Slow Internet using Windows Vista (Vista Auto-Tuning) fix

Yesterday I did find the fix to increase my Internet speed.

Since I did get my new computer for some weeks ago, my Internet speed have been quite low, so yesterday I wanted to research more about the problem, and found many other people, who did have the exact same problem, when using Windows Vista, Normally I download with 1000Kb/s but after installing Windows Vista 64 bit, my top speed was about 300Kb/s.

That isn't good enough, when I pay for about 4 times better Internet speed. After some research I read about people having problem with Mcafee, and their Internet Phishing settings, which couldn't be my problem, because I didn't have Mcafee installed.

If you're having the same problem with the Vista slow Internet speed, and installed Mcafee, you maybe got this problem too.

My problem was Windows Auto-tuning, which I didn't know about, before researching about this problem. So the fix to increase the Internet speed for me, was to disable this Windows service, restart the system, and then I did get full speed on my Vista machine again! Here is the instructions to disable this Windows Auto-Tuning service.

Disable Receive Window Auto-Tuning Level on TCP/IP

1. Open a command prompt with administrator rights.

2. Input the following command, and press Enter when done:

netsh int tcp set global autotuninglevel=disable

3. Restart the system.

If the problem still exists, you always can return it back to default by following these instructions.

Enable Receive Window Auto-Tuning Level on TCP/IP

1. Open a command prompt with administrator rights.

2. Input the following command, and press Enter when done:

netsh int tcp set global autotuninglevel=normal

3. Restart the system.

 

Hope you could use this blog about the Windows Vista Internet speed problem.
