Wireless Issues w/Inspiron E1505 w/Vista, integrated Intel 4965AGN w/Netgear WNR834M Router

I am unable to achieve connectivity at 130 mps.  When I set the router's Mode to 11b/g/Next the laptop  connects to the router with only local access (no Internet access).  When I set it to 11b/g, it connects just fine, but at the 54 mps speed.
 
Wireless Optimization Settings are at 11n max speed.
 
Any help getting this resolved will be greatly appreciated.  The new is quickly wearing off on this new laptop after many hours on the phone with Netgear.
 
Thanks.

With the limited info you've posted, it sounds like there's a bug (conflict) in the router's firmware, the Intel 4965 driver... or both.

Netgear has a WNR834M "Vista BETA firmware", available for download on "this page", that you might want to try...

In the release notes for the latest "Intel 4965 Vista driver" ("click here" - Version: 11.1.0.86 / Release Date: 3/23/2007), Intel lists this under "Known Issues"...
Operating in 802.11n Mode

Intel recommends using security with your wireless network. The Intel(R) Wireless WiFi Link 4965AGN adapter can only achieve transfer rates greater than 54 Mbps on 802.11n connections when using AES security, or no security. You should only use no security when setting up or troubleshooting the network.

To enable AES for Personal Security, select WPA-Personal (AES-CCMP) or WPA2-Personal (AES-CCMP) in the Security Settings pulldown menu. To enable AES for Enterprise Security, select AES-CCMP in the Data Encryption pulldown menu.

The Dell Intel 4965 Vista driver ("click here" - Version: 11.0.0.74 / Release Date: 2/20/2007) is an "Initial Release", so it's probably the one you're using...

Aloha,

Akule50 you are too kind.  I have already installed the Vista firmware, and have the most recent 4965 driver as you suggested.
 
I changed the Wireless Network Mode from 11b/g to 11b/g/Next and the Security Options from WEP WPA2-PSK (AES) as you suggested. This did bring the speed back up to 130mps on the wireless connection.
 
However, at that setting I have sudden losses of connectivity from my desktop computer which is plugged into the 4965 router.  Sometimes a reboot of the desktop computer restores connectivity, sometimes I have to cycle the router.  My desktop is running XP SP2.
 
Do you have any idea how I can get both the hard wired desktop and the wireless to remain connected with the above listed settings?  Is there something I need to do in my network settings on the desktop?  When I into those settings I do not see the 4965 so I assume the cable connection is just passing through it.  I hope that I am missing something simple.
 
Thanks!

I would shoot off an email to Netgear ("click here") explaining the problem... just to have them aware of the problem with WPA2/AES between the router and the latest Intel 4965 Vista driver.

WPA2 usually uses more of the router's resources to implement and might overheat (slowdown / hang) or lockup some routers...

Have you tried the WPA/AES setting?

I don't have access to a Vista system or your setup, but there are others that had similar problems with Vista and various setups ("click here")...

You might also want to check if you have something like this ("click here") in your wireless properties (Device Manager).

Vista Network Discovery feature (which allows other computers to see you on a network) will switch off automatically if you designated your connection as "Public"... you might need to enable it manually in the "View Network Status and Tasks" control panel.

With password protected sharing enabled in Vista, other computers on your network will not be able to access your shared folders... ("click here")
When you disable password protected sharing, the computer sharing the folder does not require a user account or password (equivalent to simple file sharing in WinXP).

To disable password protected sharing, do the following:

1. In the Sharing and Discovery section of the Network and Sharing Center window, click the down arrow next to Password protected sharing.

2. Within the Password protected sharing settings, click Turn off password protected sharing, and then click Apply.

Thank you so much!  The information found Here (last post on the page paragraph 3) seemed to have done the trick.  It was disabling the UPnP that appears to have solved the intermittent connectivity issue for the desktop which makes sense.  The funny thing is that the documentationn for the 4965 says that the default setting for UPnP is disabled, but it was enabled, perhaps by installing the required Vista firmware. 
 
At any rate, it has been several hours since I changed this setting and I am still at 130 mps on the latptop with the WPA-2 setting, and I have not lost connecitivity on the desktop since the change.
I am crossing my fingers that this sticks, and thank you kindly for your help.
 
Your screen name is certainly appropriate!
 
Peace

I guess you probably might think that it's pronounced "A-kool fifty"? (LOL)

I've listed the pronunciation below my Sig... Akule50 is pronounced "Ah-coo-lay fifty" or "Ah-kuh-leh fifty".

An "Akule", here in Hawaii, is a type of fish ("click here") that travels in a school of Akule ("click here"). There can be thousands of Akule in the school ("click here")...

I'm an "Akule fisherman" (ultra-light (4 lb. test/line) finesse whipping / jigging style) and Hawaii is the "50th State"... hence, the screen-name.

The "Akule" is one of the most popular fish to catch here, in Hawaii, because it's pretty tasty. But my wife's uncle said the Akule where he now lives (California) doesn't taste good...

Aloha,
Rod

Actually I was referring to a fish that runs in schools since you are such a true community member being so willing and able to help others!  But, I suppose even the incorrect pronunciation would have fit due to my gratititude.
 
My screen name refers to a small town in Belize on the Guatemalan border where my wife is from.
 
Thanks again Rod!
