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,
