Wireless 4965AGN does not provide speeds higher then 72 Mbps

[idata]

I just upgraded my Toshiba Satellite M155 S3154 laptop from its original intel model WM3945ABG wireless card to the intel 4965AGN. I added a new Trendnet 300 Mbps Wireless Easy-N-Upgrader TEW-637AP wireless access point. I installed the latest 4965AGN driver and the latest firmware for the WAP. I followed the directions for the WAP to allow for G/N communications - I still have one laptop that uses G. I tested all 11 channels to see which channel provides the best communications. There was really no difference in the 11 channels so I set the channel to "auto". After doing all these tasks, i get no higher then 74 Mbps. Communications speeds varies between 58-72 Mbps. I am using WIndows 7 32 bit Home Edition. I get these values by opening the network and sharing center and then opening the wireless network connection properties. Signal strengths remains on 5 bars.

I noticed that when i replaced my original wireless card, it had two connectors for the attenna; however, it seems that the 4965AGN has connections for three antenna wires. they are labeled 1,2 and 3. The original card's antenna connections were not labeled. so I connected the black wire to the same end connector on the 4965AGN card as the original card and the white wire to the same end connector as the original card. Nothing is connected to the center connector on the 4965AGN.

Can anyone tell me (1) do have that the antenna connections correct and (2) how can i increase speeds to over 72 Mbps as N is suppose to provide.

Hello,

The Intel® Wireless WiFi Link 4965AGN is designed with a 2x2 (2 Transmit/2 Receive) antenna configuration, thereby supporting up to a 300 Mbps data rate. The third, middle connector is auxilliary. Please see the product brief and the comment below about antennas. Although the latter discusses installing and upgrading, the concept applies to manipulating antennas. Another community member seemed to find 802.11n configuration settings that enabled his AP/router to connect at higher data rates.

/message/81923# 81923 Can the Intel 5300AGN Be replaced with an 6300 or the wireless-n1000 ?

Installing or upgrading the various Intel wireless adapters by end users is not supported by Intel. There are many reasons for this. I recommend that you review the information at http://www.intel.com/support/wireless/wlan/sb/CS-031167.htm http://www.intel.com/support/wireless/wlan/sb/CS-031167.htm and<span lang="EN" style="font-size: 10pt; color: # 3...

tpgrec,

Thanks for the information. Unfortunately, the changes I made to my router to the settings listed in your post did not work. I also changed routers and still have the same problem. I now an connected to d-link DIR-625. My settings correspond with your post but I only get 65 Mbps. I have a clear path to the router and the router is only about 10 feet away.

Since I am experiencing basically the same problem with two different routers, could there be some issue with the card - I have updated it to the latest driver - or my computer?

I've had a similar issue with the 4965AGN that's onboard in my Acer Aspire 5920 laptop. It won't provide anything more than 65 mpbs no matter what I do/try. Other computers on my local network connect no problem at speeds > 150mpbs but the 4965 refuses to seemingly. I have the latest drivers, have tried all the settings mentioned in http://www.intel.com/support/wireless/sb/CS-030709.htm http://www.intel.com/support/wireless/sb/CS-030709.htm and it just won't step up. (Interestingly, the "Throughput Enhancement" setting is not an option that's available for setup........).
