 10 xps m1330 all of them just connect 2 antenna.
so i request about dell. they said 2 antenna is right. but dell tech said 3 antenna is right connection. anyway we use d-link 655 n router.
but all laptop wifi maxime speed is just 54.0mbps.

 

The third antenna port is for the 801.11n... If they are not connected you can only use the b and g...

 

they only connect 2 antenna from factory...

 

That is why you are only getting 54mbps, can't go higer without the N antenna. That's a bummer.

 

How do you check this on a 1530 ?
I mean where is the card and how do you get to it ?

 

i use it on g and its very good upto now. i connect to my home netwrok via linksys wrt54gs, and in uni via access points.

Both networks are wpa2 secure

 

I have this card and use it with d-link 655 as well without issue. 2 antennas does seem to bo the norm, 3 antennas is NOT required by the 802.11n draft spec. The other antennas are for the wireless broadband option.

Max speed you will be able to get with the 4965 + d-link 655 is 130mbps due to the fact that the 655 is 2.4 GHz only. Intel does not allow channel pairing with their hardware in the 2.4 GHz band b/c they feel it is too crowded. This is Intel's own arbitrary decision and is one of the main sticking points why 802.11n hasn't been officially certified yet. Channel pairing is required to acheive the max 300mbps bandwidth and the 4965 currently only supports this in the 5.0 GHz range. This means that unless you get a 5.0GHz or dual-band router it is currently IMPOSSIBLE to get full theoretical bandwidth with an Intel 4965 wifi card.

That being said, I have a 4 floor townhouse and I get my max 130mbps on all floors with 80%+ signal quality. This beats my old Dlink MIMO 802.11g router which would usually degrade to 50% signal and 24-36mbps when going between multiple floors. So I have personally seen the gains. I also use Windows Media Extender to stream 720p WMVHD to my Xbox360. This was impossible using my old 802.11G laptop, but is perfectly smooth with my 4965 @ 130mpbs...which after all slightly faster than my 100mbps wired connection. So there are definitely tangible real world advantages to draft-N, even without the full "theoretical" speed.

 

I always seem to get 144Mbps, that is with the later driver from the intel site.

 

I haven't tried the latest intel driver yet (using the stock dell driver), but that would make more sense b/c channel bonding doubles throughput and 144 x 2 is closer to the max 300mbps. I'll have to download it and give it a try.

 

i used d-link 655 router. i need to change router? or fix wireless card?
what am i do?

 

Well there are several factors at play here.

First, I would upgrade the router to the latest firmware and 4965 to the latest driver (good advice for any wifi device).

2nd, how far away from the router/through how many walls/what is the construction of your building/house? In a steel/concrete/block construction building your going to lose a lot of signal. Same goes for more wall/ceiling penetrations. My router is 2 floors down from my bedrooms...often times my speed will be only 52mbps when i sit on my bed b/c it then has to penetrate the thick mattress as well as walls/ceilings.

3rd...are you using the correct security settings? Wifi security must be set to WPA/WPA2 (WPA2 preferrable) to get N speeds. (search forums for the dlink 655 router, this has been covered numerous times)

4th...you're getting 54mbps. If using 802.11g it would likely be lower. Is it really affecting your networking useage? ie: slow web browsing, random network dropping out, slow file access?

 

I hope this thread isn't too old to supply some help. I just got a Intel 4965AGN and am going to replace the Dell Recommended P.O.S. that I screwed up and ordered with my wife's new Inspiron 1525. I took a peek inside already and there is a black and a white antenna hooked to the existing card. Unconnected there is a choice of a blue, thick gray or smaller grey antenna. So the question is, Which one should I use? Do I hook it into the middle and keep the black and white on their current sides of the card. Sorry about the blurry picture, I was hurried. Thanks in advance for your help.
