I posted this in the M1330 thread also since we were talking about it in that thread awhile back, but this relates to anyone with the DIR-655 or anyone using the atheros chipset and using the intel 4965
Ok I figured I'd post the finding I have found on this topic. I have the m1330 with the intel 4965. Right now the 4965 will only connect to the router at 130mbps or 144mbps for some. It only uses 20mhz (130mbps) at the 2.4ghz range and then uses the 40mhz (270 or 300mbps) at 5.4ghz. I'm using the router DIR-655 and it has the Atheros AR5008E-3NX chipset in it http://www.eetimes.com/showArticle.jhtml?articleID=201800278&printable=true
In order for the intel 4965 to actually connect at 300mbps speeds you will need a 5ghz router. So far the only one out now is the Airport one. D-link is coming out with one later the DIR-855. But there have been problems with the 5ghz and 40mhz if you do asearch. Now if you want to connect to the DIR-655 you can purchase this
http://www.oxfordtec.com/us/MiniPCI...-Atheros-AR5008E-3NX-AR5418/product_info.html THis card is teh same chipset as the one in the DIR-655. This router is nice if you read the EEtimes about the new chipset the 3-3 MIMO
They also sell antennas. I'm going to try this card out and install an extra antenna try going around the keyboard area. which will create a Y shape in the notebook. With this you should be able to achieve 300mbps since it is teh same chipset. I had a pcmcia card that fit this router and had 300mbps so I know it can be achieved at the 2.4 ghz. I'll post and let you know the results. Now one will never be able to truely achive 300mbps but i got faster transfer rates with the pcmcia and at 300mbps than i am with teh 4965.

Ok your links dont work for me.
I will just say this: Make sure you get a minipci express card and not the normal minipci card. Also check in the dell forum if the M1330 uses a normal full size minipci express card. You don't need any extra antenna. You should already have 3 of them.
As an alternative to buying a new card you could gets get a Draft N router with a centrino certificate. -
Thanks. Links fixed
-
Also, I would like to ask if there is a site where I can check whether my router is "centrino" certified or not. I am using DLink DIR-625 (n-draft 2.0 wifi alliance certified). -
Murdoc hit it right on. Dont know why, but i'm out for distance on wireless so 3rd wire would hurt also. the chipset in the DIR655 is 3-3 MIMO, and i think you have to have the 3rd wire to achieve this if only two wires then you only get the 2-2 MIMO.
What intriges me is that if you look at the spec sheet of the AR5008-3nx it has support for the 5ghz range. Wonder if the DIR 655 could be upgraded to the 855???? HMMMMM -
I have the 4965 and mistakenly bought the Linksys 350N.
Right now I think its impossible for the 4965 to connect at 300m to ANY router. I was just about to post to see if anyone had ever connected at this speed (with this card) and then spotted your post... -
you can connect to 300mbps if you have a 5ghz router. Right now the only one out is the Airport one. The 5 ghz range will use the 40mhz which achieves the 300mbps

The dir-655 can toggle between 20/40MHz,use auto which will turn off channel bonding if a near by network is detected, and just plain 20GHz which will not give you the speeds/or constant speed you desire.The only router I know that's out now that can be just set to use the 40GHz bandwidth it the linksys wrt300n.

wait, the DIR-655 doesn't support 300mb out of the box? my router recently died so i bought this 655 as i needed a router, and i'm about to order a new notebook with a draft-n card.
should i just wait for the 855, 5Ghz since i don't even have a draft-n device yet?
also, i'm going to setup a Gigabit LAN with the three wired devices. and I don't mind getting a separate Gb switch and wireless-g router if there's no way to achieve high bandwidth potential of draft-n anyway. what's the best option in this case? -
You could wait,it's really up to you.But personally I'm going to wait until wireless N is ratified before I purchase anything wireless N.Wireless G work just fine IMO.
-
Yes the DIR-655 can connect at 300mbps. I bought the associated card that goes with the router and I connect at 300mbps. I still have not recieved the product yet to try out. I ordered later than i wanted too. I'll have an update as soon as i get it and install it.
-
Actually, my LED-backlit m1330 has 5 cables:
3 connected to intel 4965 card (black, white, grey/black)
one connected to dell 5505 WWAN card (grey/white)
one unused (blue) -
To get 300mbs you need to hire the 300mbs service with your company right? which companies offer this speed? which one is the fastest available now?
-
300mbps is not common in the US from an isp . Maybe in Hong kong. Most people's broadband can be handle fine by a wireless G router. We are (at least me) are worried about local network traffic. Streaming and such off a local computer

@ Fezzik: What firmware were you using on the Dir655 with the intel 4965agn? I thought this compatibility issue was solved with 1.03 http://www.dlink.com/products/support.asp?pid=530&sec=1#firmware
Im planning to buy the 655 and have the 4965...so this is an issue for me. If I should wait for the 855. Any ideas when it should come out? Thanks -
This is with any firmware of the DIR-655. I am currently running 1.05. The DIR-855 should work at the 300mbps, but it does not come out until later this year or even next year. If you dig through the net, a lot of reviews of the 5ghz routers have not been very good. There are lots of bugs with using the 5ghz. Maybe D-link will have that ironed out when they release the DIR-855
-
Yeah, I figured it out yesterday, that the problem is with 4965 not wanting to use the 40Mhz. Thanks, bye
-
this 300mbps problems seems to be bond to the intel 4965 agn card only.
i have both intel 4965 and a dell 1500 n-draft card and while the intel card can only connect at max. 144mbps the dell card connects at 270mbps and is much faster then the intel card. my router doesn't support 5ghz, it is a netgear rangemax WNR854T. so what's up with this magic 300mbps? -
There may be a setting somewhere for the 4965 where you have to tell it to allow 300Mlb. transfer. Not sure but I know some have that
-
you don't have any clue where to find these settings? i tried nearly all possible configuration settings but it didn't help. i also had to adjust some setting with the dell card to get the maximum speed, but haven't found anything similar for the intel card.
i would really prefer to use the intel card if i managed to get it connect faster, because the dell card interferes somehow with my graphics card, from time to time i get some stuttering 3d-performace which disappears when i turn off wlan. this doesn't happen with the intel card though. -
For the intel card you have to have a 5ghz router. That's it. Intel will only use the 40mhz (to achieve 300mbps) in the 5ghz band.
So for intel card to get 270-300 you will need a 5ghz wireless router. -
Looking at this link
http://www.oxfordtec.com/us/shopping_cart.php
Does this mean its a standard mini pci express type of card which would plug n play ?
I have have the intel 4695agn card in my laptop, if I purchase this new card would it just plug n play ( replace the intel card )
Thanks -
yes...plug and play
-
I have the netgear wnr854t and the intel 4965agn and of cause the highest transfer-rate is 144mbps. What do you think is it a hardware limitation of the intel wireless lan card that it can only connect at 5ghz with 300mbps or is it the driver???
-
its hardware.
-
Anyone got experience with the WPEA-124N.
I am kinda almost buying the card. Cause my DIR-655 and Intel 4965 agn card.
I got constant connections drops (which recover very fast). It this a 4965 problem and will it be solved by replacing it by a WPEA-124N ? Or does it come with its own problems...
Thanks for the help -
Atheros ar5008 chipset solves the problem, so your good.
-
And which one of these Atheros ar5008 variations do we need? Just the " AR5008E-3NX"??
Also, where can I get a card with AR5008 in the USA (preferably a mini PCI, not an express card)? From this list I see that Gigabyte and SparkLAN make some. Any other manufactures?
I don't know anything about that OxfordTEC site... any more popular etailers selling them?
It now seems pretty lame that most of the notebook manufactures are supplying the 4965 -
Yes, the AR5008 can use 40MHz channels @ 2.4GHz. I used my with a D-Link DIR-655 @ 2.4GHz for a while, before I replaced the DIR-655 with a DGL-4500. My card is the Gigabyte GN-WI06N-RH, which was about $40 at ClubIT.com a few months ago.
Do note, however, that you'll need realtively low interference levels for the router and card to operate in dual-channel 40MHz mode. You'll most likely have neighbors with 802.11b/g routers, so your DIR-655 will bounce back & forth between 20MHz and 40MHz mode frequently when the neighors are using their routers.
