Problems with dsl connection dropping often? Turn off autotuninglevel in windows 7

I had some problems with my dsl connection after service pack 1 for Windows 7.
After some hours on google and searching i found this trick:

I turned of  autotuninglevel in windows 7. Simple and easy !

How?

Open command promt (type CMD in start and search) or find command prompt in :
Start/all programs/accessories , Run as Administrator
Copy this and paste, then Enter:
netsh interface tcp set global autotuninglevel=disabled

Works in Vista and Win7, But may not fix your problem.
My trouble was just after installing Service pack 1 in Windows 7
