Hello Folks
My sony notebook FZ31S has the Intel 4965 AGN wireless N network card installed. My notebook can connect to my ADSL router (D-Link DSL 2740B) at only 130 mbps, not at 270mbps. My desktop upstairs has an Edimax Wireless N PCI card, and that connects to the dlink at 270mbps, no probs. On the router i am using "wireless N only" broadcast and am using WPA2-AES encryption. I also have the latest driver installed for the 4965AGN card (12.2). So why can't the Intel 4965AGN connect at speeds greater than 130mbps?
Edit: I should also mention that on the sony's wireless utility, i have the option of using 5ghz or 2.4 ghz. If i select 5ghz option only then my notebook can't connect....it only connects if the 2.4 ghz is selected (with or without 5 ghz)
Thanks![]()

goto Wireless Network Connection icon in network connections, click the bottom Properties button, then under where it says Intel(R) Wireless WiFi Link 4965AGN, click the configure button and have a look at what the settings are in there, sometimes these network utilites from the hardware makers have different settings by default.

According to D-Link, you can only achieve 130+ Mbps if your Intel card supports 40MHz channel width. (I have slightly different router, DIR-655 but concept should be the same)

Thanks for your replies. Well according to Intel the 4965AGN does support 40 Mhz channel width, but only in the 5Ghz spectrum. On my notebook, i cannot select the 5 ghz option on its own...it can only be selected with the 2.4 Ghz option. However could the problem be that the network card in my notebook only has 2 antennas whereas some versions of the card have 3 antennas which allows speeds of up to 300 Mbps?
Thanks -
Doubt it's the amount of antennae. It's probably the fact that you're using mixed mode instead of just 5GHz.
-
I had this problem as well. I changed my router setting to 5Ghz and I also changed the channel width from the default 20Mhz to Auto 20/40Mhz. Now I get the full 300 mbps.
-
The i4965 will only do 300Mbps in 5Ghz.
They not made it 11n for 2.4Ghz siting congestion with 40Mhz channel width (a load of hog wash I saY)
-
yes it appears that my router has to support 5ghz to get 300mbps speeds on the Intel (the Dlink 2740B has only 2.4 ghz). But can i ask why my Edimax PCI card is able to give 270mbps speeds in the 2.4Ghz frequency (using 40 Mhz bands) yet they restricted the intel card to 5ghz for 300mbps?
Would i need to buy something like this when its released?

Make sure the router you get can do both 2.4Ghz and 5Ghz at once.
Some routers can only either not both at once (you'll regret this)
The Netgear one doesn't say simultaneous so best do some more homework. -
I'm not interested in full 300mbps, but I want the simultaneous dual mode for all the pcs and game consoles in my house. The Linksys is cheaper and I could get it at BestBuy, but I have heard and read as much negative as positive about it. -
According to Netgear these are the specs of the DGND3300:
Wireless Configuration
* Type 1: Full 2.4 GHZ configuration supporting 802.11n/802.11g/ 802.11b
* Type 2: Duo 2.4 GHz and 5 GHz configuration supporting 802.11n/802.11a (5 GHz) and 802.11g/ 802.11b (2.4 GHz)
Surely Type 2 means that its simultaneous 2.4 and 5 ghz?
Thanks -
I believe the 5300 will actually get 270Mbps. -

I have a 5300 (full size) installed in a Eee PC 900A mini laptop.
That isn't exactly the best performance bench for finding the limits of the 5300 but the purpose was enhancing the 900A which it did.
In addition to the existing two antennas that was used with its original "Azurewave" card I added a third small centre antenna I picked up off Ebay. I have no idea how critical antenna routing is inside the laptop.
Anyway it works in an excellent way with the Intel PROSet connectivity tools
and I can move back and forth easily between being connected to the
5 GHz or 2.4 GHz router bands of my DIR-855.
I have it connected to 100 Mbit/s WAN that offer appr 98 Mbit/s effective capacity on the switch ports. I can accomplish at least over 50 Mbit/s wireless throughput effective with the 5300. I do see it establish a 270 Mbit/s link so that works. Indeed this card is one cool deal om Ebay where they are sold on the cheap by HongKong sellers. -
There was a thread in the Gateway forum indicating that Intel does indeed limit your bandwidth unless you are using 40Mhz (N only) in the 5Ghz range and using the higher modes of security.
My 4965AGN connects at 270Mb/sec on the Linksys WRT610N (5Ghz band/N only/40Mhz) while still allowing older computers on my network to operate in the 2.4Ghz range.
Possible to get >130mbps on Intel 4965 AGN?
