Intel 4965AGN only connects at 130mbps when using 2 antennas?

Hi all, I bought a Intel 4965 to go with my dell 1520 because they stuffed up my order and put in the 3965 instead. I put it in my old Sony FE which only has two antennas and it only seems to connect at 130mbps.

 

Try to repair the network, then It might connect at 300 mbs.

 

I have the same problem. I have tried adjusting settings for the wireless, but to no avail. I think it could be a couple of things for the Intel 4965AGN:

1. Drivers are not optimized.
2. Mismatch between 4965AGN chipset and router's chipset.
3. Firmware has not been optimized for the 4965.

Honestly though, this is a pretty common problem with wireless N. It's only in draft 2.0, and there may be some changes that could fix the problem in the production release.

 

You won't get 300mbps unless you have three antennas.

 

The Intel 4965AGN has 3 antennas, and it only connects at 130Mbps.

 

Mine too connects at 130, my router has 3 antennas..

 

Not the router, the laptop. If the laptop only has two antennas, then the laptop will never connect at 300mbps. The OP had a problem installing a wifi card that has three antenna connections into a laptop that only has two antennas.

As for only connecting at 130 when the notebook has 3 antennas: the Intel cards are notorious for not connecting at 300mbps on D-Link and other routers.

 

Do you know if it is possible to swap out wireless cards on a Sager NP2092?

 

I don't know if you can swap cards on any Sager laptops. You should ask that question on the Sager board.

 

Ok guys this is the thread i need i have dgl-4500 gaming router and dv9500t with intel 4965AGN/bluetooth chipset mine too says only 130mbps what i think we should do is start providing tips tweaks drivers etc....to get to 300mbps I am guessing that this is possible but just need imput to get there....any help would be great!!
thanks

 

As kegobeer said, if the card only has two antennas connected, it will only connect at 130mbps. Your wireless card probably only has 2 antennas. Check it out.

 

nope already checked has 3 antennas as does the router

 

Interesting. I have the same wireless card as you do, so I wonder if it is just a driver/firmware issue...

 

what router (i have D-Link DGL-4500) if its the same will u give me the link to the firmware page? ill c if it matches mine

 

I have a Trendnet TEW-633GR Wireless N Draft 2.0 router.

 

If Trendnet has a forum, check it out - there may be compatible wifi cards listed. You can do the same for your wifi card. I'll just go ahead and guess that it's a mismatch of hardware.

 

I believe D-Link has a notebook card that allows you to achieve the max 300Mbps (or up to), in conjunction with your wireless-N router.

Yeah, I'm getting 130 Mbps with my 4965AGN and D-Link DIR-655.

 

Okay, I think I have found out the cause of 130Mbps connections on the Intel 4965 wireless.

The Intel 4965 does not support channel bonding on the 20Mhz / 2.4Ghz spectrum. Meaning, if your router broadcasts 802.11n on the 2.4Ghz range, and it doesn't support 40Mhz channel bandwidth, then the Intel 4965 will only connect at 130Mbps. If the router is broadcasting 802.11n in the 5Ghz / 40Mhz frequency, then the Intel 4965ABGN will connect at a full 300Mbps.

They are basically trying to push the 5Ghz spectrum because 2.4Ghz is so crowded with devices. I think their mentality is that a 802.11n signal @ 2.4Ghz would have a tough time transmitting the theoretical maximum of 300Mbps.

Here's the source:

You can blame Intel on this one.

I wonder if it would be possible to hack the firmware / drivers of the wireless card to enable channel bonding @ 2.4Ghz / 40Mhz.

 

ok so from what your saying you cant run both freq at 1 time to get the speeds u have to commit to 5ghz which sucks for me considering i have 2 other g laptops i should have bought the wrt-600n it does both anyone want to buy my dgl-4500? LOL

 

This could *theoretically* change if Intel releases a new firmware /driver that enabled channel bonding on the 2.4Ghz spectrum.

I wouldn't be too upset over it though. 130Mbps is still pretty fast. There aren't too many routers right now that broadcast 802.11n in the 5Ghz range, and the one's you will find are going to be very expensive.

All in all, if you want to get 300Mbps on the 2.4Ghz spectrum, you need to get a different wireless card.

 

yea i have HP dv9500 i dont think i can switch it?? who knows?

 

If it's mini pci-express, then maybe. It would be a major pain though. I have done a bit of thinking on the incompatibilities of this wireless card. I think Intel may be on to something with this, because 2.4Ghz has some downfalls. 2.4Ghz has issues with interference, and with a high speed format such as 802.11n, this will cause a lot of issues (slowdowns, disconnects, etc). From what I have read, 5Ghz provides more bandwidth, and is more reliable for 802.11n. The only issue is the signal does not go through walls as well as 2.4Ghz does; however, this is somewhat offset because of the throughput of the 802.11n. I am going to keep my router, because it is a very nice one regardless. I will purchase a 5Ghz 802.11n router when the price comes down a little, and the performance increases.

 

Hi.
I have the Intel 4965AGN, but i only have a NETGEAR DG834GT 108 Mbps

Does the Intel 4965AGN support 108 Mbps, as it only show 54 Mbps on the taskbar.

Is their a util to give me more information on my connected speed.

thanks

John.

 

No. You will only get 54Mbps. In order to get 108, you have to use all Netgear products.
