I've read through the whole thread now but none of the solutions seem to work. I have the exakt same problems as the first (and some of the other) posters.
I can easily force it to occur by going to www.diablo3.com and playing the two trailers over and over again (empty cache in between). This always make the problem occur.

I've googled my *** off about this, and this thread has so far been the one with the most users experiencing the same thing

So far I've tried:

(using Zepto Znote 6214W laptop with Intel Pro/Wireless 3945 running vista x64 SP1)

-Tried several different router firmware (including dd-wrt)

-Turned off UPnP on the router (have heard it helps)

-Tried a registry tweak adding "DhcpConnDisableBcastFlagToggle" with value "1" to the NIC registry. (supposed to help, but didn't)

-Turned off all energy saving options for the NIC (network interface controller)

-Tried several different drivers for the NIC (currently using the latest)

-Tried several different options in the configuration for the NIC

-Ran the command: netsh int tcp set global autotuninglevel=disable (supposed to help, but didn't)

-Unchecked IPv6

-Unchecked QoS and the two layer stuff things.

Please HELP!

I've tried everything, but haven't found a solution yet and this is getting very frustrating!

[size=4]YES![/size]

I finally found out how to disable the Toredo Tunneling Pseudo interface and it has stopped dropping the connection!

It's been explained earlier, but I'll do it again for new users:

Go to the device manager
Show all devices (or show hidden devices)
Go down to network devices
Find Toredo Tunneling Pseudo interface and deactivate it!

Cheers! I never figured where that pseudo thingy actually was.

Well, I've tried the router fixes and now disabled this - let's see if it helps.

I just got disconnected again as well. The odd thing is that it has worked flawlessly since I disabled the Teredo tunneling thing, right until now.

Back to square one...

The only thing I have done since I thought I had fixed it was to reset the MTU size on the router to 1500 because our 3D-printer had some network problems after I had reduced it to 1450 (or something like that). Maybe it's the combination of making the MTU size smaller and disabling the teredo interface..? I don't know anymore, and I just feel like getting a brand new laptop right now..

People, here is your solution, works 100%!!
The issue with the WiFi adapter is caused by incompatible Vista driver, as the problem does not happen under Windows XP system. Previously, users have used two workarounds as a temporary solution - “XP Fix” which uses Intel PRO Wireless 3945ABG driver designed for Windows XP, or rollback and switch back to Microsoft driver comes with Vista for Intel PRO Wireless 3945ABG network card. However, these workarounds have an drawback and disadvantage that the Wireless network or LAN is not optimized for fastest possible speed, instead opt for lower reliable speed throughput, and also have poor radio signal level problem.

Luckily, Dell has released a new updated driver supporting Intel PRO/Wireless 3945ABG Network Connection and Intel Wireless WiFi Link 4965AGN. The driver version 11.1.1.22 dated 08/08/2007 comes from provider Intel, is packaged as R164259 (11.1.1.3) - A05 - August 2007 release. It fixes the following bugs (changelog):

* Addresses 3945ABG radio disable seen with some systems running with Bluetooth modules
* Addresses 3945ABG radio disable seen in some 802.11a environments after Standby or Hibernate
* Addresses installer upgrade behavior where Windows Vista Preferred Networks would be lost
* Addresses installer interaction with InstallShield Update Manager causing an unwanted prompt during installation

The new driver will likely to solve the Wireless cuts off problem in Vista. Download the driver version 11.1.1.22 from ftp://ftp.dell.com/network/R164259.EXE. It’s a Dell installer package, which should works on other brands too. Otherwise, simply extract the driver by using WinRAR and manually update the driver for the network card from Device Manager.

Post your outcome. This should fix it!!
