Vista - Unsolvable problem

Since my next computer will probably have to come with Vista, when the
Penryn dust settles, I need to understand this issue but I can not find a
solution. I have posted this issue on these newsgroups but I can never find
the posts
I can live with Vista's many other flaws but this is the deal-breaker:
My computer dual boots XP and Vista 32 bit.
The machine is a dual core, fast Nvidia video card, 2 gbs of ram. Vista
drivers are all up to date.
The computer is wired into the dsl router, not wireless.
Vista and XP are on identical but separate hard drives.
In XP the computer has stable internet connections and streams audio and
video flawlessly from mulitple sources using multiple players.
In Vista there are frequent halts for rebuffering, regardless of internet
source or player, to the point where it is impossible to listen/view
streaming internet media. However Vista can download large data files
without interruption.
I have tried turning off the anti-virus program (Avast) and the firewall
but the problem persists.
Judged by the Task Manager/Performance monitors both CPU and memory usage
are at very low levels when the hiccoughing occurs so background processes
are not overwhelming the system.

Hello flambe,

Have you tried disabling TCP Receive Window auto-tuning? This may be what is
causing your network connection to drop -- most of the time, this feature
works without an issue but some routers and internet connections have issues
holding a stable connection with it enabled.

To disable TCP Receive Window auto-tuning:

1. Click on the Start button, click on All Programs, click on Accessories,
right-click on "Command Prompt" and click on "Run as administrator".
2. If User Account Control prompts you for consent, provide the appropriate
credentials or provide consent.
3. In the command prompt window, type the following command:

netsh interface tcp set global autotuninglevel=disabled

4. Press enter on your keyboard to run the command.
5. Save any work, close any running applications, and restart your computer.


If this does not resolve the issue, you can safely turn the feature back on
by performing the following actions:

1. Click on the Start button, click on All Programs, click on Accessories,
right-click on "Command Prompt" and click on "Run as administrator".
2. If User Account Control prompts you for consent, provide the appropriate
credentials or provide consent.
3. In the command prompt window, type the following command:

netsh interface tcp set global autotuninglevel=normal

4. Press enter on your keyboard to run the command.
5. Save any work, close any running applications, and restart your computer.

Please let us know if this makes a difference for you and have yourself a
great day,
